Problems solved by technology

When the wafer is processed to high frequency, the thickness is only 0.03-0.1mm, and the wafers are easy to stick together. The traditional cleaning method is difficult to separate the wafer and thoroughly clean the sand in the middle, resulting in abrasive sand remaining on the wafer surface

Description

technical field [0001] The invention relates to a quartz wafer grinding and cleaning machine and a grinding and cleaning process thereof. Background technique [0002] One of the processes of quartz wafer processing is to grind the wafers to the frequency range required by customers through grinding sand. After the processing is completed, these ground wafers need to be cleaned. The cleanliness of wafer cleaning determines the accuracy of the angle sorting process. The residual sand left on the wafer during the grinding process will affect the accuracy of the wafer angle measurement, especially in some orders with high precision requirements from customers. Wafers with residual sand on the surface are likely to cause errors during angle sorting. Judgment, when it is finally processed into a quartz oscillator, it will exceed the specified frequency PPM range within the required temperature range. When the wafer is processed to high frequency, the thickness is only 0.03-0.1mm...
