The standard PCB board is a general term for all printed boards, which can be divided into single-layer boards or multi-layer boards as required. The substrate of the board itself is made of an insulating, non-bendable material. You can see that on the surface
The wiring material is copper foil. Originally, the copper foil is covered on the whole board, but in the manufacturing process, the middle part is etched away, and the remaining part becomes a network of small lines. These lines are called conductors
pattern) or wiring, and used to provide circuit connection of parts on PCB. The PCB board is V-CUT
PCB, that is, there are several boards in a board, not a single out. Plate shipment is roughly the same, mold out of the plate when a four, six, eight and so on. Not single out to facilitate the production of SMD components.
Double-sided PCB board
Double-sided PCB board is a very important PCB board in the circuit board, the market has double-sided circuit board metal base PCB board, Hi-Tg heavy copper foil circuit board, flat winding double-sided circuit board, high frequency PCB, mixed dielectric base high frequency double-sided circuit board, etc. It is suitable for a wide range of high-tech industries such as: telecommunications, power supply, computer, industrial control, digital products, scientific and educational instruments, medical instruments, automobiles, aerospace defense and so on.

The difference between double-sided PCB board and single-sided PCB board is that the single-panel circuit is only on one side of the PCB board, while the double-sided PCB circuit can be in the two sides of the PCB board, with holes in the middle to connect the double-sided PCB board circuit. Parameters of double-sided PCB board In addition to the production process of double-sided PCB board is different from that of single-sided PCB board, there is also a copper sinking process, that is, the process of double-sided circuit conduction.
