Twisted mounting shielding fingerstrip Manufacturing
Manufacturing twisted fingerstrips involves several steps, focusing on creating a product that effectively shields against electromagnetic interference (EMI) while maintaining flexibility and ease of installation:
1. 재료 선택:Beryllium-Copper Alloy,It’s ideal for applications requiring high EMI shielding effectiveness.
2. Wire Preparation:Choose wires with the appropriate diameter and length according to the design specifications.
3. Forming the Coil:Wind the wire around a mandrel or former to form the initial coil shape.
4. Heat Treatment: Optionally, heat treat the coiled wire to increase its hardness and wear resistance, enhancing the spring’s longevity and performance.
5. Cutting and Shaping
(1) Cutting to Length: Cut the coiled wire to the required length.
(2) Shaping: Twist the ends of the wire to create the characteristic twisted configuration of fingerstrips.
6. Finishing
(1) Surface Treatment: Apply surface treatments like plating or coating if necessary.
(2) Packaging: Package the finished twisted fingerstrips securely.
7. Quality Assurance
Testing: Involve measuring the spring constant, conducting bend tests, and evaluating the shielding effectiveness at various frequencies.
