ERIC, I'D LIKE TO SUGGEST A FEW THINGS TO YOU. 1. IPC-D-275 IS A GOOD PLACE TO START FOR COST REDUCING A PWB DESIGN. ON PAGE ONE OF THE STANDARD THEY IDENTIFY BOARD TYPE, BOARD CLASS, AND BOARD PRODUCIBILITY LEVEL. ONCE YOU'VE CATATGORIZED YOUR DESIGN USING THESE IDENTIFIERS YOU CAN SIFT THROUGH THE REST OF THE DOUCUMENT AND CULL OUT WHAT APPLIES TO YOU. 2. IPC-A-610 IS A SOURCE OF INFORMATION ON PWA ISSUES, IT ALSO HAS SOME INFORMATION WHICH MIGHT BE BETTER PLACED IN IPC-D-275. 3. INSTEAD OF TALKING TO NO PWB SHOPS, FOR FEAR OF BIASING THE OUT-COME, TALK TO AS MANY AS POSSIBLE. YOU'LL BEGIN TO NOTICE SIMILLARITIES AND/OR DISTINCTLY DIFFERENT WAYS OF ACCOMPLISHING THE SAME END.

I work for Mutoh America and am new to the PCB world. I'm looking for standard off the shelf parts and processes. The information that I am looking for should contain substrate material types and their reletive cost differences (percentages only) and characteristics, sokdermask, hole size, density level of copper from one board edge to the other, etc. I'm trying not to talk to PCB shops so that I amy get an unbiased opinion and know what is possible in this industry. I'm finding this to be a difficult task. Do you have any suggestions on were I can obtain this type of information? Thank you, Eric Reno ------> [log in to unmask] Mutoh America, Inc. 3007 E.
