I am looking for some help concerning solder spatter. I manufacture ceramic hybrids that have gold plated terminal blocks (50 mil square) placed near the edge of the hybrid. We contiually see solder spatter randomly located on the top of the blocks at at yield hit of anywhere from 2 to 30 percent. We have set our oven profile such that there is the minimum amount of preheat ramp, and we reflow in air. Could anyone provide some help on how to deal with this? Any good resources for information, abstracts, etc. that would help out? --------------------------------------------------------------------------------- Technet Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF Technet To temporarily halt delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search previous postings at: www.ipc.org > On-Line Resources & Databases > E-mail Archives Please visit IPC web site http://www.ipc.org/html/forum.htm for additional information, or contact Keach Sasamori at [log in to unmask] or 847-509-9700 ext.5315 ---------------------------------------------------------------------------------
