Power module packaging: latest innovations are driven by EV/HEV and WBG technologies

Extracted from: Power Module Packaging 2018: Material Market & Technology Trends report, Yole Développement – Automotive Power Module Packaging Comparison report, System Plus Consulting – Release date: July 2018.

Technical innovations in power module packaging are mainly driven by the challenging system requirements of the booming EV/HEV(1) industry and the entrance of WBG(2) materials.
The companies Yole Développement (Yole) and System Plus consulting, both part of Yole Group of Companies propose today, two dedicated analyses to get a better understanding of the market evolution and technical issues of the power module packaging industry: Power Module Packaging Report, 2018 edition and Automotive Power Module Packaging Comparison 2018 report.

Once again, both partners combine their expertise to provide a deep added-value study. Taking into account the whole value chain, the market issues and technical expectations, analysts propose you today a valuable vision of the tomorrow’s industry.

The introduction of the WBG semiconductors, SiC(3) and GaN(4) is today pushing the development of new power packaging solutions, announces the market research and strategy consulting company, Yole. SiC technologies become step by step an essential solution to answer the industrial requirements, with a market estimation reaching 29% CAGR(5) between 2017 and 2023(6). Actually, WBG devices can work at higher switching frequencies and higher junction temperatures.
The latest Model3 inverter from Tesla is a good example of WBG penetration, showing the added-value of STMicroelectronics’ SiC power module, reverse engineered by System Plus Consulting (More info.).

Beyond the semiconductor industry, the EV/HEV industry’s demand for high power density and mechatronics integration is also driving many power electronics innovations with dedicated packaging solutions. New standards in terms of electrical devices and systems become a reality, pushing electronic components to work in non-conventional environments for longer. System Plus Consulting’s report, Automotive Power Module Packaging Comparison 2018 report details the physical composition and cost of ten modules for automotive applications from five different manufacturers. Analysts reviewed the different topologies and techniques used for the module packaging. Under this new report, System Plus Consulting’s analysts highlight the specificities of each solution, defined by the car makers.

“There is not yet a standardized package in automotive application” comments Farid Hamrani, Cost Engineer at System Plus Consulting.

Under a continuous process of innovations, the power module packaging industry is in a good shape. This market is showing a 8.2% CAGR during the period 2017-2023, reaching a global sector of almost US$ 2 billion at the end of the period.
With two major technical trends, over-molded double-side cooled modules for hybrid cars and single-side cooled modules with pin-fin baseplates for full electric cars, this industry is dominated by IGBT power modules: “The IGBT power module market grew 18.1% in 2017”, announces Dr. Milan Rosina, Senior Technology & Market Analyst, Power Electronics & Batteries at Yole. “No doubt today, that IGBT modules are driving the power module packaging materials business.
Consequently the overall power module market is expected to be over US$5.5 billion in 2023. This promising market is directly beneficial for the packaging material business. The power module packaging material business is worth US$1.2 billion, a little more than a third of the total power module market.
It is a very dynamic market, where continuous innovations and material enhancements and a lot of R&D investment are needed”, comments Alejandra Fuentes Suarez, Technology & Market Analyst at Yole.
This power module packaging material market’s CAGR for 2017-2023 will be 8.2%, coming close to a US$2 billion business opportunity by 2023….
