Abstract：Low‑temperature co‑fired ceramic（LTCC）technology was employed to realize the integrated fabrication of exploding
foil initiation chip. 5 μm thick Au bridge foil（300 μm×300 μm）was prepared by screen printing，using raw porcelain sheets of
25 μm and 50 μm thickness as the flyers for the chip. Two kinds of chips with the barrel shape of circular（Φ =400 μm）and
square（L×W=300 μm×300 μm）were obtained. The electrical explosion characteristics of Au bridge foil were studied under the
discharge of 0.22 μF capacitor. The velocity characteristics of the ceramic flyer and its morphology in motion process were ana‑
lyzed by photon Doppler velocimetry. Results show that the maximum energy utilization rate of Au bridge foil at 1.8 kV，and the
final speed of flyer increases with the increase of the firing voltage. Besides，the outlet velocity of flyer in square barrel is
106-313 m ·s ，which is higher than that in circular barrel at the same firing condition. In addition，the thicker of the ceramic
-1
flyer，the more complete it will be during the course of flying. The exploding foil initiation chip prepared by the LTCC technolo‑
gy can successfully detonate the HNS explosive and ignite the BPN ignition powder. The minimum detonation voltage and mini‑
mum ignition voltage of LTCC exploding foil initiation chip（50 μm thick ceramic flyer，circular barrel）are 2.5 kV and 1.4 kV，
respectively.
