The "FuzzProbe" Improved Fuzz Button Technology Tecknit has taken Spring Probe technology to the next level by encasing the power of Fuzz Buttons in a plastic bodied FuzzProbe. The Fuzz Button acts as an electrical spring connection within the probe. FuzzProbes are available for pitches to 1.00mm. Configurations include BGA, LGA, and RF Coaxial. Key Advantage: FuzzProbes are replaceable without socket removal from the PCB.
