ザトリミング装置。[Scope of Claim for Utility Model Registration] A continuous wave laser oscillator using a Q-switch pulse oscillation method equipped with a Q-switch element, a driver section that drives the Q-switch element upon receiving a Q-switch pulse control signal, and a laser beam ON/OFF switch. Q that receives the signal and generates the Q switch pulse control signal.
The switch pulse generation circuit and the laser beam ON/
A laser trimming device comprising: a laser beam ON/OFF signal generating means for generating an OFF signal; and a beam positioner for focusing the laser beam from the laser oscillator on a desired position on the trimming substrate; The generation means includes another ON signal having the same characteristics as the laser beam ON/OFF signal.
a shutter unit having a function of generating a /OFF signal, and blocking the laser beam when receiving a shutter ON signal between the laser oscillator and the beam positioner; and an alarm generator that issues an alarm when receiving an alarm signal. means and said two ON/OF
When the Q switch pulse control signal is output due to a circuit abnormality even though both F signals are OFF, a circuit outputs the shutter ON signal and the alarm signal to cut off the laser beam and issue the alarm. A laser trimming device comprising: means.
