I once had a project where the client used a traditional adhesive laminate, causing the bonding layer to bubble during high-temperature testing and scrapping the entire batch \u2014 a lesson that applies just as much to a Cable Modem PCB. Switching to an adhesiveless 2-layer FPC structure cut thickness while improving temperature tolerance by roughly 20 degrees. Sputtering copper directly onto polyimide film costs more upfront, but it avoids adhesive breakdown at high temperatures, making it especially suited to automotive electronics and other high-temperature environments where a high-speed PCB manufacturer or general multilayer PCB manufacturer needs a reliable process."}
