Black pad defect on gold plated boards

Electronics Forum | Thu Aug 21 22:10:07 EDT 2003 | adlsmt

Well, for some reason the board house will pay for the boards but has some issue with paying for the parts on them. Why am I not supprised? Perhaps I have mis-diagnosed the problem. We have found two different board p/n's with the same type of defec

Wow, You're breaking into some fun stuff. Holding WIP is expensive, ineffective, and typically gives you more quality headaches than you know what to do with. What are you going to do with your partially built up boards? Are you going to hand sold

Hi Patrick, I can easily troubleshoot ML, EL and SL 20 systems by phone or e-mail, but the MPC-29 is a bit more complex. The problem that you are describing was failry common, and there were a number of potential causes. First is to check if the dr

As someone who has worked for a contract manufacturer in China, I can tell you that regaining manufacturing jobs in the US will be a difficult task. Difficult, but not impossible. Many companies are discovering that manufacturing has only ONE advanta

I used to work for a multi-billion, multi-national Contract Manufacturer. I quoted manufacturing (RFQ) for my US site. My counter parts in Beijing were comparison quoting for 1/10 to 1/15 below my quotes. I can't tell you how many builds we did on

Dream SMT Line

Electronics Forum | Tue May 04 15:18:45 EDT 2004 | msjohnston1

Ricardo makes some good points. My idea of a dream line is one that flexible to run as a high mix/low vol and low mix/high vol. I personally like Dek printers over MPM. The new printers from Mulara look interesting but they are a new company with a
