1. Printed circuit board (PCB) is the abbreviation of printed
circuit
board. Usually, the conctive pattern made of printed circuit, printed component or combination of them on insulating material according to predetermined design is called printed circuit. The conctive pattern that provides electrical connection between components on insulating substrate is called printed circuit. In this way, the printed circuit or the finished board of printed circuit is called printed circuit board, also called printed circuit board or printed circuit board. Circuit boards can be divided into the following categories according to their functions:
, single-sided circuit board, double-sided circuit board,
, multilayer circuit board,
, aluminum based circuit board,
, impedance circuit board,
, FPC flexible circuit board, etc.
the raw materials of circuit boards are glass fiber, CEM-1, cem3, FR4, etc The core of fireproof felt is glass fiber, which is easy to combine with resin. We immerse the glass fiber cloth with compact structure and high strength into resin, and harden it to get a heat insulation and inflexible PCB board. If the PCB board is broken, the edge is white and layered, which is enough to prove that the material is resin glass fiber
the board with a lot of small parts inside the appliance is called circuit board (also called PCB)
circuit board has a history of more than 60 years since its invention. History shows that without circuit board and electronic circuit, flight, transportation, atomic energy, computer, aerospace, communication and home appliances can not be realized. The truth is easy to understand. Chip, IC, integrated circuit are the grain of electronic information instry. Semiconctor technology reflects a country's instrial modernization level and guides the development of electronic information instry. The electrical interconnection and assembly of semiconctor (IC,
IC) must rely on circuit board. As Kobayashi, the author of Japanese printed circuit board collection, said: & quot; If there is no computer and data, electronic equipment is equal to an ordinary box; Without semiconctors and circuit boards, electronic components would be ordinary stones& quot;
PCB is a promising instry in China, with a double-digit growth rate every year. Many foreign orders are put into China, so there are opportunities
for example, the motherboard in a computer is a circuit board
