We have an application where we would like to assemble a 0.185" thick PWB with through hole relay components that have a 0.018" pin diameter. The through holes on the PWB have a 0.037" finished diameter..... Are there tricks to wave soldering a board this thick? If wave soldering is not an option and neither is hand soldering, has any one tried paste in hole in such thick boards? We have done PIH in the past, but they were on 0.062" thick PWBs.... Any suggestions? marcelo ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
