Terminal requirements for printed circuit boards
Printed circuit board (referred to as "PCB", or printed Wire Board, referred to as "PWB"), printed circuit board is a key interconnect for assembling electronic parts, which not only provides electrical connection for electronic components, also carries the digital and analog signal transmission of electronic equipment, the power supply and the RF microwave signal launches and receives and so on business function, most electronic equipment and the product need to equip, therefore is called "the Mother of Electronic Product ".The manufacturing quality of PCB not only directly affects the reliability of electronic products, but also affects the integrity of signal transmission between chip and chip.The development level of its industry can reflect the development speed and technical level of the electronic information industry in a country or region.
Terminal requirements for printed circuit boards
The terminal requirements of printed circuit boards can be divided into enterprise-class user needs and individual consumer needs. Among them, enterprise-class user needs mainly focus on communications equipment, industrial medicine and aerospace and other fields. PCB products often have high reliability, long service life, trace ability and strong characteristics.The corresponding PCB enterprise qualification certification is more stringent, certification cycle is longer.
Individual consumer demand is mainly concentrated in the computer, mobile terminals and consumer electronics and other fields, PCB products usually have a thin, small, flexible and other characteristics, the terminal demand is large, the corresponding PCB enterprises have high-volume supply capacity.
Sample is the front link of PCB mass production. In general, only the successful development and market testing, stereotypes, to determine the actual production applications will enter the stage of mass production. And according to the size of the batch, the general can be divided into PCB batch requirements for small-batch board (20m² below), Medium-batch board (20m²-50m²) and a large number of boards(50m²above).
