Nanosecond Fiber Lasers for Resistor Trimming
During any manufacturing process, there is some statistical variation in the finished product. Resistor manufacturing is no different, and for many years traditional bulk and chip resistors have been tested and sorted into bins and labeled based upon these tolerances. Board mount chip resistors are also similarly tolerance using a numerical code instead of a color code, but the end result is the same. However, this is not feasible in larger format thick-film or thin-film intergraded circuits which require initial calibration, such as operational amplifiers, voltage dividers, and oscillators, where the resistors are one small detail in a much more complex arc… Read More
