Latest Patents

Lacher holds a patent for a method that allows for the production of two-sided printed circuit boards with very small rings surrounding the plated through holes. This process begins with a through-plated copper laminate, which is then coated with a liquid negative electrodeposition photo-resist. The coated photo-resist is exposed to light through a carefully designed mask that prevents light from reaching the through-platings. After the non-crosslinked photo-resist is removed, a metal or metal alloy resist is applied through electrodeposition on the exposed surfaces. Finally, the crosslinked photoresist material is removed, and the uncovered copper laminate is treated with a copper-etching solution to eliminate the exposed copper surface.
