JST's Fully Automated Stations

Pre Diffusion Clean with IPA Vapor Dry

JST's linear transfer systems are designed for process stations using more than three or four baths. The linear transfer is designed to be fully automatic and can pickup and drop off product at the various baths as required. The system allows for the programming of multiple simultaneous process functions. The horizontal motion mechanism houses a "zero backlash" drive which is driven directly from the motor through an attached gear. The vertical motion is accomplished using a ballscrew which employs a ball nut riding on recirculating ball bearings. This system is efficient for speed, loading and cycling. The recirculating ball bearings eliminate any torque loading on the linkage while providing a smooth motion when moving the product up or down. A brake is provided to hold the product in the vertical axis while loading or unloading. An operator places the product onto the load station. The product is then processed through the preprogrammed recipe sequences. The program can allow for the product to be dropped off for manual retrieval or temporarily held in a bath while the transfer arm performs another function.
