|PowerRibbon™ Bonding - An Alternative Interconnect Process for Present & Future Automotive Electronics Applications|
|Keywords: wire bonding, PowerRibbon™, interconnect|
|Large wire bonding is used in automotive electronics packaging since the mid-1970s. It is used as the interconnect of choice between the module housing as well as the power device and the electronic substrate. Large wire bonding is also the most commonly used interconnect for industrial power modules. It’s flexibility paired with benefits of being an environmentally friendly and robust process performed at room temperature made it the perfect interconnect choice for these complex applications with high reliability requirements. Electronic power steering and hybrid drives are only two of many examples in modern automotive applications which need increasingly higher current capabilities, requiring high power module packaging technology. To address these applications, manufacturers have historically increased the number of large aluminum wires per device or moved to alternative technologies. This posted a growing challenge for large wire bonding. Even though well established and accepted, in both areas, industrial and automotive power modules, the ever larger numbers of wires to be bonded virtually defect-free in a high volume environment under significant cost common for automotive applications, required a fresh review of the interconnect process and the equipment used. Where multiple wires only impact productivity, alternate technologies are less flexible or less reliable than wire bonding and can require extensive re-qualification efforts and investments in new capital equipment. Orthodyne's new PowerRibbon™ Technology was developed to meet the current and future interconnect needs of the power module market. PowerRibbon™ is a new technology designed to work in existing aluminum wire bonding applications, as well as new designs specified for PowerRibbonTM bonding. It requires little change in many of today's existing designs and utilizes the same environmentally friendly room temperature ultrasonic process as aluminum wire bonding. PowerRibbon™ combines the flexibility and robustness of the large aluminum wire bonding process with a higher productivity and in many applications an improved product performance. This paper will discuss wire and ribbon bonding design and performance aspects in present and future automotive applications.|
