UL&IPC Standard & ISO
As the name suggests, a multilayer circuit board can only be called a multi-layer circuit board with more than two layers, such as four layers, six layers, eight layers, and so on. Of course, some designs are three-layer or five-layer circuit, also called multi-layer PCB circuit board.
Conductive wiring diagram larger than the two-layer board. The insulating substrate is separated between the layers. After each layer of the circuit is printed, each layer of the circuit is overlapped by pressing. After drilling, the electrical connection between them is usually achieved through plated through holes on the cross section of the circuit board.
As one of the leading Printed Circuit Board manufacturers based in China, Ucreate has been offering international companies of all sizes with high-quality PCB prototype to production services at a fair price for eight years. To make professional and advanced circuit boards, we're committed to adhering to the strictest standards during the PCB manufacturing process. We're fully compliant with the ISO 9001:2008 quality management system.
