EM-888 7MM Thick PCB--As user applications require more and more board layers, alignment between layers becomes very important. Alignment between layers requires tolerance convergence. As the board size changes, this convergence requirement is more demanding. All layout processes are generated in a controlled temperature and humidity environment. The following is about EM888 7MM Thick PCB related, I hope to help you better understand EM888 7MM Thick PCB.
Tachyon 100G PCB The exposure equipment is in the same environment. The alignment tolerance of the front and back images of the entire area must be maintained at 0.0125mm. The CCD camera is required to complete the front and rear layout alignment. After etching, the four-hole drilling system was used to perforate the inner layer. The perforation passes through the core board, the position accuracy is maintained at 0.025mm, and the repeatability is 0.0125mm.

In addition to the requirement for uniform thickness of the plating layer for drilling, backplane designers generally have different requirements for the uniformity of copper on the surface of the outer layer. Some designs etch few signal lines on the outer layer. The following is about Megtron6 step PCB related, I hope to help you better understand Megtron6 step PCB.
For general frequency, use FR-4 sheet, but high-frequency materials should be used in the frequency ratio of 1-5G, such as semi-ceramic materials. ROGERS 4350, 4003, 5880, etc. are commonly used ... If the frequency is higher than 5G, it is best to use PTFE material, which is polytetrafluoroethylene. This material has good high-frequency performance, but there are limitations in the processing arts, such as the surface technology that cannot be hot air leveled.

The frequency of vehicle millimeter wave radar is mainly divided into 24GHz frequency band and 77GHz frequency band, of which 77GHz frequency band represents the future trend. The reliability of 77G radar board is very important. It is related to the safety of car driving. Among them, the reliability of electroplating is the most important factor affecting its reliability. The following is about Car Collision Avoidance Radar PCB related, I hope to help you better understand Car Collision Avoidance Radar PCB.
The aperture ratio of PCB is also called the ratio of thickness to diameter, which refers to the thickness of the board / aperture. If the aperture ratio exceeds the standard, the factory will not be able to process it. The limit of the aperture ratio cannot be generalized. For example, via holes, laser blind holes, buried holes, solder mask plug holes, resin plug holes, etc. are different. The aperture ratio of the via hole is 12: 1, which is a good value. The industry limit is currently 30: 1. The following is about 8MM Thick PCB related, I hope to help you better understand 8MM Thick PCB.
