CT-LR Laser Trimming Resistance Machine

To focus laser bean into a point, the power density of the focal plane is up to 10 - 10 w/cm2. The advantages of laser can be used to trim resistance. The laser bean through optical system can be focused on much small area, gasify the metal on the focus point in high frequency pulse. The purpose of trimming resistance can be achieved. The machine which can be used mainly for trimming resistance and capacity of thick, thin film circuit, can also be used for functional trimming of circuit parameters to raise the precision of the circuit.
