7628 Fabric: High-Performance Material for Diverse Applications

7628 Fabric is a high-performance Fiberglass Fabric widely used in the fields of electronics, industry and composite materials. Due to its unique structure and excellent performance, it has become an important choice for PCB (printed Circuit board) substrates, insulating materials and reinforced composite materials.

I. Basic Characteristics

1. Material: Usually woven from E-glass (electronic-grade glass fiber), it features high insulation, high temperature resistance and corrosion resistance.

2. Woven structure: 7628 represents its weaving specification (such as warp and weft density), which belongs to a relatively coarse plain weave fabric with moderate thickness and high mechanical strength.

3. Typical parameters:

Thickness: Approximately 0.173-0.190 mm

Weight: Approximately 200-210 g/m²

Tensile strength: Balanced in both the warp and weft directions, suitable for multi-layer PCB lamination.

II. Main Applications

1. Printed Circuit Board (PCB) : As an reinforcing substrate of epoxy resin (FR-4), it is a multi-layer board used in high-end electronic products such as computers and communication equipment.

2. Insulating materials: Insulating layers used for electrical equipment such as motors and transformers.

3. Composite materials: Combined with resins to form high-strength lightweight materials, they are applied in aerospace, automotive parts and other fields.

4. Industrial protection: High-temperature resistant, anti-corrosion, and can be used for pipe wrapping, fireproof materials, etc.

III. Advantages

1. High mechanical strength: Roving weaving provides excellent tensile and tear resistance.
2. Dimensional stability: It is not prone to deformation in high-temperature environments and is suitable for precision electron lamination.
3. Electrical insulation: Low dielectric constant, suitable for high-frequency circuit boards.
4. Chemical resistance: Resistant to erosion by acids, alkalis and organic solvents.
