PCBA OEM refers to a variety of raw materials used for PCBA OEM, and it can customize PCB board to meet the diversified product needs of customers, the use of advanced automation technology, improve production efficiency, and the product has good reliabil
How to choose PCBA processing manufacturers: first, whether there is a standard procedure flow; Second, whether the standard is implemented; Third, the time of delivery
The global PCB industry is mainly distributed in China, Taiwan, Japan, South Korea, Europe and the United States. With the transfer of global PCB production capacity to China in recent years, China has become the world's largest PCB industry output region
PCBA three anti paint coating methods: 1, impregnation, 2, spraying, 3, brush coating, 4, selective coating
Large scale, top ranking PCB enterprises mainly produce large batch board, PCB enterprises positioned in small batch board are relatively few, in addition to the company, the domestic production of small batch board representative enterprises mainly Chong
During heat treatment, the material's mechanical strength, dimensional stability, adhesion, water absorption, thermal cracking, expansion performance and other aspects are different, high density products are obviously better than ordinary PCB substrate.
the printed circuit board has entered the stage of surface installation and chip installation, and the process requirements are increasing, so the warping requirements of the circuit board are becoming higher and higher. Therefore, we have to find out the
The pressing process of printed circuit board is the main process of generating thermal stress. Similar to the pressing process of copper clad plate, it will also produce local stress caused by inconsistency in the curing process. The printed circuit boar
The following is a calculation example of the position accuracy of the intermediate component of PCB board in the following two positions (the position accuracy calculation of the length direction is only taken as an example, and the width direction is no
With moisture-proof, anti-corrosion, shock-proof, protection function. Now, you know why to apply three anti-rubber on the circuit board, have the need of small partners do not quickly act.
For the fabrication of circuit boards, the more layers, the more complex the process, the higher the failure rate of course, the higher the cost, so the multilayer board can only be used for advanced circuits.
the color of the circuit board has attracted the attention of the industry, mainly because the color design of many high-end circuit boards are made of green, so people slowly believe that the color of the circuit board is green must be high-end.
