Frequently Asked Questions

What is the difference between PCB manufacturing and PCB assembly?

PCB manufacturing refers to the production of bare circuit boards, while PCB assembly (PCBA) involves mounting components (SMT/DIP) onto the board to create a functional electronic unit.

Do you support prototype and small-batch production?

Yes, we offer express prototype PCB assembly and support low-volume to high-volume production with flexible MOQs.

How do you ensure component authenticity?

We follow AS6081 standards, use three-stage quality control, and source from authorized distributors to prevent counterfeit components.

What file formats do you accept for PCBA?

We accept Gerber files, BOM (Bill of Materials), Pick & Place files, and assembly drawings in standard formats.
