In the field of communication electronics, telecommunication PCB boards are widely used in wireless networks, transmission networks. broadband data communication and fixed network telecommunication broadband. Related PCBs usually include: backplane PCBs, high-speed multi-layer PCBs, high-frequency microwave PCBs and multifunctional metal core PCBs.
42% telecommunication PCB boards are 8-16 layer PCBs. Mobile terminal are mainly HDI and flexible board.
With the apply of 5G communication technology, the frequency of electronic products is getting higher and higher, which requires the printed circuit board not only has electrical connection , but also signal transmission. Signal transmission loss should be paid attention to. When we manufacture the circuit board, we need to use materials with low DK and DF values. It is necessary to change the resin and add middle PP or other materials.
