Benchuang provides custom insulated metal base PCB services and is a professional insulated metal base PCB manufacturer in China. Our Insulated Metal Base PCBs (IMPCBs) excel in thermal management with high thermal conductivity (1-3 W/mK or higher in copper variants), dissipating heat efficiently from high-power components while maintaining lightweight aluminum or copper substrates and dielectric insulation layers for electrical isolation. We support 1-4 layers with precise trace widths down to 0.1mm (4 mil), impedance control (±10% tolerance), and robust surface finishes like ENIG, OSP, or HASL to ensure vibration resistance (up to 10G), corrosion protection, and reliability in demanding conditions without bulky heat sinks.
