Heavy copper PCB boards ( also being called thick copper board, power board etc ) are usually bonded with a layer of copper foil on a glass epoxy substrate. The thickness of copper foil is usually 18μm, 35μm, 55μm and 70μm. The most commonly used copper foil thickness is 35μm. The thickness of copper foil used in China is generally 35-50μm, and there are als...
Aluminium PCB board, also named Aluminium based PCB, metal clad (MCPCB) PCB, insulated metal substrate(IMS or IMPCB) PCB, thermally conductive PCBs, etc. Aluminum printed circuit board ( PCB ) is a unique metal-based copper clad laminate with good thermal conductivity, electrical insulation performance and mechanical processing performance. It is composed of...
Multilayer circuit boards refer to circuit boards with three or more layers, two of which are on the outer surface, and the remaining layers are combined in the insulating board. The electrical connection between them is usually achieved through holes on the cross section of the circuit board. Multilayer printed circuit boards are most complicated than other...
HDI is the abbreviation of High Density Interconnection, which is a kind of technology for the production of printed circuit boards. High density interconnection PCB board is a circuit board with a relatively high line distribution density using micro-blind and buried via technology. HDI includes the use of fine features or signal traces and spaces of 0.003”...
