Robot system aims for semiconductor industry
The Innovative Robotics IR-800 is an advanced wafer-handling robot for high throughput and reliability in an ISO Class 1 cleanroom environment.
The W670 delivers unmatched throughput with stable quality cuts.
The system's calibrated beam field offers 25um accuracy over a 4 x 4in field and automatically controls complex multileg trims to ensure superior cut quality without microcracking.
The W670's measure and matrix instrumentation conforms to VXI form and function standards making the system ideal for precision resistor or voltage trims.
The instruments are specifically designed for high-speed and high-volume operation while providing benchmark CpK process capability.
The VXI architecture easily accommodates hundreds of VXI instruments and the W670 controller also supports IEEE and RS232 extensions.
The optical system of the W670 provides clear viewing of substrates even under low-contrast conditions.
Nondestructive edge sensing automates the alignment process and eliminates the need for operator intervention.
GSI Lumonics also offers the latest in video pattern recognition technology for quick and precise target alignment for applications such as printed circuits where component placement is not precisely repeatable.
The laser trimming system's laser spot size is adjustable from 30-50um for flexible depth of focus to enable users to optimise beam characteristics to match substrate height variations and resistor size without changing or realigning the optics.
The W670's Windows NT operating system provides system control through a highly flexible, fully data-driven spreadsheet with full graphical interface.
The spreadsheet editor greatly minimises the level of experience required to quickly set the system up to process new applications.
Users simply enter their specification into data fields and the program executes the logic according to the trim and measurement parameters from the spreadsheet.
The system can easily be reconfigured to accommodate custom production automation with three-sided access to the W670's probe and trim area enabling parts changeover to be completed quickly.
