  • Meeting directives, such as ELV REACh and RoHS continues to be essential requirements. QPS delivers on all of these needs. QPS complies with the conditions set forth in the ISO 9001: 2015.


    QPS helps automotive engineers to specify the right products in a sustainable world. The steady evolution of the program has enabled many global OEM’s to specify ever-higher performance standards and represents:

    • Approved applicators: Applying these products to a common audited standard ensures the same coating performance throughout the applicator base.
    • High performance: Exceeding the high demands for corrosion resistance and exceptionally consistent torque and tension characteristics.
    • Global consistency: Wherever ZinKlad, DecoKlad or XMAPP standards are applied, applicators know they are using the same high-performance products.

    What do we do?

    QPS flow chart

    We supply and develop QPS standards that meet and exceed OEM specifications. We validate applicators processes by conducting audits, carrying out inspections and testing the production output to make sure they meet pre-defined QPS standards and agreed technical requirements.

    We monitor and report results on a global scale to be able to service and continuously improve performance. 

    Why do we do what we do?

    We believe that we are able to assure a global consistent performance at a local level meeting the global OEM requirements with a select number of world class applicators.

    How do we do what we do?

    ESI Automotive has developed a unique Quality Performance System called QPS that tackles the challenges for high-performance automotive coatings. OEM’s can be confident that the same coatings and consistent performance are available worldwide.

ESI Automotive to exhibit at Electric & Hybrid Vehicle Technology Expo Europe

ESI Automotive shows how to improve EV reliability more than tenfold

Electric vehicle materials specialist ESI Automotive will present sintering technology that can improve inverter reliability more than tenfold at the Electric & Hybrid Vehicle Technology Expo Europe in Stuttgart between June 28-30. The result for automakers is more reliable electric vehicle powertrain systems which benefit from increased range and improved efficiency.

From Hall 10, Booth A96 at Messe Stuttgart, ESI Automotive will demonstrate the value of moving from a conventional module design within vehicle inverters, to a fully sintered module. Whereas a conventional module uses wire bonding and soldering technology, a fully sintered module instead utilizes clips and sinter technology.

Since the sintering process is based on atomic diffusion, this means a sintered bond can be formed within the power module to attach dies, packages and top sides, resulting in a higher melting point than traditional solder. The melting point of silver is 962°C, while the melting point of typical solder alloys varies between 220°C to 280°C. For automakers, the result is a more reliable inverter with greater thermal and electrical conductivity and a longer operating lifecycle.




Furthermore, ESI Automotive has proven in several tests that opting for sintering technology over traditional solder for power module development within inverters, significantly increases the durability of alloys. For example, the company’s ALPHA® Argomax® sintered silver technology has been proven to improve EV efficiency by 40% compared to traditional solder and tin copper alloys. This, in addition to achieving a potential 75% reduction in die count and a 34% reduction in inverter weight, enables OEMs to design drivetrains with greater range and lighter weight, thereby further improving vehicle efficiency.

Critically, ALPHA® Argomax® has also been proven by ESI Automotive to have a lower failure rate than traditional solder. Internal tests showed that solder fails after 12,000 cycles, whereas full sintered technology is still fully operational after 150,000 power cycles, representing a more than tenfold reliability increase. Even at testing temperatures of up to 170°C, sintered silver is still functional after 350,000 power cycles.


“With major vehicle manufacturers all facing the same challenge to improve electric vehicle range and reliability, it is not surprising that many are looking towards new materials for higher efficiency levels.

“Results from some of the tests we have carried out on ALPHA® Argomax® demonstrate some of the milestones OEMs can achieve when they replace traditional solder with sintered silver. Not only can power density and reliability be increased, but silver sintering can also have a positive light-weighting effect, which drives further vehicle efficiency improvements.

“We are looking forward to showcasing this technology to supply chain partners at the Electric & Hybrid Vehicle Technology Expo in Stuttgart later this month.”
