> What's people's experience with SMT connectors? I've used some of each. The pure surface mount ones are more likely to break off the pcb if stressed. For external connectors, like AC jacks, I/O connectors, I would recommend paying the extra assembly cost for through hole, for mechanical reasons. On board-to-board or internal wiring harnesses, we've had OK luck with SMT connectors. The fine pitch ones are a problem because of fine pitch, not because of being SMT, that is, they are susceptable to shorts in soldering. As with SOICs, the right board layout and especially solder mask are very important. ------------ Barry King, KA1NLH Engineering Manager NRG Systems "Measuring the Wind's Energy" Hinesburg, Vermont, USA www.nrgsystems.com
