Heavy Copper PCB
Engineering coordination for power PCB projects using heavy copper structures, increased current requirements, and project-specific thermal-management considerations.
MWX PCB reviews project requirements and coordinates feasibility, engineering feedback, inspection expectations, and production follow-up through the manufacturing route confirmed for the project.
Capability, materials, timing, inspection scope, and production resource are confirmed case by case after the actual files and requirements are reviewed.
HEAVY COPPER PCBTypical Applications
Application examples help frame the review; they are not a blanket capability or compliance commitment.
Capability Review
- Heavy copper structures reviewed by application
- Copper balance and etching review
- Thermal and current requirement communication
- Stack-up and finished-thickness coordination
- Selected copper-via and heat-transfer structures
Project-Specific Selection
- FR-4 material family selected by thermal and electrical needs
- Copper construction confirmed after current and stack-up review
- Thermal-management structures reviewed where relevant
- Final material and copper values require project confirmation
These are individual reference limits, not a promise that every limit can be combined in one design. Final feasibility depends on the complete Gerber data, stack-up, materials, quantity, quality scope, and production requirements and is confirmed through project-specific engineering review coordinated by MWX PCB.
Common Manufacturing Risks
- Etching compensation and conductor geometry
- Resin filling around heavy copper features
- Copper balance and board flatness
- Finished thickness and tolerance accumulation
- Thermal relief and solderability considerations
Inspection & Verification
- Copper-thickness evidence when specified
- Electrical test follow-up
- Cross-section review when required
- Final dimensional and visual inspection
Timing Confirmed After Review
Lead time is confirmed after copper construction, material, board thickness, tooling, and inspection requirements are reviewed.
MWX PCB coordinates the project and does not claim ownership of the production factory, equipment, certifications, or qualifications used for the build.
Heavy Copper PCB Project Questions
Is a maximum copper weight published as standard?
No. Heavy copper requirements are reviewed case by case because conductor geometry, finished thickness, and process route affect feasibility.
What information is needed for current-carrying review?
Provide copper requirements, conductor geometry, expected current, temperature constraints, stack-up, and applicable acceptance criteria.
Can heavy copper and fine features be combined?
This requires case-by-case engineering review because etching and registration requirements can conflict.
