Hi Russ, I thought about it and what approach I would do. All that talk about causes and reasons doesn�t solve the problem. To determine wether it�s the PCB, the component or the process I would take a bare board, a component ( and maybe a different

We are using the omega meters to determine the solvent extract conductivity. The book is refering to standard MIL-P-28809 who specifies a 14 ug/sq. in. of Na/Cl limit. The past owner of our machine was setting the pass/fail limit at 3.6 ug / sq. in.

Having formerly worked for a solid rocket motor manufacturer, we were extremely concerned with ESD. I'm not sure of the specifics, but all our floors were painted (concrete). All employees in these areas wore steel toed, conductive shoes, to dissip

Some NC fluxes work well with conformal coatings others do not. Your coating materials supplier should be able to help. If they can't you're talking to the incorrect person. Try our friend Graham.Naisbitt@concoat.co.uk www.concoat.co.uk CONCOAT Lt

I work for an R&D company that is starting to do some prototype and limited production circuit cards. We are deciding how we want to build these boards, and we are wondering what we should do about flux and cleaning. We have circuits that run at 15

Hi Jax, The alignment pop up only on some parts and it's random axes. This happens every prototype run that I need to adjust the alignment of some parts. Fiducials are correct and okay. Also had done calibration on our machines. I really suspect that

I have one suggestion why don't you align all parts and take a close look at it if you can find any misaligned component after that. IF SO, that's machine's repeatibility problem.(or mechenical problem-dirty nozzle, wrong pick up and placement height

We have this same model and are very disappointed with it. It has several issues that we do not like: 1. The solder feeder has never worked properly. 2. The fingers are very soft material and bend easily. 3. There is no way within the machine to adj
