Argus high precision laser trimmer for resistor adjustment LT7130
The precision laser trimming machine utilizes laser technology to engrave thin film or thick film resistors. It can measure the output voltages and current automatically according to different applications.
1. laser trimmer with high precision
•LT7130 uses high quality laser which provides excellent beam quality and very fine line width laser beam.
• Unique accuracy control mode. Using single point pulse, micro step distance and variable sampling frequency combination technology, it has a higher tuning resistance precision under the premise of in guarantee adjustable resistance speed.
2. laser trimmer with high speed
• Advanced laser has high beam quality and repetition frequency. In guarantee dots overlap rate of circumstances, it can guarantee a high trimming speed.
• Coarse and fine trimming process can be set by software. According to the characteristics of
resistance the proportion of coarse and fine trimming can be set to get higher trimming speed
• High precision step-by-step repeat institutions, Air suspension movement, no friction, moving velocity and acceleration fast.It can realize chunks unit circuit loop iteration adjustable resistance, realize the true high-speed adjustable resistance function.
• Unique measurement control technology.
3. laser trimmer software programmable
• With industry powerful software programming function, facing various applications functional adjustments, it easy release customer's special demand, and high automation operation.
• May to the laser power, sports, measurement range etc,it can realize programming
automatic control.
4. laser trimmer , high reliability, high stability
• Laser power output stability, high reliability
• Using special granite pedestal, it can effectively reduce the inertia vibration produced by the workbench start and stop and accelerate’s process. At the same time,it can keep temperature stability.
5. laser trimmer , low operation and maintenance cost
• High efficiency, low energy consumption, save the cost, Laser lightning conversion efficiency is 30%.Air cooled, equipment power is less than 1KW. Average power consumption less than 10 degrees,which is 10% of the flash lamp pumped solid laser. Long-term use of
available to users save large amount of energy consumption expenditure, reduce carbon emissions, long service life and stable performance, no maintenance, reduce downtime.
