PIN GRID ARRAY SOCKETS Optional Tabs for Clip-on Heatsink** Interstitial Pattern Series 518 * Series 518 Interstitial PGA sockets are available with and without tabs for clip-on heatsinks. * Mill-Max #43, "Ultra-Lite" contact standard, see page 209 for details. * Hi-Temp PCT polyester insulator material suitable for all forms of soldering. * A pry-bar tool is available for extraction (part # 828-01-010). SOLDER TAIL SOCKET PIN (Without Heatsink Tabs) Ordering Information Interstitial configurations are a .100" grid pattern overlapped with a second, staggered .100" grid pattern thus doubling the package density of the socket. 1. Locate interstitial footprint pattern from pages 107 to 111, the middle 8 digits of the part number will be located under the pattern. 2. Specify 2-digit plating code from chart at bottom of page. 3. Determine the last 2 digits of part number from the pin type at left. For sockets with heatsink tabs, see chart "A" below for pin options.
