As the demand for high power products grows, so does the demand for thick copper PCBs. At Xekera Systems, we manufacture regular PCBs with finished copper weight of 1-3 oz (35-105 µm) and thick copper PCBs with finished copper weight of more than 4 oz (140 µm). These boards enable higher current conductivity without raising board temperature.
Handle higher currents without increasing board temperature, essential for power electronics applications.
Withstand elevated temperatures and thermal cycling without degradation or failure.
Effectively distribute and dissipate heat across the board, improving overall thermal management.
Enhanced structural integrity at plated through holes (PTH) and connector points.
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.
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.
Manufacturers of high-power electronic products require thick copper boards for solving thermal efficiency problems. They use thick copper PCBs mainly in:
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.
For applications requiring high cooling, high current, and high power, thick copper PCBs play an important role. Contact us today to learn more about our advanced thick copper PCB capabilities.
