| Soldering Parameter | Studio's Control | Why It Matters |
|---|---|---|
| Reflow Profile | Customized per BGA package; controlled ramp, soak, and peak zones | Prevents thermal damage; ensures proper wetting |
| Stencil Design | Optimized aperture geometry; laser-cut stencils | Consistent paste volume; prevents bridging |
| Placement Pressure | Controlled placement force; ±25μm accuracy | Prevents ball damage; accurate alignment |
| Nitrogen Reflow | Available for critical BGA applications | Reduces oxidation; improves wetting |
| Cooling Rate | Controlled cooling rate | Prevents thermal shock; reduces voiding |
| X-Ray Verification | 100% inspection; automated void analysis | Confirms solder joint quality; documents results |
Stage 1: Engineering Review & Process Optimization
Professional engineering review of BGA type, board construction, and layout. Reflow profile development and stencil design optimization.
Stage 2: Component Procurement
Components sourced through authorized distributors. For low volume PCB assembly, small-quantity procurement supported. Incoming inspection verifies component integrity.
Stage 3: Precision Solder Paste Printing
Laser-cut stencil with optimized aperture design. 3D SPI verifies paste volume, height, and area.
Stage 4: Professional BGA Placement
12 SMT lines with advanced BGA placement capability. Vision alignment ensures accurate ball-to-pad registration. ±25μm accuracy.
Stage 5: Controlled Reflow Soldering
Custom reflow profiles per BGA type. Closed-loop temperature control; nitrogen reflow option. Real-time process monitoring.
Stage 6: 100% X-Ray Inspection
Every BGA board undergoes comprehensive X-Ray inspection: 2D X-Ray for ball position; 3D X-Ray for void analysis. Automated void calculation per ball. IPC Class 2/3 standards supported.
Stage 7: Quality Testing & Final Assembly
ICT, Flying Probe, FCT testing. AOI for visible components. Professional packaging and global shipping.
| Skill Requirement | Studio's Professional Capability |
