We have found differing results based on the pattern used when reducing to total % of solder paste on the center pad. We arrived at 68% coverage on the center pad, and 1:1 for the perimeter pads. To get the 68% coverage we used a number of differen

Q: The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? A: Yes, but somebody here don't agree with me that the glued part need help from wave to get the good wetting. They are wrong

I am not completely sure why it would tell you "board will not be populated" and then build it anyway, but if the only difference between the two programs (working one, not working one) is the fiducials are smaller, did you try reducing the search ar

Maybe a silly question, but........... Sometimes we get PCB's in with defective(distorted) fiducials that the production equipment(printer, PnP, etc) does not recognize. It would be great if there was a product out there to replace the defective f

I don't know how accurately you're going to be able to put a replacement down. You could use BGA replacement pads, but that is a lot of time and the results will be shakey. On the DEK, make a copy of your program and teach some pads or through hole

Here are some questions you should be considering... How many of each machine type are actually installed and being used in the market? What is the local support in your area from each vendor? Where are their spare parts warehoused? What is the w

I have a JVC home stereo and it just started shutting off roughly a couple of seconds after turning it on. I took off the cover and found a capacitor that the plastic coating on the outside peeled off. Could this capacitor be my problem, the reason w

I haven't specifically heard of any laminate material that is ESD safe...but I haven't really researched it a whole lot. However, our "ESD" guy found a spray on substance that protects from ESD. We use it for all the plastic garbage cans at our faci

Whoa dude - slow down- maybe great beer money but if you don't have good environmental and ESD controls in your shed, all your suds slush fund will evaporate in RMA's costs. A small pick and place (table top) would do. A manual screen printer would h
