PCB Knowledge:
Of all surface treatments, HASL (lead free / no lead free) is the most common and cheapest treatment, but note the RoHS rules of the European Union.
RoHS: RoHS is a mandatory standard established by EU legislation. Its full name is《 the Directive on restricting the use of certain harmful components in Electronic and Electrical equipment》 (Restriction of Hazardous Substances). The standard has been put into practice since July 1, 2006. It is mainly used to standardize the materials and process standards of electronic and electrical products so as to make them more favorable to human health and environmental protection. The aim of the standard is to eliminate six substances, namely lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products. The content of lead should not exceed 0.1%.(Pcb Fabrication)

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
