QPS

  • 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?

    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.

How unique alloy substance can help OEMs reduce the risk of ADAS-related recalls

 

A global automotive materials specialist has demonstrated the reliability benefits of a unique alloy substance that can replace traditional tin/silver/copper (SAC) alloys in the design of Advanced Driver Assistance Systems (ADAS). Internal tests suggest that this alternative alloy can play a significant role in helping automotive OEMs eliminate the risk of solder fractures, a potential cause of failure in ADAS hardware.

ESI Automotive held a series of quality tests to assess the reliability of Innolot alloys compared to conventional SAC and tin-silver (SnAg) alloys. The Innolot alloy was developed with the automotive industry for use in high temperature environments where vibration is also a factor. It is designed to offer significantly improved creep resistance, particularly when operating in temperature extremes such as within an ADAS circuit board assembly.

What did the quality tests prove?

“We ran a series of thermal cycling tests, pitting Innolot against the traditional SAC alloy. For this, we tested the alloy on two different ball grid arrays (BGAs), which are surface mount packages being used more in advanced safety designs,” explained Lenora Clark, Director of Autonomous Driving and Safety Technology at ESI Automotive.

“Our testing demonstrates that the size of the package, the pitch and the overall input and output does influence the characteristic life of the solder joint. Using both a 228 BGA and 256 BGA, the Innolot alloy improved solder joint reliability by a defined percentage when compared to the traditional SAC alloy. The percentile difference was 39% for the 228 BGA and 16.3% for the 256 BGA. This is a significant difference in reliability.”

“Our results conclude that the creep resistance properties of the Innolot alloy offer significant improvements in reliability over standard SAC.”

Lenora added: “This is significant when you consider the context of carmakers progressing vehicle designs towards level three autonomy. Traditional solder alloys are still commonplace within ADAS hardware designs but as we move vehicle systems towards level three autonomy, we need to consider alternative options.

“People don’t always think about ADAS operating in harsh environments. These systems are doing a high volume of processing and therefore generate their own heat as part of this function. In addition, because these systems are safety-critical, carmakers need to ensure they are reliable enough to withstand up to 3,000 thermal cycles. This cycle of constant heating and cooling is too extreme for traditional solder to withstand in new vehicle designs, necessitating the need for a high reliability alloy such as Innolot, to reduce the risk of ADAS failure and associated warranty and recall situations.
