I want to know how you measure capacitance and resistance to 01005 components?Is there such a machine for automatic measurement of component values on PCB? We have a lot 01005 components and we lose time to measure first panel components...I'm inter

We measure each first board before the oven after every chageover...Assembling one offset and measure component, after we clear plate...We have reason why do that...But we're wasting a lot of time.So I wanted to see how you do it. Thank you for answe

Dear all, I have an issue here where we found BGA crack. Understand from friend, we need to study any possiblity of our own jig or fixture cause this problem via strain gauge measurement..My question: Is there any standard @ specification establish

First, you cannot measure capacitors once they are soldered onto the board. Second, why must you measure? Verify your machine set up by using intelligent feeders (if your machine has them) or a checklist, preferably by two people. If you cannot trus

If I remember correctly the standard we used was something like 350 candlepower at the work surface, and it can be measured with a standard photographic lightmeter

There's always flying probe, although it's not particularly cheap.

There is no standard for a strain gage measurement of allowable deflection of a board or a fixture. It's possible that your fixture is causing the BGA cracking that you see. What protion of the BGA is cracking? If it is the solder connection, sear

This might be a good place to start...I'll let you read it and tell us how helpful it was. ;) http://www.nesllc.com/acrobat/LightingFund.pdf
