Semiconductor Robot Sales & Service

US Digital Designs provides support for the Brooks Automation Orbitran, ZBot and ZBot II wafer transfer robots, as well as our own improved model, the ZBot II+.

Are you experiencing any of these common issues with your Orbitran or ZBot robots?

We don’t just fix it. We make it better.

We’ve partnered with Brooks Automation, Inc. to tackle these problems head-on, and our collaboration has resulted in a totally revitalized ZBot product line. ZBot customers who work with USDD to refurbish their units report minimal downtime, decreased turn time, and increased satisfaction.

When we refurbish your ZBot, we enhance the unit to meet our own design-improved specifications for that particular model. Alternately, you can choose to replace your ZBot I or ZBot II with USDD’s ZBot II+, a new-manufacture unit with improvements that go beyond the upgrades we offer for ZBot II refurbishments.

All ZBot II and II+ units can drop-in replace each other, and the ZBot II+ can drop-in replace the ZBot I.

When we rebuild your ZBot, we make significant improvements to extend the life and reliability of every part of the unit. Every design-enhanced rebuild project we do receives the following upgrades:

Servo motors
Wiring harness
Vacuum board
Reduction gear assembly
Repeatabiity & accuracy

Wiring harness

E/R Cable Harness Assembly

USDD’s upgraded cable harness assembly comes with a new power distribution circuit board, for a more reliable solution to the problem shown above.

Vacuum board

Wafer Detection / Vacuum Board

OEM vacuum board

 

USDD’s new design for the vacuum system includes manual overrides, LEDs, and high-efficiency solenoids.

Reduction gear assembly

Repeatabiity & accuracy

Repeatability & Accuracy

Accuracy & repeatability issues are primarily the result of worn lead screws. We replace lead screws and bearings with every rebuild.

 

Linear slide bearings are replaced with new bearing system.

 

We replace worn old OEM belts with new larger, stronger Kevlar® belts.

 

Worn pulleys, radial bearings, and belts are all replaced and properly aligned.

Our commitment to quality

USDD is committed to continuous quality improvement for our ZBot and Orbitran product lines. Our experience and expertise is a definite advantage but the true advances come from our relationships with Brooks Automation Inc., our suppliers, and the robot end users.

Listening and working with the end users is a fantastic source of knowledge. We strive to continuously improve our products by attacking the sources of ware and fatigue. Our test stand apparatuses allow us to test the robots for basic operations or even extreme conditions when necessary.

Every robot spends a minimum of 24 hours on a test bench. We physically pass thousands of wafers, monitoring repeatability, accuracy and reliability. In addition, we can test new ideas to improve the robots under conditions very similar to field operation.
