The Production Process – Rigorous Quality at Every Stage
Stage 1: Order Receipt & Engineering Review
Your order is received; design files, BOM, and specifications are reviewed. DFM analysis identifies potential quality issues before production.
Stage 2: Component Procurement
We source components through authorized distributors. Incoming inspection includes LCR testing, visual verification, and Brand authenticity verification. Only verified components enter production.
Stage 3: PCB Fabrication
In-house bare board creation with controlled processes. Material certifications and dimensional verification ensure quality from the start.
Stage 4: SMT & THT Assembly
12 automated SMT lines with ±25μm accuracy. Real-time process monitoring ensures consistent placement. Automatic wave soldering and robotic soldering provide reliable joints.
Stage 5: Quality Inspection (100% Coverage)
Every board undergoes comprehensive inspection. Any defect detected at any assembly phase is identified and corrected. Root cause analysis prevents recurrence.
Stage 6: Final Assembly & Shipping
Board integration, component connection, final verification. Professional packaging, customs clearance, and shipping with tracking.
