G10 FR4 fiberglass sheet

The key advantages of using G10/FR4 fiberglass sheets in electrical and electronic devices:
1. Excellent dimensional stability:
G10/FR4 has a low coefficient of thermal expansion, meaning it resists expansion and contraction over a wide temperature range. This helps maintain spacing and alignment of printed circuit board traces and components.
2. High tensile and flexural strength:
The woven fiberglass construction gives G10 great mechanical strength as a structural material. It resists warping and deforming under load.
3. Flame resistance:
The FR4 grade is self-extinguishing and does not promote flames. This is critical for safety in electrical products.
4. Electrical insulation:
The epoxy resin provides very good electrical insulation, ideal for separating conductive PCB traces. Has high dielectric strength.
5. Moisture resistance:
Absorbs very little moisture, retaining good dielectric properties. Important for reliability.
6. Easy to machine and fabricate:
Can be readily machined, drilled, cut to shape using standard tools. Enables easy prototyping and fabrication.
7. Good thermal conductivity:
Efficiently conducts heat away from components mounted on it. Helps with cooling.
