Inquire About This Product
basic information
Generally, high-density multilayer lamination technology is adopted in manufacturing. It increases the available wiring area and enhances wiring density. It reduces the thickness of the insulating medium, thereby decreasing the overall thickness and weight of the printed circuit board. It shortens the length of wire interconnections, reducing electrical signal interference and loss. The relatively small thickness of the vias improves the reliability of interconnections. The structural design of the vias is convenient, allowing for greater design flexibility and improved design efficiency.
