I've been having ISP problems. Verizon. Need I say more? Anyway, I think they are fixed, courtesy of addr.com.

Since warpage is "well within IPC recommendations" [presumably for a maximum warpage specification], the most significant problem here is the design of the rack into which the boards fit; it was clearly not designed to handle normal PC boards. One more comment: if one uses a single supplier for fabrication and assembly, one can make any specification whatever for warp on the final board (including residual changes in warp after soldering), and it will be the responsibility of the fabricator/assembler to make it work. If they can't do it, it would be, again, their responsibility to tell you that in advance. To avoid getting into a major hassle, it would be wise to make the warpage requirement, and that it is tighter than the IPC standard, obvious and crystal clear in the purchase order/supplied specifications and files. Of course, fabrication outside the norms can have a major impact on cost; thus fixing the rack might well be the most economical procedure. Do the racks meet their specification? If not, the manufacturer would be presumably be responsible for replacing them.... * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/[email protected] * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
