The 6-layer Rigid-Flex PCB has the characteristics of FPC and PCB at the same time. Therefore, it can be used in some products with special requirements, including flexible areas and rigid areas. It is of great help to save the internal space of products, reduce the volume of finished products and improve the performance of products.
The 12-layer AP9222R Rigid-Flex PCB of flexible circuit board and Rigid circuit board is a kind of circuit board with FPC characteristics and PCB characteristics, which is formed by Rigid - Flex PCB together according to relevant process requirements through pressing and other processes.
FPC flexible board is a kind of flexible printed circuit board which is made of polyimide or polyester film with high reliability and excellent flexibility. It has the characteristics of high density, light weight, thin thickness and good bending property.
The 8-layer gold finger PCB is actually coated with a layer of gold on the copper clad laminate by a special process, because the gold has strong oxidation resistance and strong conductivity.
Ro4003c high frequency PCB--High frequency of electronic equipment is the development trend, especially in the development of wireless network and satellite communication, information products tend to be high-speed and high-frequency, and communication products are moving towards the standardization of voice, video and data of wireless transmission with large capacity and high speed. Therefore, high-frequency substrate is required for the new generation of products.
When the 40-layer M6G high speed PCB is close to the parallel high-speed differential signal line pair, in the case of impedance matching, the coupling of the two lines will bring many advantages. However, it is believed that this will increase the attenuation of the signal and affect the transmission distance.
