High Precision Automation For MEMS Manufacturing

DWFritz develops custom automation assembly, inspection, and metrology equipment for MEMS (Micro Electromechanical Systems) industry applications that reduce manpower, speed throughput, and improve quality. DWFritz excels as an Engineered-To-Order design and build firm for the micron-level precision often required for MEMS manufacturing.

Over 100 Systems Built For The MEMS Industry

We have designed and built more than 100 sophisticated, custom turnkey automation systems for MEMS assembly, inspection, and metrology applications. Our MEMS clients will tell you that our solutions are simple, elegant, and they work. We know the technology, what works, and how to use it. We routinely take proven engineering technologies and apply them in creative ways to solve our clients’ most difficult MEMS challenges.

Potential DWFritz Automation MEMS industry applications:

Inkjet Printers - use of piezoelectrics or thermal bubble ejection to deposit ink on paper.
Accelerometers in modern cars for a large number of purposes including airbag deployment in collisions.
Accelerometers in consumer electronics devices such as game controllers, personal media players / cell phones and a number of digital cameras. Also used in PCs to park the hard disk head when free-fall is detected, to prevent damage and data loss.
MEMS gyroscopes used in modern cars and other applications to detect yaw; e.g. to deploy a roll over bar or trigger dynamic stability control.
Silicon pressure sensors; e.g. car tire pressure sensors, and disposable blood pressure sensors.
Displays; e.g., the DMD chip in a projector based on DLP technology has on its surface several hundred thousand micro mirrors.
Optical switching technology that is used for alignment for data communications.
Bio-MEMS applications in medical and health related technologies from Lab-On-Chip to MicroTotalAnalysis (biosensor, chemosensor).
Interferometric modulator display (IMOD) applications in consumer electronics (primarily displays for mobile devices). Used to create interferometric modulation - reflective display technology.

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.
