HDI PCB is the abbreviation of "high density interconnector", which is a kind of printed circuit board (PCB) production. It is a kind of circuit board with high line distribution density using micro blind buried hole technology.
The function of the Optical module PCB is to convert the electrical signal into optical signal at the sending end, and then convert the optical signal into the electrical signal at the receiving end after transmitting through the optical fiber.
8-layer rigid-Flex PCB has the characteristics of bending and folding, so it can be used to make customized circuit, maximize the indoor available space, use this point, reduce the space occupied by the whole system, the overall cost of rigid Flex PCB will be relatively high, but with the continuous maturity and development of the industry, the overall cost will continue to reduce, so it will be more cost-effective and competitive power.
The golden finger is composed of many golden yellow conductive contacts. It is called "golden finger" because its surface is gilded and the conductive contacts are arranged like fingers. The step 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.
The application scope of AP8555R Rigid-Flex PCB mainly includes: aerospace, such as high-end aircraft mounted weapon navigation system, advanced medical equipment, digital camera, portable camera and high-quality MP3 player.
Four layer EM-526 PCB is a kind of multilayer printed circuit board, which has both rigid layer and flexible layer. A typical (four layer) rigid flex printed circuit board has a polyimide core with copper foil on both sides.
