Hi all, Which IPC document spells out soldermask surface finishes like glossy, semi-matte or matte? IPC-SM-840 does not mention any spec's about soldermask surface finishes. How do PCB vendors create matte surface finish? Is there any industry standard I can use when specifying a soldermask surface finish like matte? I am used to seeing glossy soldermask finish. What are process/manufacturing issues for using matte soldermask finish ? Thanks Matthew P. --------------------------------------------------- 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 847-615-7100 ext.2815 -----------------------------------------------------
