What is PCB Board

Printed circuit board is one of the important parts of the electronics industry. Almost every kind of electronic equipment, from electronic watches to computers and military weapon systems, as long as there are electronic components such as integrated circuits, PCB  circuit boards must be used in order to make electrical interconnections between the various components.

The PCB printed circuit  has good product consistency, and it can adopt standardized design, which is conducive to the realization of mechanization and automation in the production process.

The reason why PCB products can be used more and more widely is because it has many unique advantages, which are roughly as follows:

PCB board Manufacturing Steps

Inner layer graphics production
Inner layer graphics detection




Surface treatment
Solder mask
Outer graphics detection
Outer graphics production
Plate plating
Immersion copper

Electrical Test

Appearance inspection


What Are PCB Board Made Of?

Insulating laminate composed of polymer synthetic resin and reinforcing material can be used as the substrate of copper clad laminate. There are many kinds of synthetic resins, commonly used are phenolic resin, epoxy resin, polytetrafluoroethylene and so on. Reinforcement materials generally have two types: paper and cloth, which determine the mechanical properties of the substrate, such as solder dip resistance and bending strength. According to raw materials, there are usually
The key material for the manufacture of copper-clad plates must have high conductivity and good weldability. According to ministerial standards, the nominal series of copper foil thickness are 18, 25, 35, 70 and 105um. my country is currently gradually promoting the use of 35um thick copper foil. The thinner the copper foil, the easier it is to etch and drill, which is especially suitable for manufacturing high-density printed boards with complex circuits.
The adhesive is an important factor in whether the copper foil can be firmly covered on the substrate. The peel strength of the copper clad laminate mainly depends on the performance of the adhesive. 4. Board thickness: usually refers to the requirements of the finished product, respectively, 0.6mm, 0.8mm, 1.0mm, 1.2mm, 1.6mm, etc
