Halogen-free PCB -- halogen (halogen) is a group VII a non-gold Duzhi element in Bai, including five elements: fluorine, chlorine, bromine, iodine and astatine. Astatine is a radioactive element, and the halogen is usually referred to as fluorine, chlorine, bromine and iodine. Halogen-free PCB is environmental protection PCB does not contain the above elements.
As TU-768 Rigid-Flex PCB design is widely used in many industrial fields, in order to ensure a high first-time success rate, it is very important to learn the terms, requirements, processes and best practices of rigid flex design. TU-768 Rigid-Flex PCB can be seen from the name that rigid flex combination circuit is composed of rigid board and flexible board technology. This design is to connect the multilayer FPC to one or more rigid boards internally and / or externally.
TU-768 PCB refers to high heat resistance.General Tg plates are above 130 ° C, high Tg is generally more than 170 ° C, and medium Tg is about more than 150 ° C. Generally, Tg≥170 ° C PCB printed board is called high Tg printed board.
HDI boards are generally manufactured using a lamination method. The more laminations, the higher the technical level of the board. Ordinary HDI boards are basically laminated one time. High-level HDI adopts two or more layered technologies. At the same time, advanced PCB technologies such as stacked holes, electroplated holes, and direct laser drilling are used. The following is about 8 Layer Robot HDI PCB related, I hope to help you better understand 8 Layer Robot HDI 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.
