Abstract

The application of plastic microfluidic chips can be extended with quartz capillaries connected at the end of their microchannels, e.g. UV absorption detection method can be carried out, which responds to almost 80% chemical compounds in detection. Experiment system for automatic microassembly was developed to carry out the task of joining capillaries to plastic microfluidic chips. Experiments were done with different viscosity of UV curing adhesives, dispensing time, dispensing pressure and curing time. Suitable process parameters were determined. Visual feedback is employed in the microassembly system. The automatic positioning of capillary with visual information is described. The problems met during assembly are discussed and solved
