Abstract
Briefly, according to the invention, a laser trim system (100) for trimming printed components (112) on a circuit carrying substrate (118) is disclosed. The laser trim system (100) includes a laser source (102) for trimming the printed circuit components (112). The laser source (102) has an adjustable power level, suitable for trimming a variety of printed components. The laser trim system (100) also includes a power converter (110) for selectively measuring the power level of the laser source (102). A laser power supply (104) is also included in the laser trim system (100) for adjusting the power level of the laser source (102) in response to the measured power level. The laser trim system (100) further includes a computer (1068) for comparing the measured laser power level with pre-defined levels to determine when a change in the power level is necessary.
