New PCB substrates; While FR4, a glass-reinforced epoxy resin laminate, is a substrate of choice for PCBs due to being lightweight, strong, and cheap, it’s non-recyclable and can contain toxic ...
Product security and reliability are major concerns in the semiconductor and PCB fabrication industries. Because of this, ...

It says something for the status of FR4 as an everyday material that people notice when a printed circuit board (PCB) is not green. Yet both the fibreglass – yet another product of silicon – and the ...
