For most circuit board manufacturers, the most contacted are three conventional classifications. For example: single-layer circuit board, double-layer circuit board. Multilayer circuit boards, about their other special processes, will not go into too much detail today.
single layer circuit board
Single-sided circuit board PCB is also called single-sided board (Single-sided). This kind of circuit board is relatively conventional and simple. Basically, circuit board processing manufacturers can produce it. Because only one side has wiring, we call it single-sided. Laminates.
double layer circuit board
This kind of circuit board is different from the single-layer board in that it has wiring on both sides, but to use the wires on both sides, there must be a proper circuit connection between the two sides. At present, this kind of board is produced by small and medium-sized manufacturers in the market, and the production process is relatively simple.
multilayer circuit board
The previous simple boards could no longer meet the needs of the recent development of electronic products. At this time, high-precision kiln circuit boards began to be born with the development of electronic equipment. When multi-layer boards meet more complex application requirements, the circuits can be arranged. Form a multi-layer structure and press them together, and build through-hole circuits between the layers to connect the circuits of each layer.
