China flex rigid pcb manufacturer Manufacturers

The lives of modern people are increasingly inseparable from electronic products, and copper foil is its base. The 6-micron thick copper foil breaks through the existing technology, and its future will penetrate into all aspects of life.

The high-frequency circuit board includes a core board provided with a hollow groove and a copper clad laminate adhered to the upper and lower surfaces of the core board by flow glue.

DFM (Design for Manufacturing) is the most effective way to ensure the quality of PCB SMT processing. DFM is a design practice and process that matches the engineering requirements of a product with global manufacturing capabilities to achieve the lowest cost, highest output, and speed up time to market. DFM considers manufacturability and testability from the time of product development and design, so that the design and manufacturing are closely linked to achieve the goal of one-time success from design to manufacturing. DFM has the advantages of shortening the development cycle, reducing costs, and improving product quality. It is the way for enterprises to achieve success.

A rigid PCB is the most traditional form of board in the PCB world. Common multi-layer PCB circuit boards are generally 4-layer boards or 6-layer boards, and complex multi-layer boards can reach more than a dozen layers. There are both high-speed logic circuits and linear circuits on the circuit board. They should be separated as much as possible, and the ground wires of the two should not be mixed, and they should be connected to the ground wires of the power supply. To maximize the ground area of the linear circuit. So how should the PCB circuit board be maintained?

Some PCBA processed products may encounter white spots. White spots usually occur during welding or post-welding cleaning, and are mainly manifested as white spots or white residues on or around the surface of PCB, pin and solder joint.
