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.
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.
The heat resistance of the Robot 3step HDI PCB is an important item in the reliability of HDI. The thickness of the Robot 3step HDI Circuit Board becomes thinner and thinner, and the requirements for its heat resistance are getting higher and higher. The advancement of the lead-free process has also increased the requirements for the heat resistance of HDI boards. Since the HDI board is different from the ordinary multilayer through-hole PCB board in terms of layer structure, the heat resistance of the HDI board is the same as that of ordinary multilayer through-hole PCB board is different.
High-frequency substrates, satellite systems, mobile phone receiving base stations and other communication products must use high-frequency circuit boards, which will inevitably develop rapidly in the next few years, and high-frequency substrates will be in large demand. The following is about Astra MT77 PCB related, I hope to help you better understand Astra MT77 PCB.
28-Layer 3step HDI PCB While electronic design is constantly improving the performance of the whole machine, it is also trying to reduce its size. In small portable products from mobile phones to smart weapons, "small" is a constant pursuit. High-density integration (HDI) technology can make the design of end products more compact while meeting higher standards of electronic performance and efficiency. The following is about 28 Layer 3step HDI Circuit Board related, I hope to help you better understand 28 Layer 3step HDI Circuit Board.
24-Layer Buried capacitance PCB has a process called burying resistance, which is to put chip resistors and chip capacitors into the inner layer of the PCB board. These chip resistors and capacitors are generally very small, such as 0201, or even smaller 01005. The PCB board produced in this way is the same as a normal PCB board, but a lot of resistors and capacitors are placed in it. For the top layer, the bottom layer saves a lot of space for component placement. The following is about 24 Layer Buried capacitance PCB related, I hope to help you better understand 24 Layer Buried capacitance PCB.
