PCB Knowledge:
Multi-layer PCB board refers to a circuit board with more than three layers, which is formed by laminating a series of double-layer or multi-layer circuit boards. These boards are joined together with special glue to ensure that excess heat does not melt any parts. Multilayer printed circuit boards come in a variety of sizes, and can have four, ten, or twelve layers.
Multilayer printed circuit board requires designers to make very complex designs for a variety of complex electrical tasks. Multilayer PCBs are widely used in applications such as file servers, data storage, GPS technology, satellite systems, weather analysis, and medical equipment.

FAQ:
1. How to Get a quotation?
For PCBs,pls send us the Gerber File.For PCBA,pls send us the Gerber file and BOM(Bill of Materials)
2. What is the MOQ?
No MOQ.1 pcs is ok.
3.What is the lead time?
For PCB orders,the lead time is 2 to 10 days.For PCBA orders,the lead time will be 15 to 30 days.
4.Will the boards be tested before shippment?
Yes,all PCBs will be tested by Flying Probe or E-test.For PCBA,we will have AOI,X-ray,and functional test.
