How to Use?

1. Cutting: The products can be easily cut using standard woodworking tools, such as circular saws or routers. Always use sharp, carbide-tipped blades for clean cuts.
2. Drilling: Use high-speed steel or carbide-tipped drill bits. Maintain moderate pressure and speed to prevent overheating.
3. Machining: FR4 can be milled, turned, and shaped using standard metalworking equipment. Use coolants to prevent heat buildup during machining.
4. Bonding: For assembly, use epoxy adhesives compatible with FR4 material. Ensure surfaces are clean and properly prepared before bonding.
5. Finishing: Sand edges smooth if needed. FR4 can be painted or silk-screened for labeling or aesthetic purposes.

Always follow proper safety precautions, including wearing appropriate personal protective equipment when working with the products.
