AI Technical Summary
In existing technologies, the dispensing needles of automatic dispensing machines are prone to touching and damaging silicon photonic chips, while high-pressure gas jet dispensing cannot dispense a small amount of adhesive and is prone to splashing, resulting in contamination of the silicon photonic chips.
A tunable standing wave is generated using an acoustic wave generator. Combined with an automatic dispensing machine and image acquisition equipment, non-contact dispensing of optical adhesive is achieved. The movement of the optical adhesive is controlled by adjusting the phase and frequency of the standing wave, thus achieving precise dispensing.
This avoids damage and contamination to silicon photonic chips, enables controllability of adhesive quantity and speed, and ensures dispensing accuracy.
