Scalable spring finger contacts also known as shield fingers, grounding springs, universal ground contacts or clips for use in small PCB applications in various industries. These spring fingers are single contact SMT mounting internal connectors for providing grounding between a device and a PCB and shielding against EMI noise and static. Scalable spring fingers use a common footprint which allows easy design changes from one working height to another without requiring any extra space on the PCB. These spring fingers feature sidewalls to prevent the springs from being tangled with operator gloves and to prevent deflection during PCB transfer. A dimple on the contact enhances the contact force and PCB soldering holes increase solder strength and prevent wicking. A pick and place area on the contact allows automated assembly. The compact size of these spring fingers offers PCB space saving and allows for versatile PCB layouts. These spring finger contacts are available in 3 different styles; Type A (part numbers 2199248-X), Type B (part numbers 2199249-X) and Type C (part numbers X-2199250-X)
