PCB Knowledge:
According to the layout of the circuit module, the related circuit that realizes the same function is called a module. The components should adopt the principle of centralization in the vicinity. At the same time, the digital circuit and the analog circuit are separated.
Positioning hole, standard hole and other non-mounting holes within 1.27mm must not be soldered components, screws and other mounting holes within 3.5mm (for M2.5), 4mm (for M3) shall not be soldered to the components;
The distance from the outer side of the component to the edge of the board is 5 mm (Pcb Manufacturing)

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
