Technetters, I have a question regarding soldermask web surrounding fine pitch components pads/leads. In our current fabs, we are finding that not all 20 mil pitch components leads had soldermask web so we have decided to provide soldermask layer with 1:1 opening for pad, without any clearance. I am expecting that fab house will provide some solder mask clearance to prevent solder mask running over the pads along with soldermask web surrounding fine pitch leads. Please let me know if it is good idea or not with pros and cons. re, ken patel ______________________________________________________ Ken Patel Phone: (408) 490-6804 1708 McCarthy Blvd. Fax: (408) 490-6859 Milpitas, CA 95035 Beeper: (888) 769-1808 ################################################################ 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.
