LPKF Laser & Electronics has introduced the MiniContac RS, a desktop electroplating system. The system is ideal for rapid prototyping of printed-circuit boards (PCBs) in tight spaces. The system employs reverse-pulse-plating (RPP) technology for uniform metal distribution. It can plate holes as small as 8-mil (0.2-mm) viaholes in 62-mil-thick standard PCBs. The system handles circuit boards as large as 9 x 13 inches (230 x 330 mm) and is completely closed with no external connection needed. It can also perform plating on through-holes in double-sided and multilayer boards. The system uses only four tanks, which can easily be replaced. LPKF can handle complete disposal of all plating chemicals.
