Your thinking is correct. Wave soldering pads that were designed for reflow can create problems: * Large pads used for reflow [too much solder] can create reliability problems. * Bridging [too much solder] creates rework. * Skipping & shadowing from

IIT is a reputable supplier. They will be more than happy, happy to help a newbie get a good product. Continuing, at one level of product design sophistication ordering by remote will provide you with a perfectly acceptable stencil. But on the o

Hi Wow Genny, I don't think I could have given so much detail so fast. I have designed some high RF test designs for testing purposes to pass only the High Frequency, yet I didn't want to muddy the water with this other side. Now you did it well a

There have been many designs of apertures for 0402, round, home plate, inverted home plate and various reduction amounts for square or rectangular apertures. What works best for a given application depends on PCB design, solder land finish, stencil t
