Intel Pentium 4 Processor 423 Pin Socket (PGA423) Design Guidelines

423 Pin Socket Design Guidelines

3.3. Materials:

3.3.1. Socket Housing:

Liquid Crystal Polymer (LCP), UL 94V-0, or equivalent. Flame rating,

temperature rating and design capable of withstanding reflow solder process

per Section 5.8.

3.3.2. Color:

The 423 Pin Socket will have uniform color. The color requirement does not

apply to the actuation lever arm.

3.3.3. Markings:

3.3.3.1. Name:

423 Pin Socket

(Font type is Helvetica - 16 point Bold).

This mark shall be molded or laser marked into the top of the cam

housing.

Manufacturer’s insignia (font size at supplier’s discretion).

This mark shall be molded or laser marked into the socket housing.

Both marks must be visible when first seated in the motherboard. The

marks must pass the reflow solder process of Section 5.8 and the

solvent resistance test in Section 5.11. Any requests for variation

from this marking requires a written description (detailing size and

location) to be provided to Intel for approval.

3.3.3.2. Lot Traceability:

Each socket will be marked with lot identification code that will allow

traceability of all components, date of manufacture (year and week),

and assembly location. This mark can be an ink mark or a laser mark

but must be able to withstand a temperature of 225°C for 40s

(minimum) per Section 5.8 and must pass the solvent resistance test in

Section 5.11. The mark must be placed on a surface that is visible

when mounted on a printed circuit board. In addition, this

identification code must be marked on the exterior of the box in

which the units ship.

3.3.3.3. Socket Size:

The 423 Pin Socket must fit within 2.400in x 2.990in x 0.230in,

allowing full insertion of the pins in the socket, without interference
