Infineon launches biodegradable PCB substrate

【Lansheng Technology Information】According to statistics from the World Economic Forum, more than 54 million tons of waste electronic equipment are generated globally every year, and the electronic waste generated by these waste equipment is growing at a rate of 2.5 million tons per year, but only 17.4% of Collect and recycle. Circuit boards have little value after being cut, so they are often disposed of as waste, landfilled, incinerated, or piled up. This not only causes a waste of resources, but also pollutes the environment.

In order to solve this problem, Infineon, Germany's largest semiconductor manufacturer, and Jiva Materials, a British start-up company, recently launched Soluboard, a recyclable and degradable PCB substrate composed of natural fibers and halogens.

Infineon considers full-scale adoption of Soluboard in the future
"The first use of recyclable, biodegradable PCB materials in electronics design for consumer and industrial applications is a milestone towards a green future," said Andreas Kopp, Head of Product Management Discrete Devices, Green Industrial Power Division, Infineon. There is also active research into the end-of-life reusability of discrete power devices, which will be another important step in driving a circular economy in the electronics industry."

Infineon said it is using biodegradable materials to reduce the carbon footprint of demonstration and evaluation boards, and is also exploring the possibility of using the material in all circuit boards to make the electronics industry more sustainable.

Infineon has currently produced three different demonstration boards using Soluboard and plans to expand its product range in the coming years. It has already been deployed in more than 500 devices, showcasing the company's portfolio of power discretes, including a circuit board with components designed for refrigerator applications. Based on the results of ongoing stress tests, Infineon plans to provide guidance for the reuse and recycling of power semiconductors removed from the Soluboard, which can significantly extend the service life of electronic components.
