Exxelia诞生于五家历史悠久的公司的合并，这些公司具有互补的专业知识（Eurofarad，Firadec，Sic Safco，Microspire等），后来加入了Temex，Dearborn，N'Ergy，Raf Tabtronics，DeYoung和Micropen。 Exxelia是复杂无源组件和创新子系统的制造商，这些子系统旨在承受恶劣的环境。 Exxelia的产品（电容器，滤波器，电阻器，滑环，磁性元件，精密机械零件和特殊传感器）主要用于电力电子，能量产生和存储，滤波和信号处理。 Exxelia在先进的工业市场中运营，例如国防，太空，航空，能源，运输，医疗和电信。

Exxelia能够满足复杂的技术规格，并能够通过最苛刻的资格认证程序（MIL，QPL等）来设计标准和定制产品，从而获得认可。

Exxelia在全球约有2,000名员工，分布在4个国家（法国，美国，摩洛哥，越南）的14个地点。

Ohmcraft成立于1982年，迅速成为厚膜，高电压，高精度电阻器设计和制造领域的领导者。我们的技术使设计工程师能够设计专用电阻器，以满足我们合作和驱动合作伙伴的需求。

Ohmcraft成立于1982年，迅速成为厚膜，高电压，高精度电阻器设计和制造领域的领导者。高压电阻器和高值电阻器方面的专业知识使我们的设计工程师能够达到并超过最具挑战性的产品规格。我们的技术使工程师能够设计专用电阻器，以满足我们合作伙伴的需求。 Micropen技术在我们所有的表面贴装电阻器，含铅电阻器，分压器和网络中都具有相同的卓越技术性能。我们能够在三维承印物上进行打印，从而能够真正定制每个我们致力于的项目。 Ohmcraft电阻器在高压，高精度，TCR和TCR跟踪，VCR和VCR跟踪，低噪声，稳定性和耐脉冲性方面提供行业领先的性能。

如今，Micropen电子打印系统已成为设计和制造Exxelia Ohmcraft完整电阻器系列的核心技术-片式电阻器，扁平引线电阻器，轴向引线电阻器和定制电阻产品解决方案。此外，姊妹部门Exxelia Micropen利用Micropen电子打印系统来设计，开发和制造一些世界上最具创新性的电子设备。

在Ohmcraft，我们将材料科学+设计工程+印刷电子技术集成在一起，其结果就是Micropen技术–通常称为Micropenning®，该专有技术用于设计和制造业内最精确，最稳定的电阻器。

Micropenning是一种“直接写入”技术，是Ohmcraft制造其电阻器系列的专有技术。与其他印刷技术相比，这项专有技术可以沉积具有更高保真度，准确性，可重复性和厚度控制的厚膜电阻器材料。

与丝网印刷相比，“微喷”工艺可以印刷宽度仅为几密耳的线条，边缘更平滑，厚度精度更高。这为设计工程师提供了无与伦比的功能和设计选项–长而窄的走线（无颈缩）允许在较小的封装中使用更长的图案。使用电阻率较低的油墨与高宽比设计结合使用的Ohmcraft电阻器可以显着改善电气性能。这允许等效的电阻器以更高的电压和/或更高的电阻在更小的封装中生产。

Exxelia was born from the merger of five long-established companies with complementary know-how (Eurofarad, Firadec, Sic Safco, Microspire et Astema) later joined by Temex, Dearborn, N’Ergy, Raf Tabtronics, DeYoung and Micropen. Exxelia is a manufacturer of complex passive components and innovative subsystems, designed to withstand severe environments. Exxelia’s products (capacitors, filters, resistors, slip rings, magnetic components, precision mechanical parts and special sensors) are mainly used in power electronics, energy generation and storage, filtering and signal processing. Exxelia operates in advanced industrial markets such as defense, space, aviation, energy, transportation, medical and telecommunications.

Exxelia is recognized for its ability to meet complex technical specifications and to design standard and custom products passing the most demanding qualification procedures: MIL, QPL, etc.

Exxelia employs around 2,000 employees worldwide spread into 14 sites in 4 countries (France, United States, Morocco, Vietnam).

Established in 1982, Ohmcraft quickly became the leader in thick film, high voltage, high precision resistor design and manufacturing. Our technology allows design engineers to design application-specific resistors to fit the needs of our collaborative and driven partners.

Established in 1982, Ohmcraft quickly became the leader in thick film, high voltage, high precision resistor design and manufacturing. Expertise in high voltage resistors and high value resistors has enabled our design engineers to meet and exceed the most challenging product specifications. Our technology allows engineers to design application-specific resistors to fit the needs of our collaborative partners. Micropen technology has the same superior technical performance in all of our surface mount resistors, leaded resistors, dividers and networks. Our ability to print on three dimensional substrates allows us to truly customize each project we commit to. Ohmcraft resistors provide industry-leading performance in high voltage, precision, TCR and TCR tracking, VCR and VCR tracking, low noise, stability and pulse-withstanding capability.

Today, the Micropen electronic printing system is the core technology for the design and manufacture of Exxelia Ohmcraft’s complete line of resistors – chip resistors, flat leaded resistors, axial leaded resistors and custom resistive product solutions. In addition, Exxelia Micropen, the sister division, utilizes the Micropen electronic printing system to design, develop and manufacture some of the world’s most innovative electronic devices.

At Ohmcraft, we integrate material science + design engineering + printed electronics and the result is Micropen technology – commonly referred to as Micropenning®, this proprietary technology is utilized to design and manufacture the most precise and stable resistors in the industry. 

Micropenning, a “direct write” technology, is Ohmcraft’s proprietary technique for manufacturing its family of resistors. This proprietary technique allows for the deposition of thick film resistor material with higher fidelity, accuracy, repeatability, and thickness control than can be achieved by other printing techniques.

The “Micropenning” process can print lines down to a few mils in width with smoother edges and greater thickness accuracy than screen printing. This provides design engineers with unmatched capability and design options – long, narrow traces without neck downs allow for longer pattern lengths in smaller packages. Ohmcraft resistors made using lower resistivity ink in combination with a higher aspect ratio design can significantly improve electrical performance. This allows for equivalent resistors to be produced in smaller packages with higher voltages and/or higher resistances.
