Abstract: A new architecture for packaging surface micromachined electro-microfluidic devices is presented. This architecture relies on two scales of packaging to bring fluid to the device scale (picoliters) from the macro-scale (microliters). The architecture emulates and utilizes electronics packaging technology. The larger package consists of a circuit board with embedded fluidic channels and standard fluidic connectors (e.g. Fluidic Printed Wiring Board). The embedded channels connect to the smaller package, an Electro-Microfluidic Dual-Inline-Package (EMDIP) that takes fluid to the microfluidic integrated circuit (MIC). The fluidic connection is made to the back of the MIC through Bosch-etched holes that take fluid to surface micromachined channels on the front of the MIC. Electrical connection is made to bond pads on the front of the MIC.

Abstract: A tank for holding a liquid for a predetermined and relatively long time in a continuous flow process. The tank includes an inner compartment with an inlet and an outer compartment with an outlet. The outer compartment encloses the inner compartment except its inlet. The liquid enters through the inlet and is forced upwardly in a non-preferential flow, it overflows to the outer compartment and comes out through the outlet.
