Our 5-Step Turnkey PCBA Process

Step 1: Free DFM & DFA Review

Every order begins with a complimentary Design for Manufacturability and Design for Assembly review. Our engineers analyze your Gerber files and BOM to catch footprint mismatches, trace width issues, and stack-up problems before a single component is placed—saving you costly respins.

Step 2: Smart Component Sourcing & Procurement

Step 3: Precision SMT & THT Assembly

Step 4: Rigorous Multi-Stage Quality Inspection

Step 5: Programming, Testing & Delivery
