Why heavy copper PCB is different
Heavy copper PCB typically uses thicker copper to support high-current circuits, power conversion and thermal dissipation. However, thicker copper also changes etching behavior, trace spacing, solder mask coverage and lamination control.
Engineering teams should not treat heavy copper as a simple material option. It must be reviewed together with current load, heat path, component placement, creepage distance and PCB thickness.
Current carrying capacity and heat management
The copper weight, trace width and allowable temperature rise determine how much current a PCB can carry safely. Power boards, motor control products, LED lighting and industrial modules often require wider traces, thermal relief planning and stable copper distribution.
YourPCB reviews heavy copper requirements with manufacturing tolerance in mind, helping customers balance electrical performance, board size and production yield.
DFM items before RFQ
Important RFQ details include copper weight, minimum trace / spacing, finished thickness, solder mask bridge, surface finish, panel size and thermal requirements. Providing these items early allows the engineering team to review feasibility before tooling and production.
YourPCB value for heavy copper projects
YourPCB supports heavy copper PCB projects with engineering review, controlled PCB fabrication and optional SMT assembly integration. This helps customers reduce supplier coordination effort and keep PCB fabrication requirements aligned with the final assembly application.
RFQ preparation checklist
A clear RFQ package allows the engineering team to identify manufacturability risk earlier and respond with more accurate technical feedback. Before sending a request, prepare production data, target quantity, delivery expectations and quality requirements as completely as possible.
- Gerber / ODB++ data and fabrication drawing
- BOM, Pick & Place and assembly drawing when SMT is required
- Stack-up, impedance targets and material requirements
- Inspection, programming, ICT / FCT and packaging requirements
Why customers work with YourPCB
YourPCB combines engineering review, controlled PCB fabrication, SMT assembly, inspection, testing and responsive communication. The goal is not only to deliver boards, but to help customers reduce technical uncertainty before production and improve long-term manufacturing reliability.
