中文摘要：
提出了一种在电力电子集成模块内使用的簧片压接互连工艺，该工艺具有很高的长期可靠性，核心是使用铍青铜制作的弹簧，该弹簧不仅提供足够的压接力，同时还实现可靠的电气连接。压接工艺具有十分优良的抵抗热应力的能力，并且工艺流程也很简单。研究了压接工艺的电接触特性。基于该工艺研制了一个4kW的半桥集成模块，并通过温度循环实验和功率考核实验证明了工艺的可行性。
英文摘要：
This paper presents a novel pressure contact interconnect technique in integrated power electronic module （IPEM） with high reliability. The central component of this technique is a break spring made of BeCu alloy. The break spring not only provides enough press-contact force, but also implements electrical interconnection. The technique exhibits excellent ability of withstanding thermal stress, and is also manufactured with a very simple process. Contact resistance of the pressure contact structure is investigated. A half-bridge IPEM based on pressure contact technique is proposed. Thermal cycling and power experiments were carried out, and the break spring pressure contact technique is verified to be feasible.
