China hdi pcb design guidelines Manufacturers

With the development of science and technology, PCB board precision (aspect ratio) requirements are increasingly high, it not only brings trouble to PCB manufacturers (cost and quality conflict), but also to the downstream customers buried serious quality hidden trouble! In the following section of the circuit board manufacturers xiaobian and everyone together to understand, hope to the relevant colleagues have inspiration and help!

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.

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.

Rigid-Flex Boards have become one of the most influential innovations in the printed circuit board (PCB) industry, enabling compact, reliable, and high-performance electronic products. By combining rigid PCB sections with flexible circuit layers into a single integrated structure, Rigid-Flex Boards eliminate connectors, improve signal integrity, and unlock new design freedom for engineers.

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.

The advantages are: smaller size, higher capacity density, low temperature resistance, and better cycle performance.
