Product Description
Ultrasound Generating Piezoelectric Wafers
Piezoelectric materials generate ultrasound waves through the piezoelectric effect, where applied AC voltage causes particle vibration and pressure variations. These specialized wafers convert electrical energy into mechanical vibrations for ultrasonic applications.
Manufacturing Expertise
BonTek specializes in crystal growth and wafer fabrication with over 30 years of experience. We work with various piezoelectric materials including Quartz Crystal, Lithium Niobate, Lithium Tantalate, and specialized substrates.
Key Manufacturing Capabilities
- Large wafer fabrication: 3", 4", 6", 8" diameters conforming to SEMI standards
- Advanced equipment: Corning Flatmaster 200 Profiler, laser marking, AOI inspection
- 6-step cleaning line for superior surface quality
- Thin wafer production down to 0.08mm thickness
