Thin Copper PCB for High Current Applications

When a circuit board needs to deal with high current, it should be made with thick copper.thick copper pcb Thicker copper increases the electrical conductivity of the PCB and reduces losses. It also allows for larger current-carrying cross-sections and encourages heat dissipation. This type of PCB is known as a thick copper pcb and is used in high-power applications such as EV chargers, power storage systems, and more.

This type of PCB is different than standard PCBs in that the copper layers are much thicker, 3 ounces or more per square foot (ft2). The thickness of each layer is a critical factor when deciding on the material to use for your circuit boards. In addition to the copper thickness, other important factors include the substrate material and the design of the traces. The choice of the right material and copper thickness will ensure that your boards can handle the highest possible current.

There are many online tools that can help you determine how thick your copper layers need to be. Some of these tools allow you to enter a trace width and length and will automatically calculate the required copper thickness for that size. However, it is important to remember that these tools are not perfect and may have some limitations. The best way to determine the required copper thickness for your circuit board is to consult a PCB manufacturer or engineer.

Typical PCBs are made with 1oz of finished copper on each layer. This is enough to meet most designs. But if your design requires higher voltages, resistance, or impedances, you might need to consider using thicker copper. There are many benefits to choosing a thicker copper PCB, including reduced losses, increased mechanical strength at connector sites, and superior thermal management.

The process of producing a thick copper PCB is similar to that of creating a standard PCB. The differences come from the materials and the manufacturing processes. Thicker copper requires specialized etching and plating techniques to ensure that the traces have proper sidewalls and undercuts.

To make a thick copper pcb, the manufacturer starts by prepping the materials and designing the inner layers on a computer program. The manufacturer then laminates the layers together with a photographic dry resist. After this, the manufacturer drills holes and assembles the board.

While the thick copper PCB is more expensive than the standard board, it provides several advantages over other types of circuit boards. Unlike the standard FR-4, thick copper allows for more current-carrying capacity. It also allows for more complex switches and better heat distribution in the board. It is also more durable, and it can withstand extreme special environmental conditions.

Heavy Copper PCBs can be designed with finely laid out structures on the outer layers and thicker copper layers on the inner layers. This enables designers to create the high-current circuits they need while improving the board’s overall performance and life. This technology can also reduce failures due to thermal stress, which is the most common cause of circuit board problems.
