Product Overview
Multilayer PCBs (Multilayer Printed Circuit Boards) are high-density circuit boards composed of three or more conductive copper layers and insulating dielectric materials, precisely laminated together through a high-precision lamination process.
Compared with traditional single-layer or double-layer PCBs, Multilayer PCBs offer higher routing density, superior signal integrity, and better electromagnetic compatibility (EMC), making them suitable for complex electronic system integration.
In flexible electronics, Flexible Multilayer PCB combine multilayer circuit structures with flexible substrates, enabling bendable and foldable designs while maintaining high-density interconnection capabilities. They are widely used in space-constrained or dynamically moving devices.
Multilayer PCBs are widely applied in computers, communication equipment, medical electronics, and industrial control systems, serving as a core foundation for modern high-end electronic products.
