1. How does O-Leading guarantee quality? Supplier of hard gold plating
Our high quality standard is obtained with the following. 
1. The process is strictly controlled according to ISO 9001: 2008 standards. 
2. Extensive use of software in the management of the production process 
3. Cutting-edge testing tools and tools. For example. Flying Probe, X-ray Inspection, AOI (Automated Optical Inspector) and ICT (in-circuit test). 
4. Specified quality assurance team with failure case analysis process 
5. Training and continuous training of personnel 

2. How does O-Leading keep the competitive price? 
In the last decade, the prices of many raw materials (eg copper, chemicals) had doubled, tripled or quadrupled; The RMB Chinese currency had appreciated 31% against the US dollar; And our labor costs have also increased significantly. However, O-Leading has kept our prices constant. This is all about our innovations in reducing costs, avoiding waste and improving efficiency. Our prices are very competitive in the industry at the same level of quality. 
We believe in a win-win partnership with our customers. Our partnership will be mutually beneficial if we are able to provide you with an advantage in terms of cost and quality. 

3. What types of cards can the O-Leading process use? 
FR4 common, high TG and halogen-free boards, Rogers, Arlon, Telfon, aluminum / copper boards, PI, etc. 

4. What data are needed for PCB production? 
It is better to provide data in the Gerber 274-X format. In addition, Cam350, CAD, Protel 99se, PADS, DXP ​​and Eagle can also be processed. 

5. What is the typical process flow for multilayer PCBs? 
Cutting material → Internal dry film → Internal etching → Internal AOI → Multi-bond → Layer overlapping Pressing → Drilling → PTH → Plating → External dry film → Plating → External engraving → External AOI → Welding mask → Component mark → Finishing surface → Routing → E / T → Visual inspection.
