This paper provides a review of techniques and technology relevant to the field of micro-devices assembly (MDA). MDA is an emerging domain of importance which is expected to have a substantial impact on a range of industrial fields including sensors, surveillance devices, and semiconductor devices. This paper provides a review of a cross-section of research including micro-gripping design and manipulation techniques, work cell design and factory automation, selfassembly techniques, and virtual reality-based approaches in micro-assembly. A discussion of the key challenges for this domain along with directions for future research is also provided.

“…The need for increased production conformity, or yield, leads to the implementation of (universal) micro assembly cells. Much effort has been performed to design these universal assembly cells that meet the agility of human operators [15,[17][18][19][20][21][22][23][24][25][26][27]. Secondly, cost analyses have been performed to justify the application of these cells in an economical context [16,28,29].…”

Abstract. Unlike manufacturing technology for semiconductors and printed circuit boards, the market for traditional micro assembly lacks a clear public roadmap. More agile manufacturing strategies are needed in an environment in which dealing with change becomes a rule instead of an exception.In this paper, an attempt is made to bring production with universal micro assembly cells to the next level. This is realised by placing a larger number of cells, called Equiplets, in a "Grid". Equiplets are compact and low-cost manufacturing platforms that can be reconfigured to a broad number of applications.Benchmarking Equiplet production has shown reduced time to market and a smooth transition from R&D to Manufacturing. When higher production volumes are needed, more systems can be placed in parallel to meet the manufacturing demand. Costs of product design changes in the later stage of industrialisation have been reduced due to the modular production in grids, which allows the final design freeze to be postponed as late as possible.The need for invested capital is also pushed backwards accordingly.

This paper is to present the evaluation of a TiNi Shape Memory Alloy (SMA) spring as actuator for the gripping manipulation. The SMA spring employed was a TiNi tensile spring which has a diameter of 50 mm wire and 350 gram hanging mass. The gripper fabricated consists of two fingers and each finger is actuated by the SMA spring. The total angular displacement of the gripper is 30 0 . The power consumptions, the movements and force generations experimentations have been conducted. The DC signal and PWM signal with 12, 12Hz, 25Hz, 125Hz, 250Hz and the 1150Hz have been employed for driving the SMA. The experimental results indicated that the 125Hz of PWM signal was likely to be had a better performance than the other signals. The 125Hz PWM signal generated faster movement, lower power consumption, and constant rate of force. In this study, closed-loop control for gripping manipulation was also conducted. The close loop controller used is PID controller. The Ziegler-Nichols method has been used to predict the optimal gain of the controller, but the best performance was determined by experimentally tuning of the gains. The experimental results indicated that the PID controller is likely to be reliable controller for gripping manipulation of the SMA spring. To obtain the better performance, it is important to consider the SMA cooling responses and the long time of retain in certain position of the gripper.
