Ultrasonic welding is an industrial technique whereby high-frequency ultrasonic acoustic vibrations are locally applied to workpieces being held together under pressure to create a solid-state weld.
There are different joints in ultrasonic welding; Butt Joint, Step Joint, Tongue and Groove Joint, Shear Joint and Scarf Joint
We could fully encapsulate of PCBA or components from dust & water, hence meeting highest IP rating on product requirement.
During the molding process, mold-set are relatively cold which help to decrease the temperature of melted resin without damaging the PCBA or component.
This process is widely used not only for wearable & non tampering devices.
