The MEMS technology has been developed for many years.
Micro-assembly becomes more and more important in this years.
Microfasteners play a critical role in micro-assembly due to their simple
configuration and easy to be fabricated.
The objective of this study is to utilize the phenomenon observed, that
fits the definition of the degree of freedom of general mechanisms, and to
synthesize new microfasteners employing the concept of mechanism
design. Firstly, microfasteners are analyzed based on the need. After
synthesizing new microfasteners in micro-scale, they are transformed into
compliant mechanisms in micro-scale. By establishing geometry, FEM is
applied to simulate the situation of insertion and retention, and to check if
bucking will happen. Finally, the retention force is improved by changing
the width of links. The insertion force, retention force, and stress are
considered for selecting feasible configurations. An example of
microgear set mechanism is introduced to demonstrate the assembly of
the microgear set after microfabrication process with large backlash.
