Tg250 PCB is made of polyimide material. It can withstand high temperature for a long time and does not deform at 230 degrees. It is suitable for high temperature equipment, and its price is slightly higher than that of ordinary FR4
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.
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.
