Rocket-PCB, a leading name in the PCB industry, specializes in providing cutting-edge solutions for high-power and high-current applications. As the demand for server power supply boards and other PCBs with exceptional heat resistance and dissipation capabilities continues to rise, the preference for heavy copper PCBs has become evident. Heavy copper PCB fabrication presents unique technical challenges, making it a true testament to Rocket-PCB’s expertise and innovation in PCB technology.

The Significance of Heavy Copper PCBs

Heavy copper PCBs, featuring copper thickness of ≥ 3oz, have gained prominence due to their superior thermal properties and ability to handle high currents effectively. These attributes are especially crucial in applications where power boards must withstand elevated temperatures and deliver stable performance. However, the thick copper characteristic brings forth numerous processing complexities during PCB production, particularly in the lamination process.

Lamination Challenges and Traditional Methods

In traditional production methods, the lamination process for heavy copper PCBs can be troublesome. After laminating the large copper-free areas, issues such as cavities and uneven thickness may arise, hampering the graphic design, PP selection, and lamination program matching. Additionally, the laminator’s temperature rise and vacuum capacity, inner layer glue solution, residual copper rate control, and withstand voltage requirements all impose significant limitations and require careful consideration during the engineering of thick copper PCBs.
