Glass PCB Fabrication Process
See how PCB designer process for making glass PCBs. They’re pretty much identical to regular, fiberglass-based PCBs, but building circuits on microscope slides. We’ve seen him build a glass PCB LED clock and a Linux Minecraft Ethernet thing, but until now, process of building these glass PCBs hasn’t been covered in the depth required to duplicate these projects.
Of course, building a glass PCB is useless without soldering components to it. For that, he is using bismuth solder paste for low-temp hot plate soldering. If you’re only doing single-sided SMD work, this is a great way to produce beautiful circuit boards made of glass, but now we’re wondering if a small enough diamond drill bit would allow for double-sided construction.
