SEEKPCB will carefully check the data from customers, including PCB data, BOM and specific assembly test requirements. The engineer will give the customer the questions about materials for confirmation. After confirmation, the engineer will also provide the overall quotation for PCB production, material procurement and PCB assembly. After confirming the price, the customer provides the purchase order and arranges the purchase payment for the corresponding materials. After that, SEEK will arrange the purchase of materials and PCB production at an appropriate time. PCB production problems still refer to the PCB cooperation process. After all the materials are ready, SEEK will arrange the assembly and testing, and finally pack and ship to the customer.
