    This paper presents a method for creating planar, fluidic devices by bonding together laminations created with the nickel electroforming method. The fluid amplifier (throat width=.002″[50.8 microns], aspect ratio=1, operated in the laminar region using oxygen at 10 psig [69 KPa]) is created by sandwiching together several, several .001″ [25.4 microns] thick laminations. These laminations contain the fluid amplifier, vents and transfer channels. The laminations are initially coated with an adhesive, which acts as a bonding agent when subjected to heat. Special pins are used to insure proper alignment. The entire process is performed in a clean room environment to minimize problems. The proportional fluid amplifier is made bistable by introducing positive feedback.
