Recyclable PCB created by the University of Washington is made from Vitrimers

Vitrimer Based Recyclable PCB

Ludwik Leibler a Polish-born French physicist and his team from the Laboratoire Matière Molle et Chimie at ESPCI ParisTech created a new class of plastics known as “vitrimers” and material researchers at the University of Washington (UW) have leveraged the new plastics to develop a recyclable PCB (printed circuit board) known as “Vitrimers PCB” (vPCB) that can be recycled many times over. The team tested their vPCB for strength and electrical properties and found that they are very similar to standard FR-4 PCB material. This means Vitrimers PCBs could offer a solution to reduce landfill waste and make it easier to recycle leftover copper, maximizing resource recovery. Key Features of Vitrimers-based Recyclable PCBs: Base material – Employs vitrimer epoxy, a type of polymer that can be repeatedly cured and uncured without damage. Environmentally sustainable – Designed to reduce e-waste and offer a more circular lifecycle for electronics. Performance – Electrical […]

Why Use Gold Rather Than Silver And Copper in PCB Fabrication?

pcb manufacturing copper vs gold

Needless to say, PCB is the support body of electronic components and the carrier of electrical connection of electronic components, which mainly plays the role of support and interconnection. Now printed circuit board (PCB) is widely used in various electronic and related products. There are three main colors on the external layer, such as gold, silver, and light red. They are classified by price: gold is the highest price, silver is second, and light red is the cheapest. But there is mainly pure copper that is bare copper in the internal of printed circuit board. Why are there precious metals on the PCB? Why are there precious metals on the PCB? PCB as a support for electronic components, its surface needs to be soldering components, so there is a part of copper layer requiring to be exposed for soldering. These exposed layers of copper are called pads, which are usually […]
