Les Résistances d’Exxelia Ohmcraft permettent d’accélérer les tests de dépistage du COVID-19

Les entreprises de dispositifs médicaux et de diagnostique font appel à Exxelia Ohmcraft, leader dans la conception et la fabrication de résistances à couches épaisses, haute tension et haute précision, pour produire des résistances sur mesures répondant à des spécifications strictes.


En pleine pandémie mondiale du nouveau coronavirus (COVID-19), les experts ont déclaré qu’une pratique extensive de tests était essentielle pour endiguer la propagation du virus et renouer avec l’activité notamment dans les villes.

Les entreprises de dispositifs médicaux et de diagnostics ont travaillé sans relâche pour développer des solutions de test rapides et fiables. Pour rendre ces kits de test possibles, les fabricants se sont tournés vers Exxelia Ohmcraft, un leader dans la conception et la fabrication de résistances à couches épaisses, haute tension et haute précision.  

Les nouvelles solutions de test rapide impliquent le traitement des échantillons des patients à l'aide d'un thermocycleur, un instrument utilisé pour amplifier l'ADN et l'ARN afin d’identifier le COVID-19. Pour fonctionner, les thermocycleurs utilisent des résistances de montage en surface à haute valeur ohmique et à faible bruit d'Exxelia Ohmcraft. Ces résistances répondent à des spécifications strictes, notamment en terme d’encombrement pour permettre aux appareils de test d'être portatifs.  

«En raison de la crise actuelle, le client a fait en sorte que ces kits de test soient développés, produits et entre les mains du plus grand nombre d’acteurs du système de santé possible en un temps record. En tant que fabricant américain avec des délais de fabrication imbattable, Exxelia Ohmcraft a pu fournir des résistances sur mesures essentielles à leur mission », a déclaré Eric Van Wormer, Vice-Président d'Exxelia Ohmcraft.

«Nous sommes fiers de nous associer à des entreprises engagées dans la lutte contre COVID-19.» La technologie d'Exxelia Ohmcraft utilise le système d'impression électronique unique Micropen pour «imprimer» des lignes serpentines précises et étroites avec de l'encre résistive sur un substrat en céramique, produisant des résistances plus performantes sur une plage de valeurs plus large sur une surface plus petite que ce qui est possible avec une résistance à film de technologie conventionnelle.

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.

2023 Revolutionary Exxelia MML™ Ultra-High Energy Density Film Capacitors

Discover the power of MML™ technology The best performing film capacitors on the market with the highest energy density ever! Exxelia&#39;s revolutionary MML™ ultra-high energy density Film Capacitors are a game changer in the industry due to their unparalleled energy density of 400 J/dm3. This allows for a significant reduction in size and weight in comparison to traditional Polypropylene or Polyester dielectrics, as well as an increased operating temperature of up to 140°C and protection against transient voltage. Not only do MML™ capacitors offer a large flexibility in design, allowing for low profile configurations, but they have also been tested in actual cases for controls and DC-Links functions in aircraft applications and have shown a reduction in size and weight of about 50% compared to other film technologies.   Furthermore, when compared to MLCCs, MML™ capacitors have demonstrated a reduction in weight of between 70% to 90%, with no capacitance derating with voltage applied and a low drift of less than 5% across the temperature range. Applications that previously required clusters of stacked MLCCs can now be replaced by a single MML™ unit of similar size, with the added reliability that film dielectric offers. The exceptional properties of Exxelia&#39;s new MML™ capacitors make them suitable for a wide range of applications including power supplies, DC-links, AC/DC/AC power converters, charge/discharge or power generation functions of commercial/military aircraft, satellite platforms and payloads, launchers, defibrillators, downhole tools and any other applications that require confined electronics. Samples are available upon request.     Features & Benefits : Miniaturization of the function : Up to 50% size reduction vs other film technologies ; matching footprint with stacked MLCC Lightweight : 50% lighter vs other film technologies ; 80 to 90% lighter than ceramic No capacitance derating in voltage, stable in temperature (<5% drift through the temperature range) Capacitance from 1μF to 1000μF  Voltages from 50V to 1000V  Operating Temperature -55 °C to +140 °C Highly customizable   Get your white paper around our MML Film Capacitor Download our white paper now on our innovative Miniature Micro-Layer™ (MML™) technology, which offers the highest capacitance per volume for film capacitors available on the market, by filling out the form below.   Chargement&hellip;
