Exxelia Ohmcraft High voltage resistors in 3D dental imaging

To ensure the reliability of 3D imaging used by dentists, CBCT system manufacturers have relied on Exxelia Ohmcraft's custom high voltage resistors.


To capture adequate images of a patient’s teeth and jaw, dentists rely on advanced 3D imaging from cone-beam computed tomography (CBCT) systems. The CBCT system’s outputs are critical for the accurate diagnosis of oral health concerns and subsequent plans for treatment. To ensure the reliability of these images, manufacturers of CBCT systems have leveraged Exxelia Ohmcraft’s custom, high voltage resistors.

“In general, X-Rays require very high voltages to operate and generate clear, precise 3D images,” said Eric Van Wormer, Vice President of Exxelia Ohmcraft. “Because of the unmatched precision and control in surface-mount and leaded resistors from Exxelia Ohmcraft, manufacturers of this type of technology have turned to us to help ensure the reliability of their systems and the quality of the images they produce.”

CBCT systems are used to assist dentists in a variety of procedures, including dental implant placement, root canal therapy, the treatment of temporomandibular joint (TMJ) dysfunction, and oral surgery.

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 joins Heico Corporation group

The transaction will be carried out with IK Partners, majority shareholder of Exxelia since 2015, and should take place before the end of the first quarter of 2023.   Laurans A. Mendelson, HEICO's Chairman and Chief Executive Officer, along with Victor H. Mendelson, HEICO's Co-President and CEO of its Electronic Technologies Group, commented, "We are ecstatic that such a fine company, with its remarkable team members, management and products, will be part of HEICO, and we look forward to welcoming all of Exxelia's great people to the HEICO family. While furthering HEICO's strategy of expanding our already impressive range of mission-critical and Hi-Rel components for the most demanding applications, Exxelia also provides HEICO with added broad geographic and product diversity, including in the important European market."   Paul Maisonnier, CEO of Exxelia, commented, "We are excited to embark on a new stage of development with HEICO. We really appreciate the values of the Mendelson Family, which match perfectly those of Exxelia. Our goal to develop Exxelia into a world leader in Hi-Rel passive components and sub-systems for harsh environments, serving the aeronautic, defense, space and medical markets will be accelerated under the HEICO umbrella. Together we will strengthen our innovation and operational capabilities and accelerate our internationalisation strategy. We thank IK for their support over the past years, which has enabled us to establish a solid platform to support our ambitions for global growth."   Dan Soudry, Managing Partner at IK Partners and Advisor to the IK VII Fund, and Diki Korniloff, Partner at IK Partners, added: "As shareholders of Exxelia since 2015, we are very pleased to have been able to support its very talented management team through the various stages of transformation, structuring and growth of the Company, doubling its employee base to more than 2,100 people and leading to a strong increase in investment in R&D and in its manufacturing footprint. Notably, we believe that HEICO is an excellent home for Exxelia given that they share common values and we are very pleased HEICO is acquiring Exxelia. We'd like to take this opportunity to wish the team and HEICO all the very best for the future."     About HEICO Corporation HEICO Corporation is engaged primarily in the design, production, servicing and distribution of products and services to certain niche segments of the aviation, defense, space, medical, telecommunications and electronics industries through its Hollywood, Florida-based Flight Support Group and its Miami, Florida-based Electronic Technologies Group.
