Pcb Making

Because the layers of the PCB are tightly combined, it is usually not easy to see the actual number, but if you look closely at the card faults, you can still tell them. The observation found that PCB had a layer or layers of white substance in the middle.

PCB Knowledge:

It can be said that the number of PCB layers is related to the production cost, the reduction of the number of PCB layers can greatly reduce the cost, and this price difference is also very different. The number of PCB layers increases twice the cost of each two layers. Therefore, the number of PCB layers has a very large role in cost control. In any case, judging the number of layers of PCB is a skill that must be mastered. Here are a few ways to determine the number of PCB layers.

Because the layers of the PCB are tightly combined, it is usually not easy to see the actual number, but if you look closely at the card , you can still tell them.If you check carefully you will find that PCB had a layer or layers of white substance in the middle. This is the insulation layer between the layers, which is used to ensure that there is no short circuit between the different PCB layers. Because the multilayer PCB boards use more single or double-sided tracing boards, and a layer of insulation is placed between each layer and pressed together, the number of layers of the PCB board represents the number of tracing layers. The insulation between layers becomes the most intuitive way to judge the number of layers of PCB.

The "guide hole" on PCB is used to identify the number of PCB layers. The principle is mainly due to the multilayer PCB circuit connection using the guide hole technology. How many layers are there in PCB, we can identify them by observing the guide hole.(pcb making)

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
