FmNT Features FmNT is designed for a wide range of users to simplify programming and testing of complex dispensing routines that require explicit machine and fluid controls. Menu access is restricted by passwords, while providing the user the flexibility needed to complete the job efficiently. Some of the features that make FmNT a flexible and easy-to-use benchmark for dispensing system software are briefly described below.
“Height Sense Always” Mode When the “Height Sense Always” mode is selected, the dispense height is set as the distance between the needle and the board at the moment the height sense probe detects the board. The board height is sensed on each dispense instruction. This mode is useful on large boards where the dispense height may vary across the board or when the dispense gap is critical, such as when dispensing very small dots.
Advanced Heater Options FmNT now supports the following heater options. See “Heater Controls” in the Tools section. Dual Heater Control FmNT can control two Anafaze heater controllers. Idle Timer for Heaters Each heater channel can be configured to automatically turn off after a pre-programmed amount of idle time. Idle time is defined as: (1) no boards have arrived for the specified amount of time when in production mode, or (2) no user input for the specified amount of time when not in production mode.
SEMI E10/E58 Equipment States FmNT supports the SEMI E10 and E58 specifications, which describe six basic equipment states used to monitor the activity of a machine. FmNT provides the ability to view, change, and record these equipment states. See “E10 Equipment States” in the System Configuration and Setup section. Simplified Setup/Configuration Routines You can access various configuration and setup routines from the FmNT Main Window.

5 Programming Basics and Setup Overview This section introduces the fundamentals of developing dispensing programs in FmNT. These skills prepare you for more complex programming in the next two chapters. The following subsections provide guidance on how programs are built in FmNT and also what tools are used to create them. Read this section before going on to programming. Exercise 5-1, in this section, requires use of the Tutorial Board and FmNT to perform a programming setup procedure.
Program Instructions Programs are composed of command instructions that are executed sequentially. Basically, any function you want performed during a dispensing run should appear as a command at the point in your program when you want the function to execute. Typical programs include both dispensing and maintenance functions. Dispensing functions instruct the Dispensing Head where to move, when to start dispensing, and how much fluid to dispense.
Program Logic and Structure Programming Considerations When creating dispensing programs, your goal should be to maximize production throughput without sacrificing desired quality. Programming should be executed in the most efficient way possible. Limiting the number of times fiducial searches, flow rate measurements, purging, or other processes are performed can increase throughput; however, factors such as fluid type, quality, and repeatability should also be considered.
FmNT Program Structure All FmNT programs consist of a: Pre-Fiducial Block Main Program Workpiece Pattern In addition to the Workpiece Pattern, you may include additional patterns. However, all programs contain the Main Program and Workpiece Pattern at minimum. Pre-Fiducial Block The Pre-Fiducial block is executed prior to the Main Program.
Optional Patterns Instead of including pattern instructions in the Workpiece Pattern, you may create additional patterns and execute or call them from the Workpiece Pattern. For example, if your dispensing program requires a series of dots, you may create a pattern called “Dots” which includes the XY coordinates for the dot dispensing and call the “Dots” pattern from the Workpiece Pattern. Figure 5-1 shows a typical FmNT program structure.
When you access the Programming Window in FmNT, the last saved program opens. 1. To create a new program, select File>New from the menu bar or click on the Program Wizard icon. ! By default, when you create a new program, a Workpiece Pattern opens. See Figure 5-2. 1 2 3 4 Item Description 1 Program Name 2 Fluid Filename 3 Pattern Name 4 Pattern End Command Figure 5-2 Default Programming Window - Workpiece Pattern 2. 5-6 Click on to close the programming window and return to the Main menu.

Programming Setup Programming Setup is a recommended routine to be performed prior to beginning a programming session. Programming setup consists of defining fluid files, setting workpiece alignment options, and teaching workpiece fiducials. " NOTE Before you begin a programming session, it is recommended that you perform a Prompted Setup or Scripted Prompted Setup routine.
Fluid Setup Fluid files record information about the dispensing fluids used in your programs. If all of your dispensing programs use the same fluid, you can attach the same fluid file to all of the programs. However, a different fluid file should be created for each type of fluid used. Fluid files are stored in the Fluid folder under the FmNT root directory as .flu files. If your dispensing system is equipped with a Dual-Action Dispensing Head, you can use the same fluid file for both valves.
3. Enter the fluid name in the Fluid Name textbox. 4. Select the purge parameters that best fit your application and fluid. ! Be sure to consider fluid viscosity and throughput. ! Purge Parameter options are described in Table 5-1. Table 5-1 Purge Parameter Options Command Description Vacuum Shutoff Delay The time (in milliseconds) set for the Purge Station vacuum to turn off after the valve shuts off.
5. Click on the Flow Rate Parameters tab. See Figure 5-8. " NOTE If Variable Valve Speed is enabled, the tab will display a "Valve Speeds" column and "New" and "Remove" buttons.

A flow rate calibration will also be performed on the first board of every run. The timer is reset each time the Run Production Window is opened. On Run Count A Flow Rate Calibration will be performed after completing the number of boards entered in the On Run Count text box.
7. Click on the Pot Life/Low Fluid Check tab. See Figure 5-9 ! Enter the appropriate information regarding fluid pot life and low fluid check options. ! The options on this tab are described in Table 5-3.
Table 5-3 Pot Life/Low Fluid Check Options Command None Description No low fluid check will be performed. Use sensor Uses the installed Low Fluid Sensor to determine when the dispensing fluid is low. Use software tracking Uses the software to determine when dispensing fluid is almost empty based on syringe weight. Enter the appropriate values in the following text boxes. Initial syringe weight When using software tracking, “Initial Syringe Weight” is the weight in milligrams.
8. Click on the Attach Script Files tab (if present). This tab will not appear if you are not using script files for program setup. ! Select the desired Script File categories by clicking the check box to the left of the "Prompted Setup," "Change Syringe," and/or "Low Fluid" button. Categories not selected will use the script files specified in "Setup Script Options" on the Configuration menu. ! Click on the desired category button and select the appropriate script file from the list.
Figure 5-10 Workpiece Alignment Options 2. Indicate the number of fiducials to be used in your program. See “Fiducials” in this section for detailed information. ! If “No Fiducials” is selected, you have the option of confirming the workpiece origin when opening an existing program. To activate this feature, make sure there is a checkmark in the textbox next to “Confirm Origin location when opening an existing program that contains no Workpiece Fiducials.
Teaching Fiducials Fiducials are used to define the position and orientation of the workpiece, or to identify the location of parts on a workpiece. Part of the programming process is to determine which fiducials should be defined to achieve the accuracy and speed required for your dispensing process. Fiducial Detection Methods The Vision System is capable of automatically locating features on the workpiece so that patterns can be placed accurately.
Size The maximum size of the Model Window in FmNT is 256 x 256 pixels (approx. 120 x 120 mils on the part). Fiducials must be smaller than that in order to be used, unless a portion of the fiducial element can be used to represent the whole fiducial. Large fiducials take longer to find. However, if the fiducial is too small, other artifacts or contamination in the Search Window on the workpiece might be misinterpreted as a fiducial.
To Teach a Model Fiducial: 1. In the Main Window, click on Configuration. 2. Select Setup Workpiece Alignment. In the Workpiece Alignment dialog box, select Learn Workpiece Angle first and Two 3. Fiducials. 4. Click on OK. 5. Click on Main in the toolbar to return to the Main Window. 6. In the Main Window, click on Teach a Program. ! The Programming Window opens. 7. Load the Tutorial Board (Side 1) at the mouth of the Conveyor. See Figure 5-12.
10. In the Programming Window, click on File and select New or click on the Program icon. Wizard ! The Create Workpiece dialog box opens. 11. Select Two Fiducials. 12. Click on OK. ! The Teach Window opens asking you to “Teach first point defining axis.” See Figure 5-13.
17. Click on Teach. 18. Click on Done. ! Now you are asked to select the method for defining the first fiducial. 19. Select the Model Finder method. 20. Click on Next. ! Notice the smaller white-lined box in the video display window. This is the Model Window, the area that will be defined as the fiducial. 21. For the first fiducial, use the same dot used to define the workpiece origin. 22. Using the Position Controls, align the camera crosshairs with the center of the dot.
27. Click on the Run Time tab. ! Check for location tolerances means that FmNT will check the found location of the fiducial and compare it to the location where it expected to find it. If the difference between the two locations is greater than the Location Tolerance, FmNT will consider the fiducial to be “Not Found.” ! This ensures that an incorrect fiducial or other feature is not considered to be a correct fiducial, and prevents dispensing on parts that are too far away from their expected locations.
Corner Fiducials In some cases, accuracy is greatly improved by identifying the corner of the part to be dispensed on as a fiducial, especially if there are no good fiducials on the workpiece. Corner Finder is a method to identify fiducials that are part edges or lines or edge pairs, such as the edge of a die. Corner Finder uses a vision tool called a Caliper (see below) designed to find edges or pairs of edges.
The highest contrast transition within the caliper search area is considered to be the part edge, so it is important that the highest contrast edge in the caliper search area be the part edge. Adjust the Search Length, Projection Length and light levels until the most significant transition within the caliper window is the edge of the part.
7. Select Corner Finder. 8. Click on Next. ! Notice the calipers in the video display window. 9. Using the Position Controls, move the Dispensing Head to the lower left-hand corner of Flip Chip 1 on Side 1 of the Tutorial Board. ! Notice the green square in the area below the video display. This is the Quadrant Model, a representation of the part onto which you will dispense. The highlighted corner of the quadrant should be the same corner where the fiducial will be taught. 10.

6 Beginning Programming Overview This section introduces you to the fundamental dispensing commands that form the foundation for all dispensing applications. You will learn how to create a basic dispensing program using all of the basic dispensing elements. It is essential for you to develop the basic programming skills in this section. These skills will be further developed in the Advanced Programming section.
Creating a Program 1. Select Teach a Program from the Main Menu. ! The Programming Window opens. The last saved program will appear in the Programming Window. 2. To create a new program, select File>New from the menu bar or click on the Program Wizard icon on the toolbar. ! The Programming Window shown in Figure 6-1 opens. Notice that, by default, the Workpiece pattern opens. Pattern Name Program Name Fluid File Pattern End Instruction Figure 6-1 Programming Window " 3.
Dispensing Commands Dispensing commands dictate the actions to be performed. They may consist of maintenance functions as well as dispensing instructions. Each command has a line number and is executed sequentially. You may rearrange program commands by cutting and pasting them. Ultimately, you want to program the workpiece so that the commands are executed in the fastest way possible. To enter a dispensing command, click on the appropriate icon on the Program Commands toolbar, shown in Figure 6-2.
Dispensing Elements There are several fundamental dispensing elements and patterns that form the foundation for all dispensing applications. These include: Dots Arcs Rectangles Area Fill Weight Control Lines Find Substrate Height Select Valve Coat Dot Coat Grid Lines Circles Pots Spiral Fill Weight Control Fill Pattern Multipass Coat Line Dot Grid When you select Dispensing Elements from the Program Commands Toolbar, a Teach Window opens.
Dot FmNT is capable of dispensing precision dots quickly and uniformly. Dots are used in a variety of dispensing applications, including Surface Mount Adhesive (SMA) applications. The size of the dots and characteristics of the dispensing are controlled through Dot Parameters. Refer to “Dot Parameters” later in this section. Line Lines are a common dispensing element for Dam and Fill and Flip Chip Underfill applications. To program a line, you simply teach the start and end points of the line.
Rectangles Rectangles are commonly used in Dam and Fill applications. A quick-drying, high-viscosity fluid is used for the rectangle to form a perimeter dam. A lower viscosity adhesive is generally used for the fill. To program a rectangle, you are required to teach the opposite corners. Pots Potting (Weight Control Dots) is a technique used to fill cavities or to dispense multi-height shapes.
Coat Dot Coat Dot is used to dispense a single shot (i.e., a dot pattern) of flux material followed by a short burst of air. This instruction is available only when one or both of the configured valves is a Flux Jet. Coat Line Coat Line is used to dispense flux material along a straight path (i.e., a line pattern). This instruction is available only when one or both of the configured valves is a Flux Jet. Coat Grid Coat Grid is used to dispense a grid (in XY) of flux lines.
Process Commands When you click on the Process button, a drop-down menu opens containing the available process commands. When you select a process command, it is inserted into your dispensing program at the cursor position. Process commands are described in Table 6-1. Table 6-1 Process Commands Command 6-8 Description Find Substrate Height Determines workpiece height. Purge Inserts a purge command into a program. Measure Flow Rate Inserts a Measure Flow Rate command into a program.
Procedure Clicking the Procedure button opens a dialog box, which allows you to create a procedure. A procedure is a series of commands. The commands generally contain setup and maintenance functions. No dispensing or fiducial instructions can performed in a procedure. The procedure can then be executed from your program by inserting a call instruction. Once a procedure has been created, it can be used in multiple programs.

Dot Parameters You can control the size and accuracy of dot dispensing by experimenting with dot parameters. You can also change Dispensing Head behavior and valve time to ensure clean dispensing. The Dot Parameters are divided into four categories according to when each parameter is implemented during the dispensing process. The categories are: Pre-Dispense During Dispense, Post Dispense Advanced You may define up to ten different dot styles in FmNT. Each style may have different parameters.
Dispense Gap The Dispense Gap is the distance between the substrate you are dispensing on and the needle tip during dispensing. This distance is one of the more common adjustments to optimize dispensing programs. The units are in inches. Typically, the Dispense Gap is set to half the dot diameter. Number of Shots This parameter controls how many shots of fluid will be dispensed at a single location. When making larger dots, it is desirable to move the needle up between shots at the same location.
Suckback At the end of dispensing a line or a dot, the valve is reversed for the Suckback period to remove any material from the tip of the needle. The Suckback value should be set according to fluid viscosity. Generally, 10 ms (0.010 sec) is sufficient. Advanced Dot Parameters Mid-Move 1 and Mid-Move 2 These parameters are advanced dot parameters used for special applications and testing. For more information, contact Asymtek Application Engineering.

Watch to see the dots dispensed. ! You should notice a difference in the size of the Type 1 and Type 2 dots. ! Examine the board for quality and accuracy.
Line Parameters Line Parameters offer greater control over line thickness and ensure cleanly dispensed lines. Line Parameters are divided into three categories according to when each parameter is implemented during the dispensing process. The categories are: Pre-Dispense During Dispense Post Dispense You may define up to ten different line styles in FmNT. Each style may have different parameters. You may set line parameters for lines, weight control lines, arcs, circles, rectangles, and area fills.
Suckback At the end of dispensing a line or a dot, the valve is reversed for the Suckback period to remove any material from the tip of the needle. The Suckback value should be set according to fluid viscosity. Generally, 10 ms (0.010 seconds) is sufficient. Dwell The Dwell is how long the Dispensing Head stays at the final position of a move before retracting. This allows residual fluid to detach from the needle tip before the Dispensing Head moves to the next location. The units are seconds.
Retract Speed This is the speed of the Dispensing Head while moving the Retract Distance. The units are in inches/second. Typically, 2 in/sec is sufficient. Retract Acceleration This is the parameter that controls how fast the Dispensing Head comes up to the Retract Speed. You may need to set this high for small dispensing moves. The units are inches/second2. Typically, 300 in/sec2 is sufficient. Jetted Line Parameters Jetted lines are those dispensed with a DispenseJet valve.

Flow Rate Calibration When dispensing weight control lines and dots (pots), it is necessary to perform a Flow Rate Calibration, also referred to as Mass Flow Calibration (MFC). Flow Rate Calibration is a weight measurement system that is used to calibrate the weight of fluid dispensed at given times and automatically adjust the flow rate if needed. It is particularly useful as the viscosity of the fluid changes due to heat, time, and curing. Valve Speed Flow Rate is a function of valve speed.
X-1000 Dispensing Systems Only Figure 6-16 Valve Settings Dialog Box 4. Enter the desired valve speed. ! Higher values result in faster motor speed. Lower values result in slower motor speed. 5. Click OK. " NOTE On dispensing systems with software controls for valve speed, the Set Speed button will be functional. Click on Set Speed to open a dialog box for establishing valve speed during the Measure Flow Rate process.
Dispensed Weight Bias Dispensed Weight Bias is generally used with Weight Control Lines. If the weighed fluid is consistently over or under the desired percentage of fluid after a flow rate calibration, you can set the bias to compensate for the variation. Bias is necessary to ensure consistent fluid dispensing. When creating a dispensing program, typically several samples of a dispensed pattern are weighed to make sure that the proper amount of fluid is being dispensed.

7 Advanced Programming Overview This section discusses and demonstrates some of the more advanced techniques for perfecting your dispensing programs, including: • Creating and Placing Patterns • Multipass Patterns • Step and Repeat • Variable Valve Speed • Jet on the Fly • Dynamic Dispense Control " NOTE You should complete the Programming Basics and Setup and Beginning Programming sections before attempting the exercises in this section.
Creating and Placing Patterns Creating a Pattern Patterns are essential building blocks of complex dispensing programs. A pattern is a sequence of related instructions that are grouped together and saved as a single unit. All FmNT programs include a Workpiece Pattern, which can contain all of the instructions needed to dispense an entire workpiece. However, to add flexibility and reduce the number of programming instructions, you have the option to create additional patterns.
To create a pattern: 1. button on the Program Commands toolbar. See Figure 7-2. Click on the Pattern Figure 7-2 Creating a Pattern 2. Select Create Pattern. ! The Create Pattern Dialog Box will open. See Figure 7-3. Figure 7-3 Create Pattern Dialog Box 3. Enter a name for the new pattern. 4. Select the fiducial setup alignment that best fits your pattern type. 5. If your pattern contains Skip Marks, activate the Use Pattern Skip Mark feature. " 6.
Placing a Pattern Once the pattern has been created, its location on the workpiece must be defined. Placing a pattern is the process of defining the pattern locations (placement points) on the workpiece in relation to the workpiece pattern origin. You can place the same pattern at different locations on a workpiece by teaching two or more pattern placement points for the pattern. For example in Figure 7-4, the Chip Pattern is placed in three different locations on the workpiece.
To place a pattern: 1. Click on the Pattern 2. Select Place Pattern. button on the Program Commands toolbar. See Figure 7-2. ! The dialog box shown in Figure 7-5 opens. 3. Select a pattern from the list in the Available Patterns textbox. ! A Teach Window will open prompting you to define the pattern origin. Figure 7-5 Placing a Pattern Teach Window " NOTE Advanced Programming See Exercise 7-1 for step-by-step instructions on creating and placing a pattern.
Skip Marks When you create a pattern in FmNT, there is an option called Skip Marks that can be activated and used for the new pattern. Refer to Figure 7-3. Skip marks are specialized fiducials and can greatly increase throughput in applications that require the same pattern to be placed in multiple locations on one board. Skip marks are taught exactly like fiducials.
Exercise 7-1: Creating and Placing a Pattern 1. Perform the Programming Setup procedure described in the Programming Basics and Setup section. 2. Load Side 2 of the Tutorial Board and define workpiece alignment, origin, and fiducials. " 3. NOTE Refer the Programming Basics and Setup section for instructions on programming setup and fiducials. Select Teach a Program from the Main Menu. ! The Programming Window opens. 4. Select File>New from the menu bar or click the Program Wizard new program. 5.
10. Click on Teach. 11. Click on Done. ! The Teach Window changes asking you to select a method for defining a fiducial. 12. Select Corner Finder and click on Next. 13. Use the Position Controls to center the camera crosshairs on the ULHC of the first square in the top row on Side 2 of the Tutorial Board. ! Notice the Quadrant Model, the green square in the area below the video display. The ULHC of the Quadrant should be highlighted to indicate that this is the corner you are going to teach.
20. Click on Dispensing Elements in the Program Commands toolbar. 21. Click on Weight Control Line. 22. In the weight text box, type 20 and choose Type 2 for the Line Style. 23.

Select Run>Dry Run from the menu bar. 45. Watch to make sure that the program goes through the following steps: a. Locate Workpiece Fiducials. b. Locate Fiducials for each of the squares along the top row. c. Dry dispense L-shaped line around each square.
Multipass Patterns A multipass pattern is a pattern that reuses one set of fiducials to repeat the same pattern at one or more locations on the workpiece. This is a helpful feature when an application requires multiple dispenses or requires a "seal run" after adhesion. One big advantage of multipass patterns is that once the substrate height has been found and the fiducials defined, the information is reused for all of the passes, which can greatly increase throughput.
Multipass Timer You also have the option to set timers during the dispensing process. For example, you may want to make sure the fluid flows completely underneath the chip before the sealant is dispensed. • Await Multipass Timer - Await Multipass Timer should be the first command in every Pass of a multipass pattern, except for the first pass. Await Multipass Timer works in conjunction with Reset Multipass Timer. • Wait Time - Enter the number of seconds you want to wait between passes.
Underfill Patterns One application that typically uses the multipass feature is underfill. There are several types of line patterns used for underfill applications. Two common types are L-shaped and U-shaped patterns as shown in Figure 7-10. Variations of these types of underfill patterns are used as well. These patterns and processes are designed to assure complete underfilling without excess and to prevent voids in the underfill.
Chip Offset Chip Offset is the distance between the edge of the part (usually a die) and the edge of the dispensing needle and is primarily used for underfill applications. It is defined to ensure that the needle does not chip the die edge during dispensing. The Chip Offset is used in the X-axis and the Y-axis as shown in Figure 7-11. A formula is used to calculate the Chip Offset: Chip Offset = ½dn + 7 mil where dn is the outer diameter of the needle Reticles can also be used to provide the Chip Offset.
Exercise 7-2: Advanced Underfill Workpiece " NOTE In this exercise, you will learn how to program an entire underfill workpiece. First you will program the L-shaped pattern and then you will program a Ushaped multipass pattern. You will learn when to insert timer commands, height sense commands, flowrate measurements, use skip marks, and reuse fiducials. To program the L-shaped underfill pattern: 1. Perform the Programming Setup procedure described in the Programming Basics and Setup section. 2.

Variable Valve Speed Variable Valve Speed (VVS) is a new technology available with FmNT 4.5 and above that allows the programming of multiple material flow rates per board without necessitating dual valves. Variable Valve Speed has proven to significantly reduce cycle time by optimizing each dispense pass for an optimum line speed without compromising quality or repeatability.
With Variable Valve Speed, the ability to shift to a faster flowrate reduces the dispense time to 1.5 seconds (0.5 seconds for the fill and 1 second for the pass) because the fill flowrate is not limited to the maximum flowrate of 30 mg/sec for the seal pass. Fill - 50 mg Seal - 30 mg Total 80 mg 1 in2 Fixed Speed Process Weight Distance Variable Valve Speed Flowrate Calculated Line Speed Time Elapsed Flowrate Calculated Line Speed Time Elapsed Fill 50 mg 1 inch 30 mg/s 0.6 in/sec 1.

Jet on the Fly “Jet on the Fly” (JOF) technology is Asymtek’s fastest jetting method. With “Jet on the Fly” technology, the DispenseJet pump can dispense lines of dots “on the fly” (without stopping). Unlike traditional “Stop and Shoot” methods, lines are formed by shooting a series of dots without stopping at each dot position. Excellent results have been obtained jetting small-die underfill, no-flow underfill, and die attach patterns.
Position-Based Spacing Control Mode In the Position-Based Spacing Control Mode, the valve fires at predetermined XY positions along the line. Spacing – The value designates the distance between the center of one dot and the center of the next dot. Break Start Point -When used in Position Based Spacing Control Mode, the Break Start Point determines the distance from the beginning of the dispensed line to the point along the line where no dispensing will begin.
Total Number of Dots Control Mode In the Total Number of Dots Control Mode, the valve will dispense a set number of dots for a particular line. • Total # of Dots – This value determines the total number of dots to be dispensed along the length of the line. No Dispensing Control Mode In the No Dispensing Control Mode, the valve is turned off along the line; generally used in continuous path methods.
