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.
Through a series of inspections, tests and aging tests and other technical means, the PCB can be guaranteed to work reliably for a long time (usually 20 years).
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.
Printed Circuit Board: PCB (Printed Circuit Board); Flexible attached Circuit Board: FPC or FPCB; Soft and hard Board: RFPC or RFPCB (Rigid Flex Printed Circuit Board), as the name implies, is both hard Board and soft Board characteristics of a new line Board.
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!
