Hi, I have a test pcb that came with my Yamaha YM84S machine. The board contains land patterns, fiducials, etc. The pyrpose of the board is to test the placement and vision systems in the machine. Does anyone provide the technical drawing of the bo

Anybody out there know of a good (2nd) source to purchase single magnetic board supports used on quad/samsung machines. These are spring loaded and contact the underside of the board in the pick n place machine

Is there a standard to specify how many times a profile board can be used? if No, then could I say that it depends on the actual board appearance (discoloration,delamination etc.) then it's time to replace a new one. Thanks in advance for sharing.

We have a small board about 1" by .5" and it is .012" thick. It is in a 50 up panel. We have tried rat bites and v-score and we keep seeing delamination around the edges. Anyone have experience depaneling boards this thin?

100% visual inspection. If we test, then we retest (assuming this is a completed board). Also, if there is an accelerometer on board, we argue about whether or not we should replace it by default.

It depends on your product application requirement, normally should not drop off board for automotive. Even the dropped board pass function test in plant, it will have problem in its working environment.

Basically the same exact way as a much smaller board. The only difference is the profile. Most of our boards are 0.063" thick. Looks like you found your problem. If the edges of the board are cold relative to the rework site (high difference in t

It sounds like you may be thinking of two different test methodologies. What is required? Bare-bard testing, to verify pcb fabrication? Or populated board testing, to verify manufacturing? If it's bare board testing, the fab house should advise a

Yes, you can ask for scrap boards, buy Dummy boards/parts or engineer off past runs. For this cost, I would profile, profile, profile. I would make/buy a dummy board. If you don't have one this thick, glue/ adhesive/ bolt some scrap boards togeth
