Multilayer PCB
Multilayer PCBs are the core architecture of modern electronic design. They precisely laminate multiple conductive graphic layers onto insulating layers to form a highly integrated interconnected system. Their hallmarks are exceptional wiring density and robust interference immunity. Flexible stackup designs, ranging from 1 to 32 layers, allow for complex circuit functionality within a compact footprint within a board thickness range of 0.3 mm to 6 mm. With optional copper thicknesses ranging from 0.5 oz to 5 oz and a variety of surface finishes such as nickel-plated gold and tin-spraying, they ensure excellent electrical performance and long-term reliability. A minimum line/space width of 3 mils and a 10:1 aspect ratio further meet the demands of high-density packaging. Therefore, multilayer PCBs are not only the powerful heart of high-end communications equipment, automotive electronic control systems, and industrial computers, but also the key technological foundation for achieving high performance and compact size in cutting-edge fields such as aerospace and precision medical equipment.
