How does the composite copper foil equipment control the accuracy in terms of copper foil thickness and uniformity?

In terms of controlling the thickness and uniformity of copper foil, composite copper foil equipment needs to rely on precise mechanical structure, sensor technology and intelligent automatic adjustment system. The uniformity of copper foil thickness has an important influence on the conductivity, mechanical strength and subsequent processing performance of the final product, so precision control is a key issue that must be solved in the production process.

The equipment is usually equipped with a high-precision rolling system, which realizes the continuous compounding and pressing of copper foil through precisely designed rollers and mechanical transmission structures. During the rolling process, the gap control between the rollers is an important factor in determining the thickness of the copper foil. By adjusting the pressure and position of the rollers, the copper foil is evenly squeezed during the compounding process, so as to achieve precise control of the thickness. High-end equipment uses advanced hydraulic or electric adjustment devices to adjust the roller gap at the micron level to ensure that the thickness of the copper foil remains within a very small error range.

The control of thickness and uniformity also depends on a high-precision online detection system. Laser thickness gauges or other non-contact thickness sensors are usually installed inside the equipment, which can monitor the thickness of each area of ​​the copper foil in real time and feed back the data to the central control system. The control system analyzes the feedback data and automatically adjusts the working parameters of the rolling device to ensure that the thickness of the copper foil remains stable at all times. Throughout the production process, real-time detection and dynamic adjustment are combined to effectively avoid thickness deviation problems.

To ensure the uniformity of the copper foil surface, the composite copper foil equipment also specially optimizes the material distribution and tension control system during the composite process. The material may be affected by uneven tension or unstable material flow during the composite process, resulting in inconsistent thickness. The equipment uses a tension control system to ensure that the copper foil and the substrate always maintain a stable stretching and running state during the composite process to prevent thickness changes caused by tension fluctuations. In addition, the material distribution device ensures that the composite material is evenly distributed on the copper foil surface, thereby further improving the overall uniformity.

Modern composite copper foil equipment is also equipped with automated control technology, which integrates the management of various parameters in the production process through a computer control system. Through multi-dimensional coordinated control of temperature, pressure, tension and thickness, the system can quickly identify and adjust small errors in production to ensure the best product quality. Combined with high-precision mechanical design and intelligent feedback adjustment, these technologies jointly ensure the precise control of copper foil thickness and the stability of surface uniformity.
