This precision, large open aperture (hollow core), low profile stage is just 65 mm (2.559 in.) high and it’s foot print is only 303 mm by 319 mm (11.929 in. by 12.559 in.) not including the motor. The rotary table of the stage has a precise pattern of threaded holes for mounting custom tooling and fixtures, and holes in the base for easy integration into new and existing applications. The diameter of the rotary table is 300 mm (11.811 in.) and the range of travel is a full 360o, and it is capable of continuous rotation. The table is driven by a smooth 288:1 worm gear and has a resolution of 0.000625o with a 10 micro-step per step stepper motor driver. The AY110-300 Rotary Stage is also available with a servo motor and optical encoder. The standard model is equipped with stepper motor and a is a knob for manual adjustment which can be replaced with an optical encoder for precision position verification.
The low cost, low profile AY110-300 Rotary Stage features a very low backlash of 0.0005o, and a positional accuracy of 0.001o, making it ideal for: laser positioning and machining, scribing, microscopy, testing, assembly, inspection, alignment, and other critical applications.

Application – Rotary Table from Intellidrives Tackles Big Wafers!
INTELLIDRIVES’s Direct drive rotary servo tables.
 |
Philadelphia, PA, — Motion Control Components and Systems – The ACR-335UT direct drive rotary table from IntelLiDrives adapts linear motor technology, coupled with precision bearings, to provide faster and more accurate handling of the 300 mm semiconductor wafers.
The 335 mm diameter center opening in the ACR-335UT rotary table easily accommodates large 300 mm (12 inch) semiconductor wafers, allowing for extraction of the chip dies from the wafer during semiconductor assembly manufacturing processes or dual side wafer inspection.
Presently, semiconductor assembly equipment manufacturers do only limited wafer rotation, but ACR-335UT stage goes 360°, at up to 300 rpm speed.
This large angle wafer rotation can be done without need to align wafer carrier before placement on the table, thereby increasing throughput. An XY table that carries the rotary table is used for linear Cartesian Alignment. The large open center allows equipment above and below the table to extract precut integrated circuit dies cut from the 300 mm wafer or to do dual side wafer measurement and inspection.
Today’s mechanical drive technologies used in processing 200 mm (8 inch wafers) such as gear drive, worm drive and belt all lack positioning stiffness and accuracy. While worm gear rotary tables can fully rotate wafer , it speed is in single digit rpm. Belt drives can rotate at high speeds, but low belt stiffness and high drive inertia results is low accuracy and poor dynamics.
While these characteristics could be tolerated in the past, since it was not until advent of the large semiconductor wafers that a high accurate, precise and large open aperture rotary actuator was needed.
The ACR-335UT rotary table is essentially a linear motor “curved” to form a ring. There are 16 RotoLinear motoring modules (up 24 modules can be installed for higher torque capability) within the ring that forms the motor. Axial placement of these modules along with the ultra-thin bearing system allowed design of the very low profile rotary stage.
The positioning stiffness of the direct drive ACR-350UT rotary table allows it to achieve and to maintain arc-sec accuracy at hundreds of rpm and excellent dynamics even during fast Cartesian (XY) wafer indexing.
Also vital, and the major manufacturing challenges, were the tight tolerances on the axial and radial bearings that allowed to achieve both axial and radial run-outs well under 10 microns.
AccuRing rotary tables provide superior angular positioning and are designed to eliminate backlash, friction and wear problems associated with worm, gear and belt drives. Low maintenance and high throughput characteristics of the AccuRing stage yields the lowest total cost of ownership.
Compact package and Superior design of the AccuRing rotary stages was optimized to minimize stage height. The low profile of the stage reduces total system working height. Angular contact bearings are used to maximize performance with respect to wobble, moment stiffness and friction. AccuRing stage has large clear center aperture that can be used for air or wire line feed-through or beam delivery.
AccuRing utilizes direct drive three phase planar brushless motor technology. There are no brushes to replace and no gear trains or belts to maintain. Coreless magnetic design assures smooth rotation and dynamic performance.
Accurate Positioning is assured with contact-less encoder. The motor and rotary encoders are directly coupled to eliminate coupling backlash. The low inertia and zero backlash make AccuRing the ideal solution for applications requiring frequent directional changes.
