Modern electronics manufacturing requires technologies with high reliability. By using formic acid in convection, condensation, and contact soldering, Rehm Thermal Systems’ equipment ensures reliable, void-free solder joints — even when using flux-free solder pastes. Thanks to the integrated formic acid process, subsequent cleaning of the assemblies can be eliminated. This innovative technology was recognized with the Mexico Technology Award at the SMTA Guadalajara event.
Rehm Thermal Systems is responding to the industry’s growing demand to eliminate traditional fluxes and complex cleaning processes with an innovative and exclusive solution. By successfully integrating acid-based technology into the Condenso series, the company marks another technological milestone.
In the flux-free soldering process, the inert carrier gas (N₂) is enriched with formic acid (HCOOH) and introduced into the process chamber. The excellent heat transfer of the medium, combined with vacuum technology, ensures an optimal soldering process. Unlike traditional fluxes, which leave residues that must be removed, the formic acid completely decomposes into gaseous by-products (CO₂, CO, H₂O), enabling clean solder joints. This makes subsequent cleaning of assemblies unnecessary.
The Mexico Technology Awards 2025 were announced by the trade magazine Mexico EMS during a ceremony held at the Westin Hotel in Guadalajara, Jalisco. Forty-five companies were recognized for their contributions to the Mexican electronics industry. Once again, Rehm Thermal Systems Mexico received a Mexico Technology Award, joining the ranks of companies driving technological innovation, improving productivity and manufacturing quality, and delivering cost-efficient solutions. The CondensoXLine FA 2025 has also been nominated for the Productronica Innovation Award.
Rehm’s presence in Mexico is developing into an important hub for electronics manufacturing, particularly in consumer electronics and the automotive sector. The location recently celebrated its 10th anniversary and hosted a well-attended Technology Day. In its new 960 m² facilities in a modern industrial park in Guadalajara, Rehm supports both OEMs and EMS providers with locally adapted process technology.
