Double Sided PCB

The double-sided PCB is more complicated than single-sided PCB. The circuit patterns, on its both sides, are connected through a through hole in the middle. Various types of double-sided PCB are in the market, such as double-sided metal base 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.

  • Why is the Color of PCB Mostly Green?

    The color of PCB surface is actually the color of solder resist, which can prevent the wrong soldering of components, prolong the service life of devices, and prevent the oxidation and corrosion of de...

The production process of double-sided PCB

Double-sided 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 double-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-sided PCB

  • It makes it relatively easy to add conductive paths on the board, which means you will have a PCB that better suits your needs.

  • As both sides are conductive, a large number of ICs and components can be assembled at any time.

  • You can add more components as needed as there is an extra layer.

  • More space and flexible design allow the PCB to suit your requirements.

  • Double-sided PCB is ideal for demanding applications and advanced electronics.

  • If necessary, the size of the double-sided PCB can be reduced, because double sides can be used.

  • This type of PCB may save you money because you may only need one.

  • 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

  • Appearance. A single-sided PCB only has one layer, but the double-sided PCB has 2 layers, with via hole connecting double-sided PCB circuit.

  • Different production processes. The two-sided PCB has a copper sink process, which is for the two-sided circuit conduction.
