Thick film laser trim
Web1 Oct 2014 · A novel methodology for predicting the laser trim length is introduced, thereby eliminating the closed-loop control and speeding up the process and demonstrating effectiveness on an actual wafer of laser-trimmed ICs. Laser trimming is used extensively to ensure accurate values of on-chip precision resistors in the presence of process … Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit. One of the most common applications uses a laser to burn away small portions of resistors, raising their resistance value. The burning operation can be conducted while the circuit is being … See more One type of passive trimmer uses a pressure chamber to enable resistor trimming in a single run. The LTCC boards are contacted by test probes on the assembly side and trimmed with a laser beam from the … See more Often designers use potentiometers, which are adjusted during end testing until the desired function of the circuit is reached. In many … See more A similar approach can be used to program digital logic circuits. In this case, fuses are blown by the laser, enabling or disabling various logic circuits. An example of this is the IBM POWER4 microprocessor where the chip contains five banks of See more
