Product Description
Surface Acoustic Wave Piezoelectric Wafers
Piezoelectric materials convert mechanical pressure into electrical current and vice versa. When mechanical pressure is applied to these crystals, their structure deforms, creating electrical conductivity. Conversely, applying electrical current causes expansion and contraction, converting electrical energy into mechanical energy.
Manufacturing Expertise
BonTek specializes in crystal growth and wafer fabrication, with extensive experience in piezoelectric materials including Quartz Crystal, Lithium Niobate, and Lithium Tantalate. Our capabilities include producing large, thin wafers in sizes from 3" to 8" with advanced quality control equipment.
