Can someone help with the processing of a heavily populated SM PCB, SM top and bottom which has to be reflowed both sides and has through holes parts ( no wave solder ). Any guidelines on how this should be processed would be of great help ie what side is the high temp solder used on, most densly least densly populated etc etc. Regards, ken Robertson Telspec ################################################################ TechNet E-Mail Forum 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's web site (http://www.ipc.org) "On-Line Services" section for additional information.
