We use a number of conformal coating materials. When you say you think you want to use a UV material do you mean UV cure, or just material with a UV trace for inspection purposes? For selecting appropriate materials take a look at IPC-HDBK-830. Keep

You should have a number of lighting options to deal with the low contrast lettering. Low angle, B/W, reverse color. etc... If I am reading you right, you might have your bridge inspector too far out on the lead banks, that it is seeing the silkscree

I'm looking for a preheater for hand soldering, but haven't used one before so I could use some advice. Does anyone have any preferred styles or brands? Is there anything in particular that I should either look for or should avoid? I've seen prices r

I am wondering if anyone has had issues with their Heller oven rails warping. It appears that our 1800EXL and 1900W oven rails sag after time. They eventually contact the safety mesh and then create hestitation of the chain, thus creating defects.

Sorry to hear of the difficulty with the rails on these systems. The 2 machines mentioned are 10 years old or more. The rails typcially last quite a while but replacement after 10 years is possible. Please feel free to e-mail me directly to discus

We have 1880 Heller about 12 years old and running like a charm everyday. I doubt that lead or non-lead operations will have anything to do with it. Do you use high temperature lubricant on edge hold chain and rail periodically? This may help to ease

A question for all you wave experts out there: We run our wave with a constant flow over the back plate. I know it's recommended that we set the back plate so that the solder sits just at the top of the back plate with surface tension keeping it fr

Pete, It would even be better if the wave machine manufacturers would add a feature that allows the wave to drop in rpm when a board passed the wave, and slowly get the wave back to normal rpm when a new board approaches. This would be like a reset

Has anyone used their AOI to try to catch components that may be inadvertently placed in a location it shouldn't be? Every once in a while our equipment may drop a part onto a PCB and that part will adhere to pad. So the question has been brought u
