Enhanced cooling zone contamination control for improved reliability and reduced maintenance
In nitrogen reflow soldering, managing flux residues is critical to maintaining oven performance and product quality. While traditional systems rely only on heat exchangers to collect contaminants, they often may require maintenance and cause unplanned machine downtime. Vitronics Soltec’s new CoolClean option offers a more advanced solution for nitrogen reflow ovens equipped with CATHOX technology. Unlike conventional methods, CoolClean actively extracts contaminated gases from the slot exhaust and the first cooling zone, condensing them on a heat exchanger located outside the process area.
This design minimizes flux residue buildup inside the oven, prevents dripping onto PCBs, and significantly reduces overall contamination. During the reflow process, flux residues—along with solvents, organic acids, and solder mask by products—tend to accumulate, especially in cooling zones. Traditional systems often struggle to manage these contaminants effectively, resulting in unplanned maintenance and potential disruptions. CoolClean addresses this challenge by relocating the condensation process outside the oven, ensuring cleaner operation, enhanced reliability, and reduced maintenance needs
Designed for compatibility with CATHOX-equipped nitrogen ovens, CoolClean is also field-upgradeable, making it a simple and effective way to boost uptime and process efficiency.
Key features and benefits summary:
• Removes contaminated gases before they drip onto PCBs or build up inside the oven.
• Extends maintenance intervals and reduces the requirement for frequent cleaning.
• Compatible with nitrogen reflow ovens using CATHOX technology
• Compatible with all solder paste types.
• Equipped with temperature and flow sensors to predict and detect maintenance needs.
• Easy access.
