Product Description
Custom PCB Grounding Shrapnel – Stainless Steel Stamping for Circuit Board Grounding
Tingfeng Hardware provides custom PCB grounding shrapnel, manufactured from stainless steel 301 through precision stamping and bending forming processes. The shrapnel is used for circuit board grounding connections, EMI shielding grounding, and ESD electrostatic discharge protection, ensuring electromagnetic compatibility and reliability of electronic devices. With 16 years of precision manufacturing experience, products comply with ISO 9001 and RoHS standards, with custom designs supported per drawings.
Product Overview
PCB grounding shrapnel are key components for achieving low-impedance grounding connections between circuit boards and chassis/shielding covers in electronic devices. Our shrapnel uses stainless steel 301 (combining elasticity and strength), formed into U-shape, L-shape, or custom shapes through precision stamping, fitting along PCB edges or mounting holes for grounding. Tin or gold plating ensures low grounding resistance (≤10mΩ) and oxidation resistance. The shrapnel design provides stable clamping force, maintaining reliable grounding connections even during device vibration or temperature changes. Each shrapnel undergoes 100% dimensional inspection and grounding resistance testing, suitable for various electronic modules requiring EMC/EMI protection.
Features & Advantages
| Feature | Advantage to You |
