Multilayer printed circuit board

1 layer2-layers

The Carbon Ink PCB is made of carbon paste screen hole filling process. Carbon particles are evenly distributed in thermoplastic resin to make conductive ink, and then covered with soldermask. Its toughness is high, its thickness is thin, its insulation is good, and its price is lower than that of gold plating. It is often used in high voltage, pulse and high frequency circuits. The most common methods of making circuits on printed circuit boards are subtractive method and additive process method. Additive process uses electroless copper or electroplated copper to generate circuits, and making conductive Carbon Ink PCB is also a kind of additive process. Conductive carbon ink is used to make wires, which are printed on insulators. With this method, it is easy and effective to make conductive Carbon Ink PCB with various shapes for printing. The production process of Carbon Ink PCB is a combination of subtractive method and additive process's PCB board manufacturing method. At present, conductive Carbon Ink PCB have made breakthrough progress in application fields, especially in electronic products with low electric power. As a permanent conductive coating on conductive Carbon Ink PCB, conductive Carbon Ink PCB have been adopted and popularized by many electronic designers. Conductive Carbon ink, with mature and stable production technology, leading product quality, excellent printability, heat resistance and moisture resistance, and stable heating performance, is widely used in far infrared drying oven, incubator, electric blanket, sauna room, floor heating board for electric heating, and electric heating in greenhouse. It has broad development prospects.
