Based on MEMS technology, this paper realized the chip preparation of the synchronous initiation array and obtained the ideal process parameters. The MEMS multi-point exploding metal foil synchronous array chip replaces the traditional initiation array composed of electric detonators, and has a greatly reduced volume and could be prepared in batches. By testing the electrical explosion parameters of the array chip, the peak voltage, peak current, peak time and other data of different ignition voltages are obtained. At the same time, we proposed a method to test the synchronization of the array using multi-channel photonic doppler velocimetry, and obtained the synchronization data when the firing voltage was 2500 V and 2800 V, which provided help for the subsequent optimization design.
