Precision Positioning and Alignment

DWFritz machines perform micron and sub-micron precision alignments and attachments not once or twice, but over a million times every day. If we can do this, can’t we solve your challenge, too?

Precision positioning is incorporated into many automation systems designed and built by DWFritz Automation. Machines capable of part placements with mean alignments below 1 micron and dispensing of liquids with precisions of ± 25 microns are developed using computationally extensive methods, combining machine vision and servo control. High precision stages, hexapods, robots, and other technologies are used to achieve high precision positioning.

Featured Projects

Ultra Precision Excise and Attach Machine

This system precisely excises small plastic parts from supply reels and attaches them to silicon wafers using a UV curable adhesive. High-performance machine vision and precision motion components enable ultra-precision alignments between the parts and wafer. A robot with a dual wafer gripper automatically moves wafers between the processing table, input cassette, and a UV flood station.

Ultra High Precision Wafer Attach Machine

This machine attaches small, thin components to the surface of a wafer using vision-guided servo control. First, an array of parts is robotically loaded into one end of the machine. The vision system then directs the X-Y-Theta table to present an individual part for pickup. The part is then placed onto an air conveyor for transport to the attach station.
