The Top 6 Trends in the PCB Manufacturing
PCBs from PCB manufacturers are often flat laminated composites comprised of non-conductive substrate materials with copper circuitry layers concealed within or on the exterior surfaces. They might be as basic as one or two layers of copper, or as complex as fifty layers or more in high-density applications. The flat composite surface is perfect for supporting the soldered and connected components to the PCB, while the copper conductors electrically connect the components. As substrates and components, PCBs may be made from several materials. Material selection is determined by the application's requirements, as different material choices give the circuits varying qualities that facilitate performance in specific circumstances. Designers may select materials depending on the electrical performance for high-speed applications, mechanical or thermal durability, or both - for example, automobile under-the-hood uses.
