Multilayer PCB refers to a printed circuit board with more than three conductive pattern layers and insulating materials between them, and the conductive patterns are interconnected according to the requirements. Multilayer circuit board is the product of the development of electronic information technology to high speed, multi-function, large capacity, small size, thin and lightweight.
Printed circuit boards are usually bonded with a layer of copper foil on glass epoxy substrate. The thickness of copper foil is usually 18 μ m, 35 μ m, 55 μ m and 70 μ M. The most commonly used copper foil thickness is 35 μ M. When the weight of copper is more than 70UM, it is called heavy copper PCB
The names of circuit board are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, heavy copper board, impedance board, PCB, ultra-thin circuit board,printed circuit board, etc.
Coil PCB, we know, electricity generated magnetic, magnetic generated electricity, the two complement each other, always accompanied. When a constant current flows through a wire, a constant magnetic field is always excited around the wire.
100G optoelectronic PCB is a packaging substrate for a new generation of high computing, which integrates light with electricity, transmits signals with light and operates with electricity. It adds a layer of light guide to the traditional printed circuit board, which is very mature at present.
Rf-35TC PCB is Taconic high thermal conductivity low loss laminate, high Tc, DK 3.5 substrate, DF 0.0011, is a good choice for high frequency, radio frequency, Microwave PCB
