FDA = Food and Drug Administration. Typically, the FDA requires a validation of every product that will ultimately go to consumers. The validation process is the basic "run it the same way with the same results" over a period of time. Back in my Phar

Our solder paste machine has a squeegee problem. After passing over a board, the squeegees don't go all the way back up to their origin state. Then we are getting a timeout error and have to return the machine back to its origin (manually), and pass

If you would be so kind as to share what you ended up going with and why I would really appreciate it. I have to implement a rework station at my company but I don't have as much time and resources as I would like to evaluate all the available syste

We should be getting close to a new "deadline" huh? what is going to happen in Europe when the day comes and "it just aint ready" Will they actuall stop importing and using? I have not read the directive for all of the little nuts and bolts so thi

We are going to start conformal coating PCB assemblies, and I was wondering about cleaning the boards before coating them. Do I need to clean them and if so, with what? We currently us a no clean solder. I am worried about contamination on the board

some coatings are more forgiving to surface contaminations than others. best way to go about is select some coatings with the properties you need and then trial the boards to see any coating defects (like dewetting, pinholes, flaking etc) wiping wit

0603 parts at .2mm spacing is pretty easy. But are there any other parts, like fine pitch QFPs? Is your board HASL or something else? Is there resist/mask between all pads? If it's just 0603's at .2mm, then you can probably go 7 mils and get good

We are fixing to run a board with both pb and pb-free BGA's..double sided.. The board is RoHs compliant so I could go either way on the solder paste. I was thinking pb-free paste would be the best bet. Any opinions would be greatly appreciated. Th

Warp depends on: * How close the board gets to its Tg during the reflow cycle (the closer you get to the Tg the worse the warp gets) * Amount of copper on each side and the balance between the two * Thickness of the board * Overall length x width * T

I've never had this problem on an Omniflo oven, but have seen it on others. It has always turned out to be mechanical. A bearing going bad or FOD in the rails. I would pull the chains and carefully check each link of both chains, all of the bearin
