Technetter's, I have a question about immersion gold plating vrs HASL on thru hole boards to be wave soldered. We are currently using HASL and considering switching. Is there any difference to be expected in top side wetting of gold vrs HASL? Also, is there any significant difference in appearance between top side and bottom side solder fillet when using gold immersion? Are their any other issues? ################################################################ 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.
