Hi CW, Larger chip caps can be susceptable to cracking, but mainly this is due to handling - flexing of boards is the main culprit (the part being mechanically joined at both ends to the board). PCB's usually flex easiest along one axis, and larger

LOZ. Under-cured or out-of-spec(sloppily) applied resist is realistic. What other physics: Shiny resist surface is more prone to balls then matte finish. How about an operator eating fish & chips before handling the boards. Don't laugh... ... saw th

IPC7912 deals with the end result, ie an OEM getting boards from a contract manufacturer. I have a friend who is sitting on these committees. He tells me there is a new standard due out for actually doing in-process DPMO. From a process standpoint

Dear Hegemon, I'm very grateful for your help. There is one more thing that I'd like to discuss with you. I'd like to know if there is any "verification board" or something like that to check if you really did a good job. At the company where I wo

dear all, update: we got that the calibration of SIM is the problem, the distance between SIMs need to be calibrated. can someone help us get the manual that describe on how to calibrate the SIMs? we have a problem with our cyberoptics AOI machine

hi Bob, Thanks for the info. I understand your comments, but I am looking for specific guidance, If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? (I realize this is dependent on h

Hi Samson ! In order to give you more detailed information I would like to know what your component range is and how many boards you supposed to do. Panasonic and MPM are a good choice, however, Panasonic has not many P&P machines on the U.S. market,

You are on the right track Ismir. Essentially however, as the programmer of the machine, I am the one that creates the PCB with the errors to benchmark the settings for the machine. No secret lab though! :-) Easy enough for most any AOI machine to

Have you tried to restart F4G and/or MCS/30 after flushing the CP4 memory? I have occasionally ran into the comm error after a reset start. Leave the machine on and restart F4G or the MCS/30 whichever normally is hooked up. If it still won't commu

Hello everyone, Last year, our company ventured into the SMT arena to manufacture PCBs in-house for our products. We've been utilizing two Neoden 10 pick-and-place machines in series. However, as we grow, we've encountered some limitations with our
