Custom Metal-Core PCBs for LED & Power Electronics

A metal base helps spread heat, but the complete assembly must still transfer that heat to its surroundings. Whether a separate heat sink or thermal interface is needed depends on the heat load, mounting arrangement, airflow, and allowable component temperature. Define the intended cooling method and validate the assembled product under its actual operating conditions.

Compare the thermal requirements with the allowable board weight, mechanical features, and project cost. The metal base is one part of the complete heat path, so include the dielectric, component thermal connection, and heat-sink interface in the review. XinshunPCB can discuss suitable construction options when you provide the component layout, operating conditions, and cooling arrangement.

Provide Gerber or ODB++ files, drill data, the board outline, fabrication notes, order quantities, and your requested schedule. Include the preferred metal base, board thickness, circuit copper, surface finish, and any dielectric requirements. Identify heat-producing components, mounting features, electrical isolation requirements, and requested tests. For assembly, also send the BOM, placement files, and assembly drawings.

Identify the required separation between the circuit and metal base, the operating voltage, and any agreed dielectric test conditions. Show mounting-hole sizes, locations, countersinks, keep-out areas, and which surfaces contact the enclosure or heat sink. State any direct thermal-pad requirements separately. Review these details before production so electrical isolation and mechanical fit can be checked together.

Consider a metal-core PCB when heat from LEDs or power components is an important part of your design. Review the component layout, available cooling space, electrical insulation, board mounting, and connection to the heat sink together. Share these requirements with XinshunPCB so the proposed board construction can be assessed against the needs of your product.
