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?Image
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.
Advances in sintering technology are key to improved inverter designs, providing OEMs with a raft of benefits
ESI Automotive offers a range of products and solutions suited to the electric vehicle industry. On the one hand, the Connecticut, USA-headquartered company provides what it refers to as industrial solutions – including processes for working with lightweight materials such as aluminum and magnesium. Secondly, the company’s electronics division provides solutions for assembly and circuitry.
“It’s a combination which makes us unique,” explains Chris Klok, director of vehicle electrification technology at ESI Automotive. “We have product solutions for producing semiconductors, circuit boards, connectors, and all sorts of materials to assemble these.”
While ESI Automotive’s product and process offering remains applicable to ICE vehicles – on what Klok refers to as the signal side, with PCBs and electronics controlling, for example, the fuel and air inlet – the company’s assembly, materials, and semiconductor expertise is of particular relevance in inverter design for electric and hybrid vehicles. The design and efficiency of the inverter is vital, Klok explains, not least because of the importance of EV/hybrid powertrains in differentiating make and model performance.
“The inverter and the electric motor determine the performance and the comfort of the car,” he says. “This used to be the role of the IC engine. Other components would very often be outsourced, but the engine was almost always the OEM’s core technology. Now, all of a sudden, this role is fulfilled by the electronics.
“If [competing] vehicle manufacturers used the same inverter and electric motor, it will seem that there’s no longer any competitive advantage.”
This has led to vehicle OEMs taking on a more active role in development and production of their own electronic systems.
“You’ll see these manufacturers produce more of their own electronics,” Klok continues. “For example, you can go online and see films of various OEM factories where they are building their own electric motors, battery electronics and associated components. It’s a completely new world, and a very interesting one for us.”
Inverters are made up of power semiconductors which were usually soldered. ESI Automotive developed a solution, more than a decade ago, which uses silver sintering technology.
“This improves the current passthrough, hence the conductivity, by almost 40%,” Klok explains. “You can understand why this continues to attract the interest of electric vehicle manufacturers.”
The development is the latest in a series of advancements that ESI Automotive has made in recent years.
“If you look at electronics materials history, there are only a few examples of a revolution,” Klok says. “One example is when the semiconductor industry moved to using plating technology to cope with the needs for miniaturization. Another was the move to lead-free soldering, when we had to design new solder alloys. I believe going from soldering to sintering for power semiconductors is also a revolution.”
There are a number of OEM partner which shared ESI Automotive’s belief in this new technology, as Klok explains.
“I can give you an example of a supplier chain partner which used to have an inverter type that was soldered. The semiconductor devices were soldered to the substrate, and they needed over 90 of them. They updated this inverter using our sintering technology and managed to reduce the semiconductor content by 75%. That decrease meant a reduction not just in weight, but also in dimension and cost. They changed other parts as well, but the main change was going from soldering to sintering.”
