Product description

multilayers PCB21.jpg

   PCB multilayer board refers to a multilayer circuit board used in electrical products, and multilayer boards use more single-sided or double-sided wiring boards. Uses a double-sided inner layer, two single-sided outer layers or two double-sided inner layers, and two single-sided printed wiring boards, alternating with a positioning system and insulating bonding material and conductive patterns The printed circuit boards that are interconnected according to design requirements become four-layer and six-layer printed circuit boards, also called multilayer printed circuit boards.

   With the continuous development of SMT (Surface Mount Technology) and the continuous launch of next-generation SMDs (Surface Mount Devices), such as QFP, QFN, CSP, and BGA (particularly MBGA), electronic products have become more       

intelligent and miniaturized. Promoted major reforms and advancements in PCB industry technology. With the rapid development of high-density interconnect (HDI) micro-plate processing technology, PCB design has gradually developed to multi-layer, high-density wiring.


Multi-layer PCB has many advantages, such as: high assembly density, small size; short connection between electronic components, signal transmission speed, convenient wiring; good shielding effect, and so on. The number of layers of the multilayer board is not limited. Currently, there are more than 100 layers of PCBs, and four-layer and six-layer boards are common.
