Solder resistance coating is a kind of protective material suitable for the exterior surface of circuit board. The solder resistance coating will cover the entire surface of the board, including metal and dielectric materials, except for the pads and hole
pcb board quick proofing is generally charged according to the information provided by customers and process requirements. For example: the number of boards, process requirements, ink color, board thickness, difficulty, expediting time and so on, a compre
PCB geographical proofing refers to the trial production of printed circuit boards before mass production of boards. After the engineer finishes the design, the PCB file is sent to the circuit board manufacturer for processing into PCB boards. For some pr
Solder pad refers to the part of the board to be coated with green oil. In fact, the solder mask uses a negative output, so when the shape of the solder mask is mapped to the board, it is not green oil solder, but exposed copper. Usually in order to incre
It is the national comprehensive reform pilot zone, the national logistics hub, the Southeast international shipping center, the pilot free Trade Zone, and the national Marine economy development demonstration zone. It has become the cross-Straits emergin
But as digital circuits became faster and RF circuits were incorporated into PCB, boards became the limiting factor in many designs, and while CAD tools can help engineers design boards, CAD's automatic wire-winding capabilities often cause more problems.
With the PCB design time is shorter and shorter, the size requirements are smaller and smaller, and the device density is higher and higher, the PCB design is more and more difficult. Many manufacturers tend to use special EDA tools to achieve PCB design.
With the decrease of signal rising time and the increase of signal frequency, we pay more and more attention to EMI problems of electronic products. Almost 60% EMI problems can be controlled and solved by high-speed PCB.
Designing high-speed systems requires not only high-speed components, but also genius and careful design.
the process of resin plug hole has been used more and more widely in the PCB industry, especially in some high layer, the board thickness of the product is favored. It was hoped that the use of resin plug holes would solve a range of problems that could n
The appearance of poor tin pcb is generally related to the cleanliness of PCB empty board surface. If there is no pollution, there will be no poor tin. Second, the solder itself is poor, temperature and so on.
