Megahertz ultra-high frequency ultrasound (also known as megasonic) has been verified and widely used in various semiconductor manufacturing processes, such as cleaning, chemical mechanical polishing, development, etching, lift-off, etc. with its extremely low cavitation effect and fine cavitation bubbles. Therefore, megasonic cleaning transducer and system have become one of the key components in semiconductor chip manufacturing equipment.

Recently, a Siansonic new ultrasonic coating system for drug eluting balloon and peripheral stent, passed the tests by customers in the implantable medical devices industry. This ultrasonic coating system is mainly used for depositing drug layer on multiple balloons or peripheral stents.

Recently, Siansonic first ultrasonic spray coating system for volume production of membrane electrodes of proton exchange membrane fuel cells was successfully delivered. This equipment is equipped with double automatic in and out vacuum heating platform for the first time, which can facilitate the loading and unloading of proton exchange membrane in the production process, and realize the uninterrupted spraying of catalyst through alternating loading and unloading, so as to improve the production efficiency of membrane electrode.
