Application of Thick Copper PCB

Introduction

In the realm of electronic circuitry, the use of Thick Copper PCBs has emerged as a game-changer, particularly in power electronic equipment and power supply systems. This trend is evident in the PCB industry’s shift towards finished copper weights exceeding 4oz (140μm), a significant leap from the standard 1oz (35μm) or 2oz (70μm) copper weights found in conventional PCBs.

The integration of extra copper in PCBs enables these boards to handle significantly higher currents and distribute heat more effectively. This capability is crucial for achieving complex functionalities within limited spaces. Moreover, Thick Copper PCBs offer a myriad of advantages, including enhanced mechanical strength at connector positions, the ability to reduce product sizes by combining multiple copper weights on the same circuit layer, and the use of exotic materials to maximize capacity while minimizing the risk of circuit failure.

Advantages of Thick Copper PCBs

1. Increased Current Capacity: The additional copper in Thick Copper PCBs allows for a higher current-carrying capacity, which is essential for high-power applications. This capability enables the PCB to handle larger currents without overheating or performance degradation.
2. Enhanced Thermal Resistance: Thick Copper PCBs exhibit better resistance to thermal strain compared to standard PCBs. This enhanced thermal resistance ensures reliable performance even under high temperatures, making Thick Copper PCBs suitable for applications where heat dissipation is critical.
3. Improved Heat Dissipation: The increased copper content in Thick Copper PCBs enables better heat dissipation. This is crucial for maintaining optimal operating temperatures in electronic devices, as excessive heat can lead to performance issues and component failure. Thick Copper PCBs effectively dissipate heat, ensuring the longevity and reliability of the circuitry.
4. Mechanical Strength: The presence of thick copper enhances the mechanical strength of the PCB, particularly at connector positions and plated-through holes (PTH). This increased mechanical strength reduces the risk of damage during handling and installation, improving the overall durability of the PCB.
5. Product Size Reduction: By combining multiple copper weights on the same circuit layer, Thick Copper PCBs enable the production of smaller-sized products with complex functionalities. This size reduction is achieved without compromising the performance or reliability of the PCB, making heavy copper PCBs an ideal choice for compact electronic devices.

Overall, the advantages of heavy copper PCBs make them a preferred choice for high-power applications where reliability, heat dissipation, and current-carrying capacity are paramount. Their ability to handle large currents, resist thermal strain, dissipate heat effectively, and provide mechanical strength makes them an indispensable component in modern electronic devices.
