Searching for a Rogers PCB manufacturer in China is not as straightforward as it may seem. Many suppliers use “Rogers PCB” as a search term, but that does not necessarily mean they have meaningful experience with RF stackups, PTFE or hydrocarbon-ceramic laminates, bondply selection, controlled impedance, plasma treatment, or material traceability. These details matter because […]
