FAQs
Can single sided metal core PCBs be routed or machined into complex shapes?
Yes, standard CNC routing and milling processes create complex board outlines, though tight radius corners require special tooling considerations due to the metal substrate's hardness compared to conventional PCB materials.
Can through-holes be drilled in single sided metal core boards?
Through-holes for mounting hardware can be drilled through the metal base, but these boards don't support plated through-holes for electrical connections since circuitry exists only on one side.
Can components be mounted on both sides of a single sided metal core board?
Components mount only on the circuit side since the metal base remains exposed for thermal contact with heatsinks or enclosures, though adhesive mounting occasionally secures low-profile components on the base side.
Are there special storage requirements for metal core PCBs before assembly?
Standard moisture-sensitive device precautions apply to surface finishes, though metal substrates resist moisture absorption better than organic materials, simplifying storage compared to conventional boards in humid environments.
How does metal core technology compare to heavy copper PCBs for thermal management?
Metal core boards provide superior heat spreading across the entire substrate compared to heavy copper's localized conductivity, making them more effective for distributed heat sources despite heavy copper's advantages for current-carrying capacity.
