Further to my last note. We apply our own peelable mask via a screen printing process just prior to stuffing the PCB because we also found that mask applied by the manufacturer sometime before actual use (ie 6-8 weeks due to our sea freight and stock holding) made it very hard to remove. Vacuum packaging of the PCB's did help a lot, but we decided to do our own thing for flexibility and ultimate ease of removal reasons. ---------------------------------------------------- Dave Elder ([log in to unmask]) Tait Electronics Ltd, Christchurch, New Zealand Tel: (64) 3 358-0327, Fax: (64) 3 359-4632 ################################################################ 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.
