What function does pcb board resin plug hole have
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
Causes and improvement measures of defective tin on pcb board
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.
pcb board fast proofing industry proofing need how much cost
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
Ten PCB circuit board design questions and answers
PCB technology is very complex, involving many aspects of the problem, whether in the design stage or the production stage, there are a lot of problems need to be answered.
What problems should be paid attention to in high speed PCB hole design?
he PCB hole is mainly composed of the hole, the bright plate area around the hole, and a part of the power layer isolation area. In high speed PCB design, it is often necessary to use multi-layer PCB, and the hole is multi-original.An important factor in
PCB design surface should be coated with copper
Copper coating has advantages and disadvantages. PCB design for two layer board, high resistance loop, multilayer board (microstrip line), copper coating is very necessary. For multilayer high speed digital circuits with a complete power supply and ground
PCB boards often peel off the original size Reasons
A typical manufacturer can only request it twice per production cycle, and only check it once every few months. IR testing in simulated batches also prevents more spills of defective products, which are a prerequisite for quality PCB factories. In additio
Notes for avionics PCB development
Avionics and PCB board development requires special consideration and timely action to ensure that your design and manufacture meet aerospace industry standards.
