CCL Press Plates for Copper Clad Laminate Production
CCL Press Plates are core tooling for precision CCL lamination, evenly spreading heat and pressure to prevent copper foil wrinkling, delamination and bubbling. Available in electric and thermal oil heating structures, they boast ultra-high flatness, superb high-temperature & pressure resistance and anti-deformation performance after repeated pressing. We produce 1.0–2.0mm thin plates and 7–10mm heavy backing plates from Grade 3 stainless steel or high-strength alloy steel, with standard mirror/matte surfaces and custom light textures for dedicated CCL and PCB precision lamination lines.
What is CCL Press Plates
CCL Press Plates are core precision tooling dedicated to copper clad laminate lamination. They evenly distribute heat and pressure throughout the pressing process to effectively eliminate common defects such as copper foil wrinkling, panel delamination and bubbling. We supply two heating structures: electric heating and thermal oil heating. Engineered with ultra-high flatness, outstanding high-temperature and pressure resistance, and excellent anti-deformation capability under repeated cyclic pressing, these plates deliver stable and consistent lamination quality for professional CCL and PCB production lines.
Product Characteristics of CCL Press Plates
1
High Flatness
Strict flatness control ensures uniform pressure and heat distribution across the entire board surface, avoiding uneven lamination and improving overall panel consistency.
2
Surface Precision
Adopts high-precision mirror and matte finishes with customizable subtle textures. The smooth, defect-free surface prevents board scratches and guarantees excellent CCL surface quality after pressing..
3
Thermal Stability
Manufactured from premium Grade 3 stainless steel and high-strength alloy steel. The materials maintain stable physical performance under continuous high-temperature and high-pressure working conditions.
4
Long Service Life
Features strong fatigue resistance and minimal deformation after long-term repeated pressing cycles, effectively reducing replacement frequency and lowering production costs.
Product Specifications
- Thermal Stability: Resists thermal deformation under sustained high-temperature operation, maintains stable heat conduction for consistent lamination effects.
- Flatness: Ultra-high flatness standard eliminates local pressure deviation and ensures uniform lamination on large-format CCL panels.
- Thickness Tolerance: Controls extremely tight thickness tolerance, supporting super stable stacking and multi-layer continuous pressing.
- Mirror Finish: High-precision mirror surface delivers flawless CCL appearance, no indentation, no streaks, and meets high-end substrate production requirements.
Compatible CCL Types
