Fellow techs, I have been asked to recommend the type of pwb plating that is best for a simple board with only a few components. The finest pitch component is a QFN, 64 pads, 0.5 mm pitch. There are some 0402 resistors and capacitors as well. My 2 choices are HASL or ENIG. Would someone please comment on which is best for 0402 and 0.5 mm QFN type components. Thanks in advance. joe --------------------------------------------------- Technet Mail List provided as a service by IPC using LISTSERV 1.8e 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 847-509-9700 ext.5315 -----------------------------------------------------
