UL E253641 2L&Multilayer Printed Circuit Board PCB
The first step is to get a PCB; it records the models, parameters, and position of all the elements on the paper, especially the diode, the direction of the three tubes, and the direction of the IC gap. It is best to take two photos of the location of the element with a digital camera.
We always hold a 'magnifying glass' in work, and we are meticulous about each node, each process, and each place that needs to be inspected or paid attention to, ensuring our pcb and pcba, fr4 circuit board, computer circuit board maintaining in excellent quality. As a company that wants to establish a brand image, customers are the foundation of our existence, and customer maintenance is the top priority of development. We exploit larger marketing channels wholeheartedly, expand market share, tap potential business opportunities, trying to develop and grow together with our partners. We respect talents and focus on technology with the spirit of stability, development, loyalty, efficiency, unity and innovation.
The copper clad reduces the heating surface of copper and plays the role of electromagnetic shielding. But it should be pointed out that the grid is made up of interlaced lines, and we know that for circuits, the width of the wiring has a corresponding "electrical length" to the circuit board's working frequency, when the working frequency is not very high. Perhaps the effect of grid lines is not obvious, once the electrical length and frequency match, it is very bad. You will find that the circuit is simply not working properly and signals are being transmitted everywhere to interfere with the system's work. Therefore, for the use of the grid, it is suggested that the design of the circuit board can be selected according to the working situation.(multilayer pcb)
Process of pcb manufacturing:
Our Company is UL,ISO9001,ROHS and GJB9001B certified.
Packing and Shipping:
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
