Laser Soldering Comparison
Solder Wire
- Fluxless soldering
- Higher precision solder volume control by solder ball nature
- Lower thermal stress
Stencil Printing
- Fluxless soldering
- Higher precision solder volume control by solder ball nature
- Lower thermal stress
Ball Drop
- Fluxless soldering
- No stencil required
- Support multiple solder alloy on same wafer
- Cheap and flexible process for R&D and prototyping
- Lower thermal stress
- Ball placement on surface with topography
- No additional reflow after ball placement
Mini Wave Soldering / Selective Soldering
- Fluxless soldering
- Higher precision solder volume control
- Higher selectivity
- Better flexibility against more complex terrain
