Ersa | In-line melting furnace with vacuum | EXOS 10/26

With the EXOS 10/26, Ersa presents a convection reflow soldering system with 22 heating zones and four cooling zones, as well as a vacuum chamber after the peak zone, with which the void rate can be reduced by 99%. This is achieved by relying on technologies proven thousands of times in HOTFLOW models, such as heating and cooling or cooling zones or the intuitive, award-winning interface.
Thanks to intelligent features, the Ersa welding system produces particularly economical and void-free welds. In addition to process reliability, the EXOS is particularly easy to maintain. For energy-efficient cooling, three expansion stages are available for the EXOS (a maximum of four cooling zones at the top and bottom), so that optimum cooling gradients can be set for all requirements..

How to avoid the formation of Voids? Ersa EXOS 10/26

A challenge for SMD soldering is voids that reduce solder quality. They can even lead to component failure. The rate of voids can be reduced by applying a vacuum at the moment the solder becomes liquid. By striving for pressure compensation, voids migrate to the negative pressure area, thus leaving the solder joints.
Aspectos destacados EXOS 10/26:

• 4-zone conveyor (feed, preheating and peaking, vacuum, cooling zone) also as a two-way conveyor.
• Perfect synchronization of assemblies and transitions thanks to sensorized conveyor, without the need for an external power supply module.
• The roller conveyor requires almost no maintenance and no lubricant in the vacuum module..
• Optimum access to the vacuum chamber via the lifting unit from above
• Optimal temperature profiles through medium-wave emitters in the vacuum module
• Maximum machine availability due to quick removal of the conveyor unit in the vacuum module
• Vacuum pump integrated in a separate module holder for easy and fast maintenance
• Innovative SMART ELEMENTS® Cleaning System
