PCB Assembly (PCBA) Process
Step 1: Applying Solder Paste Using Stencil
Solder paste is applied to PCB areas where components will be placed using a stainless steel stencil. The paste (96.5% tin, 3% silver, 0.5% copper) creates strong joints when heated.
Step 2: Automated Placement of Components
Pick-and-place robots accurately position SMT components using preprogrammed X,Y coordinates from design files, ensuring precision and efficiency.
Step 3: Reflow Soldering
PCBs pass through an oven at 250°C to melt solder, creating permanent joints. Two-sided PCBs are processed one side at a time.
Step 4: Quality Control and Inspection
- Manual Inspection: Suitable for THT components and low-density boards
- Optical Inspection (AOI): High-speed automated inspection using multi-angle cameras
- X-ray Inspection: For complex PCBs to examine inner layer defects
Step 5: THT Component Fixation and Soldering
- Manual Soldering: Time-consuming but precise for through-hole components
- Wave Soldering: Automated process for single-sided PCBs with THT components
Step 6: Final Inspection and Functional Test
PCBs undergo electrical testing using oscilloscopes, DMMs, and function generators to verify all parameters meet design specifications.
Step 7: Final Cleaning, Finishing and Shipment
PCBs are cleaned with deionized water, dried with compressed air, and prepared for shipment.
