PCB design service process

1. Customers provide schematic diagrams to consult PCB design;

2. Evaluate the quotation according to the schematic diagram and customer design requirements;

3. The customer confirms the quotation, signs the contract, and prepays the project deposit;

4. Receive advance payment, arrange engineer design;

5. After the design is completed, provide a screenshot of the file to the customer for confirmation;

6. The customer confirms OK, settles the balance, and provides PCB design information.
