A surface mount base provides access for other accessories. A SMT base replaces the component on the target card pads providing pins that mate with ZIF socket adapters, emulator adapters, logic analyzer adapters, SMT component tops, emulator extension cables, et cetera.

Installation is the same as other surface mount devices, and infrared and hot air procedures are recommended. Hand soldering is also a viable alternative for a skilled technician. Hand soldering procedure Soldering Bases.pdf
