Fiberglass for CCL/PCB board Impregnation Lines are primarily classified into two types: vertical and horizontal. The fundamental distinction lies in the orientation of the drying oven and the material's travel path, with each configuration tailored to the specific production characteristics of high-strength fabric substrates versus low-strength paper substrates.
Vertical Impregnation Lines
Core Advantages Fiberglass for CCL/PCB board Impregnation Line
Adapted for Fiberglass Fabric: Specifically designed for fiberglass fabrics with high tensile strength, capable of withstanding heavy wet-state loads during vertical traction (approximately 2 to 3 times the weight of the dry fabric).
Minimal Footprint: Features a vertical layout; the floor area required is only 1/3 to 1/2 that of a horizontal system, thereby saving valuable factory space.
High Thermal Efficiency: Utilizes vertical hot-air convection to maximize thermal energy utilization and minimize energy consumption.
Thorough Drying: The oven features significant height and a long dwell time, ensuring complete solvent volatilization and minimal residual volatile content—even when processing thick fabrics or materials with high resin content.
High Speed: Typical line speeds range from 30 to 80 m/min, making it ideal for large-scale mass production.
Copper-Clad Laminates (CCL): Electronic-grade fiberglass prepregs (semi-cured sheets), such as FR.
Insulation Boards / Laminates: Electrical insulation materials and composite materials for new energy applications.
Thick / Heavyweight Fabrics: Thick, high-basis-weight fiberglass fabrics, such as types 7628 and 2116.
High Facility Requirements: Requires sufficient ceiling height (typically ≥ 8 to 15 meters).
Strict Tension Control: Vertical traction generates high tension forces, imposing stringent requirements on both the equipment and the tensile strength of the fabric being processed.
Facility-Friendly: Low profile (suitable for standard factory buildings); easy to install and maintain.
Low Tension:Minimal horizontal traction tension prevents stretching and deformation of the material.
Air Cushion Support: Select models utilize hot-air cushion technology, ensuring non-contact processing of the fabric surface—preventing sticking to rollers and maintaining a pristine finish.
High Versatility:Capable of processing a wide range of materials, including thin fiberglass cloth, decorative paper, and kraft paper.
Thin Fiberglass Cloth: Ultra-thin, low-basis-weight fabrics such as 1080 and 106 grades.
Paper-Based Materials:Melamine paper and insulating paper (a primary application).
Small-Batch / Multi-Variety Production:Ideal for facilities with limited floor space or ceiling height restrictions.
Large Footprint:Extends horizontally, requiring a factory building with significant length.
Low Thermal Efficiency:Horizontal circulation of hot air leads to substantial heat loss and high energy consumption.
Drying Limitations:When processing thick fabrics or materials with high resin content, solvent volatilization may be incomplete, leading to residual solvent issues.
