So, since we are speaking of a vacuum deposition process, a Blonde was asked if she were in a vacuum, would she be able to hear. Is it on or off was her reply. May I please have a copy of that data?

Paralene, when applied over some no-clean wave-soldering and solder paste flux residiues, does not provide good protection. I miss Al Schneider. Karen Tellefsen - Electrical Testing [log in to unmask] 908-791-3069 So are you telling us not to use Al Schneider or no-clean soldering materials?

Karen Tellefsen - Electrical Testing [log in to unmask] 908-791-3069 Mary Lou Sachenik Subject 05/09/2009 07:59 [TN] Parylene Adhesion Tape Test AM Please respond to TechNet E-Mail Forum <[log in to unmask]> OM> We recently had some issues with lack of adhesion of Parylene coating What types of notes are being used on drawings to define parylene conformal coating adhesion test on pwa's? Is the ASTM3359-08 (for assessing the adhesion of coating films to metallic substrates) the best spec to call out for this testing . I presently don't have pwb coupons to perform destructive cross hatch test. What type of tape is being used testing parylene adhesion on the PWA's? Some specs call out 3M-250 tape, the ASTM D 3359 calls out the Permacel 99. Actually I prefer the Wescorp 79210 clear Anti-static Tape, does this seem acceptable? --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 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 or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 ----------------------------------------------------- --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 15.0 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 or (re-start) delivery of Technet send e-mail to [log in to unmask]: SET Technet NOMAIL or (MAIL) To receive ONE mailing per day of all the posts: send e-mail to [log in to unmask]: SET Technet Digest Search the archives of previous posts at: http://listserv.ipc.org/archives Please visit IPC web site http://www.ipc.org/contentpage.asp?Pageid=4.3.16 for additional information, or contact Keach Sasamori at [log in to unmask] or 847-615-7100 ext.2815 -----------------------------------------------------
