The role of PCB
In order to avoid the errors of artificial connection to achieve automatic insertion, welding and testing; ensure the quality and reliability of electronic machine products; improve labor productivity, reduce production costs; convenient maintenance and other conditions in the China pcb assembly. Therefore, the printed circuit board (PCB) is used in the electronic machine equipment. Specifically there are the following three major roles: First, offer the function of parts welding solder graphics; PCB provides solder graphics for the components welding and identification character checks and cartridge for parts repairmen; Second, the wire links to the parts; PCB can achieve the connection between the various parts and electric or electrical insulation, and can provide the required electrical characteristics, such as a high-frequency microwave signal transmission and the characteristic impedance; Third, the function of supporting the parts; offer the assembly of the various components (such as resistors, integrated circuits, capacitors, etc.), and the fixed mechanical support.
The application of PCB
PCB (printed circuit board) has a very wide range of the use, and can be used in almost all electronic equipments, both can be used in the computer mouse and the mobile phone and be used in the car and on the rocket. But it is mainly used in the following ranges: First, computer and peripheral products: monitor, host, server, such as a mouse; Second, Communications products: cell phone, home landline, satellite, etc. Third, consumer electronics products: refrigerator, microwave, air conditioning, etc. Fourth, Industrial Products: punching machines, motors, etc. Fifth, others: military weapons, rockets, etc. China's sustained and rapid development of electronic communications production is an important guarantee of the rapid development of printed circuit continued production. pcb manufacturer China has sustained the annual growth of more than 20% of the speed in the last decade. Not only production output value will become the world's second largest after Japan and the product quality is also rising, developing from the middle and low to high-grade level. High multilayer the HDI board and flexible circuit boards are in rapid development.
The development of PCB industry in China
In order to strive to improve in the international competition, one of the most important things for Chinese enterprises to carry out is to introduce the situation and development of the world's electronic circuit more timely, in particular, to be more systematic introduction of the latest technology, materials, equipment and trends of modern printed circuit, including raw and auxiliary materials and special equipment such as copper clad board, so that enterprises can quickly understand and keep up with the world trend. www.pcb-pcba.cn has more than 10 years experiences in the PCBs industry; our products include sigle-dide, double –side board, multilayer boards (1-20layers), High-density multilayer PCBs and Aluminum based PCB.
