I'm not sure why anyone would pay extra for FG (fine grain) stencils. I've run studies comparing traditional YAG laser, fiber laser, and E-form stencils with regular stainless, FG, and nickel foils. YAG is the worse and should only be used for pret

Neither the Omega meter nor the IC are officially "destructive" tests, but everywhere I worked we treated them that way. The boards were scrapped after the test. The Omega meter can be tested at elevated temps, but the IC sample is extracted at ele

The more that I chew the idea of outgassing through the pad theory, the less I like it. Why would something, water???, choose to outgass through the pad when moving through the solder mask would be a path of much less resistance? And why wouldn't the

I've got a scary one for you guys and desperately need your help - We just purchased a second Quad 4C and had some communication problems when we first turned it on (we're still working on that issue). To chase down the problem, we decided to start

High Relative Humidity and Blistering Issues in Assembly

Off hand, I can't recall a "formula" for how long boards could sit in a specific RH environment. I've done a couple of quick Google searches, and can find a bunch of information on the dispersion rate of moisture in various PCB materials, but, nothi

I have an issue with this DEK printer our company has been having for over a year now. It seems that DEK can’t narrow down what the issue actually is as well. The printer is a DEK Horizon 03i 09 SP13 P02. We are having an issue with the camera.
