In He Shuai company, we did 100% testing report for every piece. No matter what you placed it order with 1 pcs or hundreds thousands. Making sure of that every products are 100% high quality. Then,our QC department is getting more important in this production processing. How can we test it?
- Machine: Impedance Analyzer
- We first calibrate analyzer by open-short and 50 Ohl load in related frequency range. Then we’ve made automatic measurements of IZI, Teta, Conductance, Reactance, Susceptance etc. We’ve found resonace frequecies and draw smith chart etc…
- For example: 2Mhz, HIFU piezo ceramic
We need adjust the machine frequency from 1.5Mhz to 3Mhz.
That’s very important setting. Don’t set it wrong ways. Like : 1Mhz to 2Mhz.
Or 2Mhz to 3Mhz. Make sure your frequency is within your setting range.
See the picture as below:

The bundle includes a Piezoelectric Displacement Sensor, Heated Piezoelectric/Pyroelectric Measurement Test Fixture, and Advanced Piezoelectric Software. The Bulk Piezoelectric/Pyroelectric Test Bundle allows samples to internally be heated to 230C in a self-contained test fixture. The heating unit is built-in to the sample holder, so no additional temperature chamber is necessary. The bundle’s simple user interface is controlled by Radiant’s fully automated Vision Data Acquisition Software
- the Bulk Piezoelectric Test Bundle is a cost effective option for researchers measuring piezoelectric displacements on the order of one micron or larger using Radiant testers. The high voltage displacement test fixture provides a safe operating environment for testing at high voltages and is rated to 10kV. The fiber optic sensor detects the amplitude of non-coherent light reflected from the sample surface to determine the distance from the sensor wand to the sample surface.
