With best regards, Brian Ko / President of TOP TECH ELECTRONICS
Looking forward to getting your requirements.
We are working for crystal indurstry for over 16 years. At least we know how to make the
crystal parts to vibrate at the so stable condition. Your sample is enough for us to evaluate
and analysis. Your contacting and touch are always so welcomed.
We can offer you the monitory crystal (so called, thickness sensors) at the resonable price.
This is the sensor to control the thickness at vacuum. The frequency goes down along its thickness is bigger to bigger. |
