Heavy Copper PCB introduction: 

Thick copper PCBs have finished copper weights of over 4oz (140μm), compared to the 1oz (35μm) and 2oz (0μm) copper weights typically found in standard boards. The extra copper thickness allows the PCB to carry more power, establish high thermal circulation, and perform complex switches in a small space.

Heavy copper PCBs are highly used for high power and current applications in power supplies, welding equipment, electrical power distribution, power converters, solar panel devices, medical, automotive, aviation and etc. because the heavy copper layers are helpful for controlling the thermal dissipation and running high power and current. Our heavy copper PCB manufacturing service covers single-sided, double-sided and multilayer PCBs.

Benefits of Heavy Copper PCBs: 

Heavy base copper PCBs offer several advantages such as:

• Reduced wired buss configurations lead to small PCB size
• Easy integration with high-power circuits and control circuits
• Enhanced thermal resistance reduction with addition of copper plating in the heat vias
• Increased current carrying capacity, as well as endurance to thermal strains
• Reduced layer count due to easy incorporation of multiple copper weights on a single layer
• Enhanced mechanical strength in PTH Holes and connector sites
• Allow use of exotic materials to their full potential without causing circuit failure
• Heavy copper plated vias carry high current through the circuit board, as well as help transfer heat to the heatsink in the exterior.
• The PCBs can withstand high thermal cycling

Industrial Applications Using Heavy Copper PCBs: 

• Solar Power Converters
• Overload Relays
• High Power Rectifiers
• Power Converters for Railway Electrical Systems
• Safety and Signal Systems
• Traction Converters for Railway Applications
• Protection Relays
• Excitation Systems for Power Regulators
• HVAC Systems
• Nuclear Power Applications
• Weapons Control Systems
• Power Supplies for Radar Systems
