SEHO Systems GmbH, a worldwide leading manufacturer of automated soldering systems and customer-specific solutions, has equipped the successful MaxiReflow soldering system with a new feature that will lead to remarkable time savings, thus contributing to reduced manufacturing costs. This particularly applies to production lines with frequently changing products that require completely different temperature profiles.
A major requirement for modern reflow soldering systems includes maintaining a consistent temperature level in the process zone, even with high-throughput and high-mass assemblies. An elaborate circulation of process gas and up-to-date insulation substantially reduces energy and nitrogen consumption.
Conversely, it is desirable to decrease the temperature in the process chamber to a significantly lower level when the production line changes to a product with different temperature requirements. Delaying times by 30-40 minutes is unacceptable when production is used to full capacity.
The new rapid chamber cooling feature can help reduce changeover time to a minimum. Upon changing the soldering program, the system automatically compares the nominal temperatures of the new program with the actual temperatures. If the new program’s temperatures are lower than a previously defined temperature delta, the system automatically starts the rapid chamber cooling function. When this happens, the hood opens automatically, the fans adjust to 100 percent, and an additional exhaust switches on to conduct the process heat in a controlled way to avoid excessive heating of the production hall.
The rapid chamber cooling function is activated and deactivated easily via internal software and the temperature delta is individually adjustable.
Since its foundation in 1973, SEHO has become the worldwide contact partner whenever soldering is involved. Company solutions are based on performance, flexibility, efficiency and technical progress. SEHO’s business activities and production organization are oriented according to the principles of sustained future-compatible development and production of machines. As a result, all applicable environmental standards are complied with meticulously. With its systems, the company provides customers with a sustained and resource economizing production facility. It continuously develops its technology in order to provide customers with a competitive advantage.
