Converters, battery-management systems, chargers and lighting require coordinated current, isolation and thermal design. Copper thickness or a metal core alone does not determine allowable current or temperature. Geometry, duty cycle, cooling and the complete assembly must be validated together.
Engineering Review Points
- Current paths: define continuous and transient currents, allowed temperature rise, copper per layer, trace geometry and terminal connections.
- Isolation: provide working voltages, creepage and clearance requirements, slots and dielectric withstand tests with environmental conditions and acceptance criteria.
- Thermal path: identify heat sources, dielectric requirements, cooling surfaces and mounting interfaces. For IMS, specify both isolation and thermal construction.
- Assembly: review large thermal masses, connector loads, solder access, coating and fixtures. Define functional-test records and responsibility for high-power test equipment.
Prepare Your Project Files
Send fabrication files, drill data, stack-up, copper requirements and mechanical drawings, with current, voltage and thermal conditions. For assembly, add BOM, placement and test procedures. Identify controlled materials, quantities and customer approval milestones before quotation.
