应对大功率电子产品制造中的挑战

电力电子是一个快速发展的领域,其驱动力来自技术进步、对能源效率需求的增长以及向可再生能源的转型。

通过先进的表面处理确保可靠性和使用寿命

在高功率电子领域,微型化和更高性能的追求带来了一系列复杂的挑战。确保多种材料的无缝集成对于管理超过1000A电流的电力电子设备的可靠性和寿命至关重要。金属表面的缺陷(如空隙和氧化)可能会严重损害这些组件的性能和安全性。

Plasmatreat的Openair-Plasma®清洁和活化技术,以及创新的REDOX®-Tool,提供了先进的解决方案,有效应对这些关键挑战。通过确保洁净、无氧化的表面,这些创新技术增强了附着力、电气性能和整体可靠性,为生产下一代高性能电子设备铺平了道路。

Extreme demands on materials and connections

半导体与功率模块生产中的挑战

材料与互连技术的严苛要求

高性能功率模块必须在极端环境下持续稳定工作数年。无论是电动汽车、风力发电机还是工业驱动设备,这些组件都面临着高温、高压和强机械应力的多重考验 —— 且设计空间日趋紧凑。

真正的挑战在于所谓的"三相点"区域:铜、陶瓷和灌封材料等多种材料的交界处。这些区域易出现应力集中、气泡残留或粘接失效等问题,都将显著缩短模块使用寿命。根本原因之一在于金属表面氧化导致的焊接性下降和接触电阻增加。此外,注塑包封过程中的环氧树脂分层也是常见风险。要解决这些问题,可靠的互连技术和精准的表面处理至关重要。

 

Our solution for typical power pain points

  • The REDOX® -Tool ensures the effective, inline removal of oxide layers on metal surfaces—especially on large lead frames and power modules.
  • We treat the surface with Openair-Plasma® before sintering, soldering, or encapsulation steps to guarantee maximum adhesion and perfect connections.
  • PlasmaPlus® provides a targeted nano-barrier coating that prevents moisture, ion migration, and premature aging.
  • Continuous inline processing guarantees consistent process monitoring, the highest quality, and maximum output rates—even with very demanding designs.

Comparison with competitive processes—Why Plasmatreat is superior

Other cleaning processes such as wet chemistry, vacuum procedures, or mechanical methods face key limitations. Wet chemical cleaning removes thick oxide layers but needs chemicals, complex rinsing steps, and causes environmental pollution. Vacuum processes are mostly batch operations, use a lot of energy, and are difficult to automate. Mechanical techniques like brushing risk leaving particles and aren't reliable for inline quality.

Plasmatreat sets new standards: Openair-Plasma® and REDOX® tools deliver fully automated, physical, chemical-free cleaning in-line that outperforms conventional processes. These methods reliably remove even tough oxide layers, prepare large or complex parts, and, with PlasmaPlus®, form a protective nano-barrier against moisture, migration, and aging. 

Plasmatreat offers maximum process integration, scalability, and sustainability—without compromise.

环保和成本效益

通过最大限度地减少对化学助焊剂和清洁剂的依赖,Plasmatreat解决方案可减少制造过程对环境的影响。工艺效率的提高、产量的增加和耗材用量的减少都有助于降本增效。

Industry-specific practical scenarios

E-mobility

Secure bonding, consistent performance even under continuous load

Renewable Energy

Photovoltaic and wind energy systems require long-term durability despite exposure to UV radiation, moisture, and temperature swings. Plasma coatings help protect critical contact areas and improve reliability.

Industrial Automation

Power modules in industrial and robotic systems must withstand vibration, dust, and harsh media. Plasma treatment improves adhesion of potting compounds and ensures long-lasting, high-integrity connections.

Our solution: Precise surface treatment for reliable power modules

Plasmatreat’s Openair-Plasma® technology and the REDOX®-Tool provide advanced inline cleaning and oxide reduction that ensure optimal adhesion and reliable performance—even for demanding applications. 

Oxide layers and weak adhesion are thoroughly eliminated, resulting in clean, defect-free surfaces.This leads to improved conductivity for power modules and semiconductors, higher yield rates, and less rework due to consistently clean processes. Durable adhesion and material compatibility maximize product reliability and service life, especially under tough conditions.

With Plasmatreat, manufacturers can count on best-in-class results for next-generation high-performance electronics—delivering superior electrical properties and long-lasting quality.
