Reconfigurable micro-assembly system for photonics applications

Proceedings 2002 IEEE International Conference on Robotics and Automation (Cat. No.02CH37292), 2003
The assembly of parts with dimensions several hundred microns or less is a challenging problem, and has received increasing attention for applications in areas such as telecommunication, automotive, and biotechnology. Current state of the art micro-assembly systems are often specialized devices and software.

Micro Assembly Technology and System

2008
Micro assembly refers to assembling micro size objects, such as integrated electronic circuits, micro mechanical components, and micro fluidic components. These objects are usually no bigger than 10 mm. Moreover, high accuracy (e.g. 1 µm) and high speed (e.g. 1 m/sec. or 10 m/sec2) are often required.

Qualification of standard industrial robots for micro-assembly

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
Precision micro-assembly requires special tools, in order to fulfil the high demands in accuracy and control of the assembly process. A precise gripper tool, the micro-positioning system (MPS) has been developed, that makes micro-assembly with industrial robots possible. The whole assembly process can be surveyed and controlled with a vision system.

Thermal Problems in Micro Assemblies

Hybrid Circuits, 1985
Except in specific activities in electronic equipment, thermal management is not the most exciting subject for those involved in design. With micro-assembly (surface mounting of components) the cooling of components and PCB is now being seen in a new light. This paper, very rapidly, highlights the problems every designer has to take into account today.

Micro assembled Fourier transform spectrometer

SPIE Proceedings, 2009
With the trend of minimization of Fourier transform spectrometer (FTS) which is particularly pronounced in many applications, a model of a micro FTS with no moving parts is proposed and analyzed. During analyzng, the gradients which mainly introduce phase error are accounted.

Hybrid micro assembly of microchips on segmented patterns

2010 IEEE International Conference on Automation Science and Engineering, 2010
this paper reports a novel process that positions RFID chips on segmented artificial antenna pattern using hybrid assembly technology. A droplet of water is firstly dispensed to an artificial pattern composed of four pads. Then a 730×730µm RFID chip with four bumps of 20µm in height is released onto the artificial pattern using a robotic microgripper ...

A magnetic levitation actuator for micro-assembly

Proceedings of International Solid State Sensors and Actuators Conference (Transducers '97), 2002
The magnetic levitation actuator, which is composed of three layers of silicon structures and a permanent magnet, has been fabricated using micromachining technology and assembled. The top layer consists of a groove and many pairs of small square coils which are used to generate driving forces.

Hexsil tweezers for teleoperated micro-assembly

Proceedings IEEE The Tenth Annual International Workshop on Micro Electro Mechanical Systems. An Investigation of Micro Structures, Sensors, Actuators, Machines and Robots, 2002
This paper describes essential components of a prototype system for teleoperated microassembly. High aspect ratio molded polysilicon (hexsil) tweezers with integrated in-situ phosphorous doped thermal expansion actuator beams and piezoresistive polysilicon strain gages for tactile feedback are described. The tweezers are normally closed, and require 75
