STEP 1
SMT Surface Mounting
High-speed placers mount micro-components onto PCBs with precision for miniaturized, high-density devices.
STEP 2
Reflow Soldering
High-temperature oven melts solder paste, firmly bonding SMT components with controlled thermal profiling.
STEP 3
AOI Automatic Optical Inspection
Optical imaging automatically scans PCBs to detect soldering shorts, misalignment, and defects.
STEP 4
DIP Insertion
Manual or semi-automatic placement of larger components, ensuring accurate positioning for thru-hole parts.
STEP 5
Wave Soldering
PCBs pass through a molten solder wave to bond component pins, with precise wave and temperature control.
STEP 6
PCBA Manual Soldering & Repair
Skilled technicians perform touch-ups and rework to guarantee stable electrical connections.
STEP 7
PCBA Functional Testing
Power-on testing verifies signal, voltage, and current performance, ensuring full compliance.
STEP 8
PCBA Aging Testing
Simulated harsh conditions (high temp) to identify latent flaws and ensure long-term reliability.
STEP 9
