Responding to highly precise frequency adjustment and shape processing.

Etching (Wet, Dry, Blast)


Etching is a technology for processing materials by using the corrosive action of chemicals, etc.

Combining it with photolithography technology enables the formation of a large number of tuning fork or AT-cut crystal units that are compact and have good external dimension accuracy, from crystal blank plate in a batch. This combination can also be used for thickness adjustment to adjust the frequency of AT-cut crystal blanks.

Along with the increasing miniaturization of electronic devices, crystal units are also being made increasingly compact, and this is an essential technology for realizing the small-scale, high-accuracy processing that is difficult to achieve by machining.
