Fab experts, After getting few responses on my previous email on via plugging, I was surprise to find one response saying that plugging of the via is not going to fill the via complete but it will rather be towards the side it applied. So, the question is that then there is a possibility of chemical entrapment from the other side so do I have to tell the fab house to plug it from both sides? re, ken patel --------------------------------------------------------------------------------- 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 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 ---------------------------------------------------------------------------------
