Adanced Manufacturing Technology of EFIs

      We’ve provided a method for the fabrication of the integrated EFI. Magnetron sputtering, photolithography, and Chemical vapor deposition (CVD) technique has been employed for the fabrication of an integrated exploding initiator with a parylene-C flyer and Su8 photo-resist barrier. For the characterization of the initiator’s performance, the Photonic Doppler Velocimetry (PDV) has been taken to record its acceleration history. As it shown in the experiment result, there isn’t distinct acceleration divergence caused by the change of flyer or barrel material, the performance of parylene-C and polymide flyer with identical dimension are similar to each other.
