Filters, as the name suggests, are devices that filter waves. "Wave" is a very broad physical concept. In the field of electronic technology, "wave" is narrowly confined to the process of describing changes in the value of various physical quantities over time.The file can be downloaded
Wafer refers to a silicon wafer used in silicon semiconductor integrated circuit manufacturing. Since it has a round shape, it is called a wafer; on the silicon wafer(fused quartz substrate), it can be processed into various circuit element structures and become an IC with a specific electrical function.The file can be downloaded
Quartz Wafers(substrate) are usually made of quartz smelted and cut and ground, with a silica content of more than 99.99%. Hardness is Mohs seven, with high temperature resistance, low coefficient of thermal expansion, thermal shock resistance and good electrical insulation properties.The file can be downloaded
