Customized solutions to meet your individual product requirements

According to the customer’s samples, we process various parts, perfect machinery, and equipment, and formulate reasonable plans. We start from the customer’s needs and design the products that the customer satisfy with.


The printed circuit board (PCB) is one of the two major parts manufacturing industries of the domestic electronics industry. With the vigorous development of the electronic information industry, the printed circuit board industry has grown faster. PCB ( Printed Circuit Board referred to the PCB ) according to a circuit design, the circuit components connected to the electric wiring pattern of the wiring will be formed, and then to design the specified machining, surface treatment, etc., on the electrical conductivity of the insulator body weight In other words, the printed circuit board is a substrate before being matched with electronic components.

The function of this type of product is to use the electronic circuit formed by circuit boards of various electronic parts to play the functions of various electronic components to achieve the purpose of signal processing.

Due to the good quality of printed circuit board design, it not only directly affects the reliability of electronic products, but also affects the overall performance and competitiveness of system products. The main function of the PCB is to provide mutual current connection of the various parts above.
