Overcome Complex PCB Challenge
Selective soldering technology provides a solution for handling complex PCB designs, especially excelling in high-density and mixed-assembly circuit board manufacturing.
- Precise Positioning: Selective soldering allows operations on specific soldering points without affecting nearby sensitive components, such as SMD devices or non-soldering areas.
- Nozzle Technology: Using the Ersa VERSAFLOW as an example, its wetted circular nozzle design ensures that solder flows evenly in very tight spaces, effectively avoiding bridging issues while ensuring high-quality solder joint connections.
- Flexible Soldering: Supports both single-wave and multi-wave soldering modules to meet the production needs of PCBs with varying design complexities.
Fewer Defects And Higher Reliability
Common soldering defects found in traditional wave soldering are significantly reduced with selective soldering.
- Precise Flux Application: Through micro-droplet application (such as the dual-nozzle configuration of the Ersa VERSAFLOW), flux is accurately applied to the solder joint area, preventing excess residue from contaminating non-soldering regions.
- Accurate Temperature Control: The preheating module can set temperature profiles according to PCB design requirements, minimizing component damage caused by temperature fluctuations. Additionally, the use of top heaters ensures better through-hole filling results.
- Anti-oxidation: The nitrogen atmosphere protects the solder from oxidation, thus improving the long-term stability and reliability of the solder joints.
Cost Savings in Material and Energy
Selective soldering technology optimizes material usage and production processes, leading to significant reductions in manufacturing costs.
- Less Solder Consumption: The miniaturized solder bath design (e.g., with a 10 kg capacity) helps avoid solder waste during dipping.
- Flux Reduction: Traditional atomization methods may lead to excessive flux, whereas selective soldering uses droplet spraying to precisely apply flux, reducing consumption and minimizing the need for cleaning processes.
- Efficient Energy Management: The modular, independent operation design shortens equipment cycle times, saving both space and energy costs.
