Web1) For PCB boards that need to be inserted and removed frequently, gold fingers usually need to be plated with hard gold in order to increase the wear resistance of gold fingers. 2) The gold finger needs to be chamfered, usually 45°, and other angles such as 20°, 30°, etc. If there is no chamfer in the design, there is a problem. WebIt specifies the range of variation in the gain of a device over the frequency range. Variations in gain over a specific bandwidth can cause issues as different frequency signals will not be amplified equally. distortion in the transmitted signal because frequency components will not be amplified equally.
