 Do you know the rigid pcb?

   The important varieties is generally the rigid pcb material.The rigid pcb is reinforced materials (Reinforeing material), in dipped with resin adhesive, through drying, cutting and stacking synthetic billet and copper clad laminates, steel plate as a mold, in the hot press under high temperature and high pressure forming.

Prepreg for multilayer board, CCL is in the production process of semi-finished products (mostly glass cloth impregnated with resin, drying and processily.The rigid pcb is reinforced materials (Reinforeing material), in dipped with resin adhesive, through drying, cutting and stacking synthetic billet and copper clad laminates, in the hot press under high temperature and high pressure forming and made. Prepreg for multilayer board, CCL is in the production process of semi-finished products (mostly glass cloth impregnated with resin, drying and processing).

Substrate is the basic material of rigid pcb manufacturing, under normal circumstances, substrate is copper clad laminates, single, double-sided printed board in manufacturing is in the substrate materials - copper clad laminates (Copper-2lad I. Aminates, CCI).

   On selected hole machining, chemical plating, copper plating, etching processing, to obtain the desired circuit pattern. Another type of multilayer printed circuit board manufacturing, is within the core thin copper clad laminate substrate, conductive pattern layer and semi solidified sheet (Pregpr 'of the EG) alternately by one-time laminating adhesive together, forming three or more layers of conductive pattern layer interconnection. It has three aspects, conductive insulation and support function. PCB performance, quality, manufacturing process, manufacturing cost and manufacturing level, depends largely on the substrate material.

   Substrate material and production,it has gone through half a century of development, annual output of around the world has reached 2.9 million square meters,the development time is electronic machine products, semiconductor manufacturing technology,electronic installation technology, printed circuit board technology innovation development drive.In 1959, the United States Texas Instrument Co produced the first integrated circuit, printed circuit board to put forward higher requirements for high density assembly, thereby promoting the production of the plywood.
