Heavy Copper PCB
Circuit boards for power electronics and high-current paths that need thicker copper.
Heavy Copper PCB with ShinePCB
Heavy copper boards carry more current and spread heat more effectively. Copper weight, trace geometry, spacing and thermal needs are reviewed together, and the parameters are confirmed for each project before quotation.
- Copper weight by layer
- Trace width and spacing for current
- Thermal paths and via arrays
- Mixed copper weights on one board

Typical applications
Power supplies and converters
Motor drives and battery systems
Industrial power distribution
From prototype to production
Every order follows the same controlled sequence. Prototype and production requirements are reviewed separately.
File review
Gerber or ODB++, drill data, drawing and quantities are checked for completeness.
Engineering questions
Open points on manufacturability, materials or special processes are sent before quotation.
Stack-up and material
Construction, laminate and finish are confirmed with you and written into the order.
Fabrication
The order is released to the facility whose process and qualification fit the requirements.
Inspection and test
Inspection and electrical test follow the methods agreed for your order.
Packing and delivery
Boards are packed and shipped under the confirmed delivery terms.
What to send for a PCB review
Start with the details you have — engineering will request anything else needed for the review.
Files and details for a PCB review
- Gerber (RS-274X) or ODB++ data with drill files
- Fabrication drawing with material, thickness and finish
- Stack-up and impedance targets, if any
- Quantity for prototype and for production
- Special requirements such as IPC class, testing or packaging
Technical files stay private
Customer Gerber, BOM and design data are managed under an ISO/IEC 27001 information security system and shared only within your project.
Heavy Copper PCB FAQs
What copper weight can you build?
Copper weight depends on the full design and is confirmed in engineering review for each project.
Can heavy and standard copper be combined?
Mixed copper constructions are reviewed per design.
