Abstract

Known fluidic logic elements require machine parts or photoform glass, both expensive techniques. The present technique employs multilayer ceramic technology to form the fluidic channels. First, the ceramic green sheets are selectively punched in order to provide the desired lines and holes. Then the individual sheets are assembled and laminated into solid stacks. Finally, the laminate is sintered to produce the logic element. This procedure provides a logic block comprising inlet and outlet ports 10 and 12, respectively. The ports access a fluid channel 14 formed in the multi-layer ceramic block 16. The resulting structure is thermally and chemically stable and economical to fabricate, due to the process simplicity of channel formation.
