| We've noticed that there are many different recommendations for pad sizes for various SMT parts. This seems to vary wildly from manufacturer to manufacturer for the same case sizes. Is there any standards that can used used to specify these sizes

With poorly cured mask: * Wave soldering: Expect to see thin wavy band of dross imbedded in the mask in the wave solder side. * Reflow soldering: Expect to see a pinto board where the two tones of mask are [1] normal color and [2] a lighter color, al

Hi, undercured solder resists may be a defect people have seen so far. Some of the probles arising is blistering as well as reaction with wave solder flux that may lead to some kind bad gel like formations. Gels the idea would be to reflow the ba

I have been advised recently about pcb manufacturers, that somehow or other supply pcb's with contamination. Visually they are fine, but problems arise during SMT manufacture, ie solder balling, non-wetting on pads, and also during wave solder proces
