Homebrew PCBs

Greetings. I have recently developed and released, Solder Resistant Mandrel Technology, Copper Foil Vias. Use to produce through hole, blind and buried vias at your workbench or kitchen table. It is a quick, easy, inexpensive, space saving, non-hazardous method to produce quality electrical and mechanical connections between top, interior and bottom conductive layers of multi-layer PCBs. Suitable for Hobby, R& D, Prototype and Limited Production Runs.
