More possibilities. More flexibility. More process area.

The UniTemp RSS Series is expanding – now featuring the new RSS-310-SC!

Whether for research and development, prototype manufacturing, or small-batch production: precise and reproducible soldering processes are crucial for the quality of modern electronic assemblies and semiconductor components.

With the RSS series, UniTemp offers compact, high-performance vacuum reflow soldering systems tailored to a variety of requirements and substrate sizes.

New since 2026: The RSS-310-SC expands the RSS Compact family and opens up new possibilities with a process area of up to 310 × 310 mm². UniTemp now offers a particularly versatile selection of compact vacuum reflow systems – ranging from the RSS-160-SC to the RSS-210-SC and the new RSS-310-SC.

Three models. A strong product family.

The new model combines the compact system design of the RSS family with a significantly larger processing area.

Sophisticated technology for reliable processes

All three models in the RSS Compact family are designed for precise and controlled process management. Key features include:

• SIMATIC® controller: Intuitive operation via a 7-inch touch panel.
• Vacuum technology: Evacuation of the process chamber down to 10⁻³ hPa for reproducible process conditions.
• Process gas control: Mass flow controllers for the controlled supply of nitrogen and other inert gases.
• Precise temperature profiles: Individually programmable processes with up to 50 storable programs.
• Efficient cooling: Water-cooled process chamber and substrate cooling for controlled cooling rates.
• Process monitoring: Viewing window for visual monitoring of the soldering process.

Versatile applications

The RSS series is designed for numerous thermal applications in microelectronics. These include, for example:

• Fluxless soldering
• Flip-chip processes
• Solder bump reflow
• Adhesive and bonding processes
• Encapsulation of packages
• Soldering of power semiconductors
• Heat treatment of semiconductor wafers
• Prototype development and quality control

In particular, when combined with a vacuum and suitable process gases, it is possible to achieve precise and reproducible brazing conditions.

Quality and Engineering – Made in Germany

UniTemp develops and manufactures its systems using its many years of expertise in thermal process technology. Nearly all mechanical components are produced in the company’s own workshop. Software development is also carried out in-house and is based on SIMATIC® control technology.

This not only ensures high manufacturing quality but also allows for great flexibility in meeting individual customer requirements and providing custom solutions.
