Previously I’ve described two regimes in the design and manufacture of microfluidic devices; fluid circuits (FC) and integrated fluidic circuits (IFC). The former being similar to printed circuit boards (PCB) in their function, while the later are similar to integrated circuit processors (ICP) in their specialized functions and the dependence of their function on specific geometries and surface properties. Microfluidic FCs perform a variety of functions that rely less on surface properties and more on the control of pressure drops in the system.  As with PCBs in which one applies an electric potential to manage the bulk flow of electrons through the circuit, we use a pressure potential to control fluid in the circuit.

How analogous to PCBs is ALine’s fluid circuit platform?
