Thin dry‑film solder mask systems deserve consideration in UHDI applications. Modern dry films can reliably image clearances on the order of 60µm and, in some cases, offer better dimensional stability ...

Copper corrodes quickly when exposed to oxygen. You must protect copper traces on outer layers from corrosion by passivation or by coating them with an inert material. Passivation refers to any ...

Flexible printed circuit (FPC) coverlays are meant to overlay and protect the fine circuits, giving them flexibility and sheltering them from damage by temperatures, humidity, pollutants and erosive ...

The cheapest PCBs – and therefore most common – are green solder mask with white silkscreen. It works, but it’s also incredibly boring. This is the way things were done up until a few years ago with ...
