I. Pre-Production Preparation

• File Confirmation: Check and confirm the completeness and accuracy of the design files (Gerbers, BOM, PCB layout, etc.) provided by the customer.
• Spec Verification: Confirm key production specifications (layers, materials, surface finish, tolerance, etc.) with the customer to ensure consistency with their files.
• DFM Review: Conduct Design for Manufacturability (DFM) review based on the customer’s files to optimize production feasibility and avoid risks without changing the customer’s original design.

II. Bare Board Fabrication

• Layer Formation: Perform image transfer, etching and lamination on copper layers according to the customer’s layout files to form the core board structure.
• Drill & Plate: Drill holes and plate them with copper according to the hole position and size requirements in the customer’s files to achieve interlayer conduction (vias).
• Finish: Apply Solder Mask (for protection) and Surface Finish (for soldering) in accordance with the customer’s design files.
• E-Test: Conduct electrical testing on the bare board to check for short circuits and open circuits, ensuring compliance with the electrical requirements in the customer’s files.

III. Assembly and Validation (PCBA Finished Products)

• SMT: Print solder paste and automatically mount Surface Mount Components (SMCs) according to the customer’s BOM and layout files.
• Soldering: Fix components using reflow soldering (for SMT) or wave soldering (for THT) in accordance with the soldering parameters designed by the customer.
• Protection: Apply Conformal Coating if required by the customer’s files to protect the circuit board from moisture, dust and corrosion.
• FCT: Conduct comprehensive testing according to the customer’s functional requirements to ensure the normal operation of the finished PCBA products.

IV. Final Inspection & Delivery

• Final Quality Check: Inspect the finished PCBA products against the customer’s files and specifications to ensure no defects.
• Packaging & Delivery: Package qualified products as required by the customer and deliver them on time.
