PCB proofing refers to the trial production of printed circuit boards before mass production. lt is mainly used for the process of conducting small batch trial production to the factory for electronic engineers after designing the circuit and completing the PCB, which is called "PCB proofing".
Current status of PCB development The main function of PCB is to make various electronic components form a predetermined circuit connection, and play a role of relay transmission.It is the key electronic interconnection of electronic products, and the support of electronic components and the carrier of electrical connection.
Data shows that China's consumer electronics and major industry sectors are rapidly expanding their demand for PCBs.The circuit board manufacturing industry will develop along the path of high-density interconnect technology (HDl) and continue to sell. This is worthy ofattention. event.
The raw materials used in PCB proofing include "ink" and "plate". Different brands/grades of raw materials are selected, and the price also changes. High-quality raw materials are not only baked at high temperature, but also have strong flame retardancy, bright colors and bright colors. Long service life.
Common surface treatment requirements for PCB proofing include: thick plate, number of layers, copper thickness, minimum aperture/line width/line moment, surface treatment, etc. The higher the parameter, the more expensive the price. Secondly, the surface treatment of immersion gold is more expensive than spray tin. The smaller the process capability parameter, the more expensive the price.
As we all know, the more the number of PCB proofing production, the more affordable the price. Our company mainly produces mass production. The cost of PCB proofing in the early stage can be returned to the cost of proofing and test racks according to the situation during mass production. Customers with large quantities can enjoy free PCB proofing service in the later stage. .
The conventional PCB single and double-sided board proofing cycle is 4-5 days, and the PCB multi-layer board proofing cycle is 6-8 days. It can be expedited according to customer requirements. The shorter the delivery time, the more expensive the price. Old customers have twice a month Free rush order permission.
To provide domestic and foreign enterprises with a full range of one-stop services from circuit board design to manufacturing.
