Mike: You're correct, but in better shops there are guys with little black books in their back pocket. They know how to contol their variables and give you a good product. I worked at this plant where we cooked dirt. It glowed orange-red and flow

Any good stencil house should be able to recommend the proper configuration on a fine pitch aperture design. They can also advise you as to which foil thickness works best. The norm foil thickness is .005" - .006". There are always special instances

Not all but some new boards we have had solder joint problems, for example some of the pads refuse to solder at all and the solder paste ends up attched only to the leg, reworking makes no difference and a variety of fluxes have failed. How can some

At the s#$t-hole Contract Manufacturer where I work (name with-held), the motherf&ckers told us to wash them useless pieces of sh&% once a week, and "don't use fabric softener" otherwise you ruin the integrity of the faraday cage. Then they got on th

If the equipment was originally 'quad'....then....they had already had some spec'd out for each machine. I would try calling them and seeing if they still have the 'old' documentation. If that doesn't work....you could try any reputable company that

No not really. They are inspected with gloves, but all PCB's are in our facility, no matter what the finish. They are stored in the same packaging material that they are shipped in. We haven't been using ImmAg for that long yet, so maybe we will se

Hi all, I want to know the possible causes of poor paste release in stencil printing process if the same brand and part number of solder paste that has been used successfully is being used with a set of process parameters which worked before. Other t

This was the test method mentioned to me about 5 years ago, to use for testing for black pad, when we were evaluating the use of gold immersion for the first time. It is not practical for testing the entire surface of a PCB, but it should work well

It really does not say what it is. We used to use oil on our wave, it even had a built in pump and drain in the pot to keep it fresh and at the right level, worked great, made a hell of a mess. A big no-no for no-clean. I think most people got away f
