About Multilayer PCB

With the increasing complexity of circuit design, in order to increase the area of wiring, multilayer PCB can be used. Multilayer board is a PCB that contains multiple working layers. In addition to the top and bottom layers, it also includes signal layer, middle layer, internal power supply and ground layer.
The number of layers of PCB represents that there are several independent wiring layers. Generally, the number of layers is even and includes the outermost two layers. Because it can make full use of multilayer board to solve the problem of electromagnetic compatibility, it can greatly improve the reliability and stability of the circuit, so the application of multilayer board is more and more widely.

Transaction process

1.Send information (customer send Gerber / PCB file, process requirement and quantity of PCB to us)

2.Quotation (the engineer reviews the documents, and the marketing department makes quotation according to the standard.)

3.Place an order (the customer provides the company name and contact information to the marketing department, and completes the payment)

4.Delivery and receiving (put into production and deliver goods according to the delivery date, and customers complete the receiving)
