| We're getting field failures in a high impedance portion of the circuit. Think the unpopulated pc card has contaminates because we were able to grow dendrites by applying a 9 volt battery across the suspected pad, placed a drop of de-ionized water

Surface Mount Components like QFP's in Tray usually comes sealed in an anti-static plastic pack. In case the QFP's were removed from the said anti-static bag for more than 2 weeks, do these components needed to be baked for they might produce solder

So is anyone going to attend Nepcon Texas in Dallas, or is it a waste of time? So far I don't see some of the big players, and I would assume they would have their trade show dollars mapped way in advance. Being in San Antonio (should I say that

Very shortly I will be evaluating OA flux and aqueous cleaning to replace our RMA and solvent cleaning process. I am primarily interested in batch aqueous cleaners for reasons of budget, floor space, etc. I am concerned about the ability of H2O to

Currently, we are baking any PCB before process on SMT, the 'reason' is to dry any possible humidity that could be inner the PCB, it does not matter if the PCB is multilayer or not. We bake PCB's at 107C for 4 hrs and the board must be process into n

I would recommend Zestron's Vigon SC200. It does not require a rinse as long as you cleaner is equipped with a wash solution filter to filter out the solids. Zestron # is (888) 999-9116. The toll-free # is frequently busy� If so, try (703) 589-11
