Double Sided PCB

PCBA is a process requiring knowledge covering PCB manufacturing assembly, PCB design, fabrication and a strong understanding of the final product. ZF is a professional pcb manufacturing companies with high-quality, all of our products have obtained ISO9001, ISO13485: 2016, IATF16949: 2016, IPC-A-610E, UL, RoHS certifications.

The double layer pcb china(double-layer/double-sided printed circuit board/breadboard) is more complicated than single sided PCB. The circuit patterns, on both sides, are connected through a through-hole in the middle. Various types of double-sided PCB are on the market, such as double sided copper clad PCB, high Tg thick copper foil PCB, high-frequency PCB, and hybrid dielectric base high-frequency double-sided PCB. Double-sided PCBs are widely used in high-tech industries like telecommunications, power supply, computers, industrial control, digital products, scientific and educational equipment, medical equipment, automobiles, aerospace defense.

The production process of double sided PCB

Double-sided or 2 layer PCB is usually made of epoxy glass cloth copper-clad laminates. It is mainly used for communication electronic equipment, advanced instruments, and electronic computers with high-performance requirements.

The production process of two sided PCB can be generally divided into several methods, such as process wire method, hole plugging method, masking method, and pattern plating-etching method.

Advantages of double layer PCB

As one of the professional PCB fabrication companies in China, ZF Electronics will introduce some features of double layer printed circuit board:

108. It makes it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs.
108. As both sides are conductive, a large number of ICs and components can be assembled at any time.
108. You can add more components as needed as there is an extra layer.
108. More space and flexible design allow the PCB to suit your requirements.
108. Dual layer PCB is ideal for demanding applications and advanced electronics.
108. If necessary, the size of the double-sided PCB can be reduced, because double sides can be used.
108. This type of printed circuit board for sale may save you money because you may only need one.
108. Double-sided PCBs can be used in many different applications and electronic products, suitable for a wide range of industries.

The difference between double sided PCB and single sided PCB

108. Appearance: A single sided circuit board only has one layer, but the double-sided PCB has 2 layers, with a via hole connecting double sided PCB circuit.
108. Different production processes: The 2 sided PCB has a copper sink process, which is for the two-sided circuit conduction.
