Designed as a low cost option for automated chemical processing, JST’s Rear Linear Automated (RLA) Wet Bench works well with high volume production at an affordable price. This chemical wet bench allows for accurate process control, high throughput and production flexibility by providing multiple lot processing simultaneously with a variety of processing parameters.
The RLA supports semi-automated or automated operation with a variety of integrated wafer input and output requirements. As with all JST wet benches, they are designed for easy maintenance activities and comes with our standard 24/7 Technical Support.
