After more than a decade of research and development, Tokyo Electron Miyagi Ltd. has introduced an innovative semiconductor ...

There may be nothing new under the sun when it comes to etching PCBs with UV light, but [Heliosoph] has brought finer control to a used face tanner he bought that now exposes his boards in ~50 seconds ...

CNC machining mills away copper using a CNC router and design software chemical etching uses UV light, photo-resist, and chemicals to remove copper CNC machining is safer and less wasteful, but slower ...

The method of printing PCBs has not changed for decades. In the early days of imaging circuit boards a substrate (copper laminate) was screen printed with a liquid etch resist; this was then oven ...

While low-cost professional PCB fabrication has largely supplanted making circuit boards at home, there’s still something to be said for being able to go from design to prototype in an afternoon.
