Exxelia Ohmcraft Custom Resistors Help Ensure Speed and Accuracy of Automobile Electronics Testing

ROCHESTER, N.Y., July 28, 2020 — Before being sent off to dealerships for sale, automobiles are subject to a series of tests as part of the production process. To keep pace with industry trends and customer demands, today’s cars contain more electronic devices than ever, all of which must be tested ...


For this purpose, manufacturers of automotive testing systems have relied on Exxelia Ohmcraft—a leader in thick-film, high-voltage, high-precision resistor design and manufacturing—for more than 15 years.

This type of automotive testing ensures that all of the vehicle’s electronic components meet the most stringent testing standards, screening out any faulty devices or malfunctions. Tests are often run on multiple electronics simultaneously, increasing the complexity of these testing systems, which utilize precision low-noise chip resistors from Exxelia Ohmcraft for their accuracy and reliability.

“The automotive industry is rapidly changing and evolving, presenting manufacturers with not only new testing challenges, but the pressure to get their products into the market faster,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “By leveraging Exxelia Ohmcraft’s custom surface mount resistors, automotive testing manufacturers are able to help their customers—automobile companies—meet the demands of the industry.”

Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.

Exxelia Ohmcraft Custom Resistors Help Ensure Reliability of Most-Deployed Anti-Tank Missile in the World

In times of warfare, the reliability of military weapons is absolutely critical to the success of a mission. For nearly a decade, military contractors have leveraged Exxelia Ohmcraft’s custom, high voltage resistors and dividers to ensure product performance in a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world. In a variety of military applications, including the FGM-148 Javelin—the most-deployed anti-tank missile in the world.“Missiles are exposed to extreme climate conditions and often sit idle—sometimes for several years—before they are launched. When that time comes, it is essential for those missiles to perform as expected,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Exxelia Ohmcraft custom resistors are designed to support the rigorous precision and reliability specifications required by military suppliers to withstand the harsh environmental conditions, ensuring that the missile remains fully operational under all circumstances. Exxelia Ohmcraft performs a full range of military lot acceptance testing (LAT) on resistors as necessary, and works closely with military contractors to meet the design requirements for each particular application. In the case of the FGM-148 Javelin, a small, lightweight form factor was imperative to keep the missiles as lightweight and portable as possible. Exxelia Ohmcraft’s technology utilizes the proprietary Micropen electronic printing system to “print” precise, narrow, serpentine lines with resistive ink on a ceramic substrate, producing higher performance resistors over a wider range of values on a smaller surface area than is possible with conventional film resistor technology.
