What Is the AUREL ALS300 Laser Trimming System?
The AUREL ALS300 trims resistor values and circuit functions to target by laser, measuring in real time as it cuts. Beyond ceramic and PCB substrates, it also works on glass, silicon and plastics. In addition, it can drill LTCC/HTCC green tape and laser-mark parts.
What Are the Key Features of the AUREL ALS300?
Above all, the ALS300 is built for fast, accurate trimming. Key features include:
- Q-switched, diode-pumped Nd:YVO4 laser (1064 nm or 532 nm), or a 20 W fibre source
- X/Y linear drive plus galvanometer beam positioning, with a 100 x 100 mm galvo field and parts up to 150 x 150 mm with handling
- Versatile probing with up to 4 flying probes, a probe card holder (AUREL or third-party), or both
- Cut shapes such as I, L, double, serpentine and multiple shave cuts, with target value, tolerance and pre-stop settings
- Ohmic and functional (active) trimming, as well as Blast and Measure mode
- Resistor map import from CAD (.dxf, .dwg), with pattern recognition and advanced trim sequences
- High Speed version trims up to 10 resistors per second in passive mode
- Optional in-line integration with loader/unloader and conveyor modules
What Is the AUREL ALS300 Used For?
Because it handles both passive and functional trimming, the ALS300 suits applications such as:
- Thick and thin film hybrid and resistor trimming
- Functional trimming of SMD chip resistors
- Ohmic and functional trimming of RF and ASIC modules
- Sensor elements for automotive and industrial applications
- LTCC/HTCC through-hole drilling and green tape routing
- Laser marking on ceramics, metals and plastics
What Options Are Available for the AUREL ALS300?
In addition to the standard configuration, you can fit the ALS300 with the following options:
- Data logging and SPC software
- Industry 4.0 data transfer
- Advanced marking software
- Automatic door and autofocus
- Motorised Z axis
- Step and repeat table with linear motors
- Power meter
- Exhaust and filtering
- Optics for thin-film trimming
- Pressure and temperature chambers
- Remote assistance
- Automatic handling (AH150 loader/unloader)
Why Choose the AUREL ALS300 for Resistor and Hybrid Trimming?
With a maximum positioning speed of 80,000 mm/s and cut speeds from 0.4 to 200 mm/s, this laser trimming system suits production lines that need fast, accurate trimming of chip resistors, hybrids and RF circuits. It also measures in real time during cutting. As a result, together with flexible probing options and programmable cut shapes, it supports both simple ohmic trimming and more complex active, functional trimming work.
