Heavy Copper PCB (Thick Copper PCB)

Heavy Copper,usually we say is from 3-20 OZ.So far,the heaviest copper board we made was 12OZ.Heavy copper PCB used for Welding Equipment,Power suppliers,Solar Panel,Automotive,Electrical Power Distribution,Power Converters.Heavy copper board has high voltage/current ,it is very dangerours when supply power,the board must be the right copper thickness.

Heavy copper application

• Welding Equipment
• Solar Panel Manufacturers
• Power Supplies
• Automotive
• Electrical Power Distribution
• Power Converters
