A modular approach to high throughput microsystems
… to assemble with the 96 CFPCR array by using passive alignment structures to perform a systematic performance. The passive alignment structures including three pairs of v-groove and hemisphere-tipped post was studied and modified to ensure a smooth passage for mass, momentum, and energy of …

On the development of a low-cost lithographic interferometer
… low-cost blue laser diode. Additionally, the passive alignment of a lens tube is utilized to simplify the construction of a spatial filter. The resulting custom-built interference lithography tool is able to print large-area (~ cm2 ) periodic patterns. The tool has a small footprint (~0.2 M2 ) …

Microassembly technology for modular, polymer microfluidic devices
… For connecting modular devices, precise, passive alignment structures can be used to prevent infinitesimal motions between the devices and minimize misalignment. The motion and constraint of passive alignment structures were analyzed using screw theory. A combination of three v-groove and …

Discrete cellular lattice assembly
… a shorter assembly cycle period can be attained. Passive alignment features designed into the robot end-effectors, locomotion systems, and the discrete lattice elements reduce the precision requirements of the assembly process by opening up the acceptable error range, thereby, enabling higher …

Novel mechanical alignment and component fabrication for wavelength-selective optical switches
… This thesis develops a range of novel alignment and fabrication techniques necessary to construct an experimental two-dimensional WSS system. Where necessary these techniques are further developed to enable the cost-effective volume manufacture of commercial switching products based on …
