Advantages of Thick Copper PCBs

Increased Current Carrying Capacity

Handle higher currents without increasing board temperature, essential for power electronics applications.

Higher Endurance to Thermal Stress

Withstand elevated temperatures and thermal cycling without degradation or failure.

Higher Heat Dissipation

Effectively distribute and dissipate heat across the board, improving overall thermal management.

Higher Mechanical Strength

Enhanced structural integrity at plated through holes (PTH) and connector points.

Additional Benefits

  • On-Board Heatsinks: Possibility of integrating heatsinks directly onto the PCB structure
  • Reduced Product Size: Eliminate external power distribution cables and metal sheets
  • Improved Reliability: Fewer wiring connections mean fewer potential failure points

Fabricating Thick Copper PCBs

Every thick copper PCB is a special PCB requiring unique conductive materials, substrate materials, and special production processes different from conventional boards. We use thick copper plating to increase copper weight in sidewalls of vias and plated through holes, helping reduce layer count.

Additive Manufacturing Technique

To overcome the undercutting problem present in traditional subtractive manufacturing, Xekera Systems uses the additive manufacturing technique, where we build up thick copper using a plating process. This ensures rectangular cross-sections rather than trapezoidal shapes.

Using thick copper plating, we can integrate high currents and control circuits, thereby making high-density boards even with simple board structures.

Applications of Thick Copper PCBs

Manufacturers of high-power electronic products require thick copper boards for solving thermal efficiency problems. They use thick copper PCBs mainly in:

Power Supplies
Power Modules
Automotive Electronics
Industrial Controls
High-Power LED Lighting
Solar Panel Inverters
Motor Controllers
Battery Management Systems

Rather than using cables and metal sheets for distributing power, manufacturers depend on thick copper PCBs, which not only improves productivity but also reduces expensive wiring and helps miniaturize products.
