• Printed circuit technology makes mass production of electronic equipment simple and easy, and lays the foundation for mechanized and automated production of electronic products. Since the 1950s, the substantial progress made in various electronic products, including communication equipment, is inseparable from the use of printed circuit technology.
• With the continuous improvement of the manufacturing level of printed circuits, the printed circuits produced can achieve high precision, thus pushing the production and manufacturing of circuit boards to a new stage. When making plates in the printing industry, a large picture can be reduced to a certain size by shooting. When manufacturing printed circuits, it is also possible to reduce the electronic circuit diagram to make a plate, making it an electronic circuit board with a small area, complex circuits and high reliability. This printed circuit board is very suitable for communication equipment and computers with complex circuits and high reliability requirements. The development of printed circuit technology laid the necessary technical foundation for the subsequent invention of integrated circuits.

American military MIL standard.The company has attained the UL security certification, ISO9001-2000 quality system certification and ISO14001 environmental system certification.

• 6.SECURITY EQUIPMENT
• Whether in homes, businesses, or government buildings, manyaspects of security systems rely on PCBs.They play more rolesin our safety and security than many realize.

Double sided printed circuit board (PCB) is a common type of printed circuit board.
It has conductive patterns on both sides, which connect different layers of circuits through metalized holes (also known as vias). These vias enable signals to be transmitted between the two sides of the circuit board, making the layout of the circuit more flexible. Widely used in electronic products, such as computer motherboards, both sides can be wired, greatly increasing the way and density of component connections, thereby enabling more complex circuit functions. Its production process is relatively complex, including multiple steps such as inner layer graphic production, inner layer etching, drilling, copper plating, etc.
