4 Configuration and Characterization 4.1 Overview Your dispensing system is configured at the Asymtek factory prior to shipping. However, if any components have been changed or moved, it may be necessary to reconfigure them in ECNT. This section contains the following procedures: • • • • 4.
4.4 Tool Configuration A tool consists of a Fluid Dispensing Applicator and nozzle. The Tool Configuration dialog box allows you to set the offset for each tool and perform a characterization. 4.4.1 Tool Offset Tool Offset is the X, Y, and Z distance from the lower tooling pin on the Z slide (also called the tool flange, or tool arm) to the tool tip (end of nozzle). See Figure 4-1.
To define Tool Offsets: WARNING! If Tool Offsets have already been defined and set up in the Tool Library, correct offsets are displayed in the Tool Configuration dialog box. DO NOT change them without assistance from your Asymtek representative. Your Asymtek representative can supply you with the offset coordinates for each tool used. 1. Click on Configure > Tools from the Edit Screen menu bar. ! The Tool Configuration dialog box opens. See Figure 4-2. Figure 4-2 Tool Configuration Dialog Box 2.
4.5 " Characterization NOTE A characterization must be performed for each tool and each coating material used or as required to ensure quality and consistent dispensing. Many variables, such as material type, temperature, viscosity, substrate type, robot velocities, and dispenser response times affect the coating process. Characterization improves coating placement accuracy and repeatability. The Characterization Wizard helps you adjust program values to compensate for these variables.
2. Click Clear Positions. ! If you have performed a characterization before, the old test area coordinates are used unless you clear them. 3. Click Next. 4. Teach the substrate height. a. Place a characterization sheet in the workcell. See Figure 4-4. b. Install a nozzle on the Fluid Dispensing Applicator and lower the tool until the tip just touches the characterization sheet (substrate).

6 Troubleshooting 6.1 Overview If you have difficulty running your coating programs, use this section to identify a possible solution to the problem. If you have difficulties not listed in this section, or the suggested solution does not correct the problem, contact Asymtek Technical Support. This section covers the following topics: 6.
6.3 " Programming Errors NOTE 6.3.1 Most errors usually take place during programming, with the exception of Conveyor errors and possibly Fan Width Control errors. Program Does Not Run With the Edit Screen open, an error will cause a dialog box to display “Program had Error.” See Figure 6-3. In most cases ECNT will toggle to the procedure or pattern with the error and will mark the instruction that caused the error with a blue arrow.
6.3.2.2 Not Found Errors If ECNT fails to find a procedure or pattern, it displays an error message that includes the name of the procedure or pattern not found. This error message occurs: • If the procedure called by a Call Procedure instruction is not in the loaded macro program. • If a Place Pattern or Call Procedure instruction was not included in a pattern or procedure. • If a Place Pattern or Call Procedure instruction was inserted without selecting a pattern or procedure to place or call.
6.4 GoTo Errors If the applicator will not perform a GoTo command: 1. Check the system Safe Z Height (Utilities > Robot). The system Safe Z Height is used before executing anything while in the Edit Screen. The Safe Z Height value in most configurations will be a negative number. 2. Check to make sure the Tool Flange is not selected in the Current Tool Selector. The Tool Flange is the Tool 0,0,0. If it is, select another tool, then click GoTo again. 3.
6.7 Fan Width Control Errors The Fan Width control option has sensors that detect and measure the fan pattern and fluid pressure controls to adjust fan width to keep it within programmed tolerances. The fan width instructions can be included in procedures or programs to periodically measure and control the fan width. Fan width tolerances are set by the programmer with Error and Warning offsets during the Fan Width configuration procedure (Configure > Fan Width Setup).
Appendix A Instruction Quick Reference Overview This appendix provides a brief description of all ECNT program instructions grouped by category. Refer to Appendix B for detailed information on program instructions, instruction properties, and syntax. Tab A-201 Conveyor Conformal Coating Button Instruction Description Send ACL Sends an ACL command to the Conveyor Controller. Coat Specifies a single coating pass, in a straight line. Begin and end coordinates must be specified.
Tab Fan Width Control Button Instruction Description Pattern Array Repeatedly places a pattern on a rectangular grid. This is useful for coating boards that are panelized or palletized with many boards on a single panel or pallet. Fan Width Measures and controls fan pattern width. This instruction should only be included in a Periodic procedure in a macro program.
Tab Button Instruction Description Add Fault Use this instruction to add a clearable fault message to the operator display. This instruction is typically used in user-created error handling procedures, which have no pre-programmed fault messages. The message will appear in the Event Monitor and Fault Monitor. Move Relative Motion Moves the tool the specified X, Y, and Z distances from current position. Move Tool Moves a specified tool to a specified position.
Appendix B Instruction Properties Overview This appendix alphabetically lists all ECNT program instructions, descriptions, syntax (if applicable) and instruction properties. Abort Program Description: Ends program with error (returns False to Robot Controller). If this instruction is executed during production, production will be stopped with a "Coating program had error" message. Properties: Property Log Message Description Enter the text message to appear in the Log.
Property Description Begin Y Y coordinate where dispensing begins. End X X coordinate where dispensing ends. End Y Y coordinate where dispensing ends. Midpoint X X coordinate that determines radius of arc. Midpoint Y Y coordinate that determines radius of arc. Depart Height Depart end motion position with tool tip no lower than this height. If Depart Height is greater than dispense height, then tool tip is moved to Depart Height after dispensing is completed.
Property Description Depart Height Depart end motion position with tool tip no lower than this height. If Depart Height is greater than dispense height, then tool tip is moved to Depart Height after dispensing is completed. Use to avoid collisions with components on board. Dispense Height Distance from tool tip to substrate while dispensing.
Property Description Depart Height Default = None. Depart end motion position no lower than this height. If value is set to None or less than Dispense Height, it is ignored. Use to avoid collisions with components on board. Dispense Height Default = Height determined while running characterization for tool selected for this instruction. Distance from tool tip to substrate while dispensing.
Check Needle Description: Checks if a needle has moved. This could be in a periodic procedure to detect collisions with out-of-place components or improperly loaded boards. Properties: Property Description Error Procedure Name Name of the procedure to call if the preset error tolerance is exceeded. Click on the List button in the property field to select from a list of the procedures in the currently loaded programs.
Property Description End Y Y coordinate where dispensing ends. Ignore Masks Default = False (No). If True (Yes), then material dispensed even if specified coordinates fall within a Mask Region.

Start Distance Default = Automatic. Distance to accelerate after dispensing.
End Flow Measurement Description: This instruction stops measuring the flow of coating through the flowmeter, and checks the flowmeter counts against the minimum and maximum volume property settings. This instruction is only available if the flowmeter option is installed in the fluid system and configured in ECNT. The amount dispensed is logged and also stored in the production database, which can be accessed from View > Data > Flow Monitoring.
Fan Width Description: Measures and controls fan pattern width. Because this process takes time, this instruction should only be included in a Periodic procedure in a macro program. A faster alternative is the Fan Quick Check instruction. Properties: Property Control Width Description Default = True. If set to True, the fan width is measured and controlled by adjustments to fluid pressure. Warning or error messages are only be generated if fan width cannot be adjusted to within tolerances.
Find Needle Description: Updates the offsets of a needle. This would normally be done after a needle change so ECNT can learn the position of the new needle. Properties: Property Description Error Procedure Name Name of the procedure to call if the preset error tolerance is exceeded. Click on the List button in the property field to select from a list of the procedures in the currently loaded programs.
Log Message Description: Allows programmer to send a message to the log file when a specified event occurs. May be used to log product completion times to evaluate production timing and lapse times.

If set to False, begin each pass (across row or column) on same side of grid. X Placement X coordinates of first pattern placement. Y Placement Y coordinates of first pattern placement. Z Placement Z coordinates of first pattern placement. Pause Description: Allows the programmer to pause a program and display a message on the screen while waiting for user input.
Prompted Log Description: Allows programmer to stop production and request that the operator enter a message. This message is written to the log file and displayed in the Event Monitor, just like a regular log message. The request is displayed as a dialog box, with OK and Cancel buttons. For example, if you want the operator to enter the serial number of each board coated, create a Prompted Log instruction as the first instruction in Main.
Rotate Tool Description: Rotates the tool in 90-degree increments. Only supported by the Select Coat 4 or 5-Axis dispenser. Properties: Property Description Rotate (deg) Number of degrees to rotate the tool. Rotation is in 90-degree increments. If a value less than 90 but greater than 45 is entered, the tool is rotated 90 degrees. If a value less than 45 degrees is entered, the tool is not rotated. The rotate cycle is absolute, not relative.
Set Outputs Description: Sets digital outputs. Properties: Property Outputs Description Output number and condition setting. Positive = True, Negative = False. A More button appears in the property field. Clicking on this button displays the Set Outputs Conditional Edit dialog box for the instruction.
