Introduction to Fingerstock
Fingerstock is a type of flexible conductive gasket that consists of a series of thin, finger - like metal strips. These strips are typically made from materials such as beryllium copper, phosphor bronze, or stainless steel. Fingerstock is widely used in the field of electromagnetic interference (EMI) shielding and grounding applications. It provides an effective way to create a low - impedance electrical path between two surfaces, which helps to prevent the leakage of electromagnetic signals and protect sensitive electronic components from external interference. Due to its flexibility, fingerstock can conform to irregular surfaces, ensuring a reliable and long - lasting seal.
