PCB circuit board has several materials?

PCB circuit board material can be divided into two categories: rigid substrate materials and flexible substrate materials.

steel plate as a mold, in the hot press by high temperature and high pressure forming process Into the. General multi-layer board with the semi-cured film, it is CCL in the production process of semi-finished products (mostly glass cloth impregnated

It is reinforced with a material (Reinforeing Material), impregnated with resin adhesive, through drying, cutting, laminated into a blank, and then covered with copper foil,

Its development has been 100 years of history; its design is mainly layout design; the main advantage of using the circuit board is to greatly reduce the wiring and assembly errors, improve the level of automation and production labor rate. According to the number of circuit board can be divided into single-sided, double-sided, four-tier, six-board and other multi-layer circuit boards.

PCB circuit boards, that is printed circuit boards, also known as printed circuit boards, electronic components is the electrical connection provider.
