Glass PCBs are circuit boards that have a glass base as their main material. Unlike conventional PCBs, glass circuits don\u2019t use resin substrates or FR-4. Glass offers both mechanical strength and thermal stability, making it the good option for PCB.<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
