Perfect Surface Treatment Processes for Reliable Power Electronics
Plasma-based surface treatment for power electronics - meet Plasmatreat at PCIM in Nuremberg
Power electronics form the foundation of modern power converters, e-mobility, and industrial applications. Reliable material bonds throughout the entire process are indispensable due to high power densities and increasing miniaturization. Oxides, voids, delamination, and material incompatibilities pose significant risks to quality and reliability.

In power module manufacturing, long-term reliability depends on perfectly prepared surfaces at every step of the process. Plasma technology enables precise surface preparation by removing oxides and residual contaminants while cleaning and activating materials for subsequent processes, such as coating, molding, bonding or applying thermal interface materials (TIM). The result is improved adhesion, reduced risk of delamination, and consistently stable interfaces—all of which are essential prerequisites for robust, high-performance power modules.
Plasma treatment also supports reproducible, inline-capable processes and helps manufacturers meet the growing demand for miniaturization, power density, and thermal performance.
Plasmatreat's atmospheric pressure, Openair-Plasma® and vacuum plasma, AURORA-Plasma ,technologies cover the entire range of solutions, including the removal of oxides and flux, improving adhesion, preventing EMC delamination, and optimizing surface preparation for TIMs.

Extreme demands on materials and connections
High-performance power modules must deliver reliable operation for years under extreme conditions—in electric vehicles, wind turbines, or industrial drives. High temperatures, voltages, and mechanical stresses coincide with increasingly compact designs. A major challenge arises at so-called “triple points,” where materials like copper, ceramics, and potting compounds meet. These zones are prone to stress, voids, and adhesion issues that can drastically reduce service life. Oxidized metal surfaces further impair solderability and raise contact resistance, while overmolding increases the risk of epoxy delamination.
The solution lies in reliable interconnect technologies and precise surface treatment to ensure long-term stability.
Comparison with competitive processes—Why Plasmatreat is superior
Other cleaning processes such as wet chemistry, vacuum procedures, or mechanical methods face key limitations. Wet chemical cleaning removes thick oxide layers but needs chemicals, complex rinsing steps, and causes environmental pollution. Vacuum processes are mostly batch operations, use a lot of energy, and are difficult to automate. Mechanical techniques like brushing risk leaving particles and aren't reliable for inline quality.
Plasmatreat sets new standards: Openair-Plasma® and REDOX® tools deliver fully automated, physical, chemical-free cleaning in-line that outperforms conventional processes. These methods reliably remove even tough oxide layers, prepare large or complex parts, and, with PlasmaPlus®, form a protective nano-barrier against moisture, migration, and aging.
Plasmatreat offers maximum process integration, scalability, and sustainability—without compromise.
Our solution: Precise surface treatment for reliable power modules
Plasmatreat’s Openair-Plasma® technology and the REDOX®-Tool provide advanced inline cleaning and oxide reduction that ensure optimal adhesion and reliable performance—even for demanding applications.
Oxide layers and weak adhesion are thoroughly eliminated, resulting in clean, defect-free surfaces.This leads to improved conductivity for power modules and semiconductors, higher yield rates, and less rework due to consistently clean processes. Durable adhesion and material compatibility maximize product reliability and service life, especially under tough conditions. With Plasmatreat, manufacturers can count on best-in-class results for next-generation high-performance electronics—delivering superior electrical properties and long-lasting quality.
