Transition Socket Specification INTRODUCTION Transition sockets are products that allow header boards (for next generation in-circuit emulators or in-circuit debuggers) or device adapters (for the MPLAB ICE 2000 in-circuit emulator) to interface to sockets on target applications. Typically, header boards or device adapters have connectors that match development cycle device formats, such as DIP or PLCC. However, target sockets will match compact production device formats, such as SOIC, SSOP, QFP, or QFN.

Transition Socket Specification TRANSITION SOCKET APPLICATIONS – COMMENTS AND SUGGESTIONS GLOSSARY Attention to component placement should be considered in mating the adapter sockets to the SOIC/SSOP headers. DIP – Dual In-line Package The placement of vias around the Surface Mount Technology (SMT) layout area should be examined. Vias immediately adjacent to the end of a SMT pad may inadvertently come into contact with the header leads.

Transition Socket Specification RECOMMENDED INSTALLATION OF TRANSITION SOCKETS WITH CABLES 3. 4. 5. For transition sockets that use a cable, follow these instructions for installing your transition socket on the target board. Center each cable on the footprint (see below). Tape down each cable to prevent movement. Solder each lead to target pad.

Transition Socket Specification XLT20QFN-1 Soldering Suggestions This socket is difficult to solder since the device pins are not exposed, but embedded, into the socket’s Surface Foot (SF). 1. 2. 3. 4. 5. To start, add tack flux to the target land pattern. Visually align the QFN SF with the target land pattern. Then solder two opposite SF pins to the target lands so that the SF does not move around. Finish soldering the rest of the SF pins.
