Epoxy glass fiber board is a high-performance composite material consisting of an epoxy resin matrix and reinforced glass fiber cloth. Known for its exceptional electrical insulation and mechanical strength, it is a cornerstone in the new energy and electronics industries.
In this guide, we dive into the core production technology that ensures the stability and durability of every sheet produced by RDS.
1. Raw Material Preparation: The Foundation
The quality of a plate is determined at the source. We select electronic-grade alkali-free glass fiber cloth treated with a coupling agent to ensure maximum bonding with the resin.
- Resin Matrix: Epoxy resin is mixed with precise proportions of curing agents and accelerators.
- Quality Control: We strictly monitor viscosity and gel time to guarantee uniform infiltration.
2. Impregnation and Semi-Curing
The glass fiber cloth is passed through a resin tank at a controlled speed. Using precision scraper pressure, the resin penetrates deep into the fiber bundles, preventing any "dry spots" or missed impregnation. The material then enters a tunnel oven to form a semi-solid prepreg.
3. Layer Stacking and Vacuum Hot-Pressing
This is the critical stage for density and thickness control. In a dust-free environment, prepregs are stacked and placed into a high-pressure lamination machine.
- Vacuum State: Removes air bubbles to ensure a dense structure.
- Temperature Curve: Heat is raised in stages, reaching approximately 170°C for complete curing, followed by a slow cooling process to prevent warping.
4. Post-Treatment and Strict Inspection
Every board undergoes CNC trimming and aging treatment to release internal stress. Our final inspection covers:
- Appearance: No scratches or delamination.
- Performance: Rigorous insulation performance and thickness measurements.
