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.
Polyimide products are highly demanded due to their huge heat resistance, which leads to their use in everything from fuel cells to military applications and printed circuit boards. The following is about VT901 PCB related, I hope to help you better understand VT-901 PCB.
