| titleOfInvention | Test fixture and test method for patch piezoelectric quartz device |
| abstract | The invention relates to the field of patch piezoelectric quartz device testing, in particular to a patch piezoelectric quartz device testing fixture and a testing method. A patch piezoelectric quartz device testing fixture is used in combination with a piezoelectric quartz oscillator. , including: abutment, with slide rail; self-limiting lift table, set on the slide rail, can move up and down along the slide rail and stay at any movable position; impedance matching circuit board, set on the lift table, It can establish electrical connection with the piezoelectric quartz oscillator; the external test needle is set on the lifting platform and connected with the impedance matching circuit board, which is used to detect the patch piezoelectric quartz device; the edge pressure type right-angle chuck is set in the On the base, below the test needle, it is used to quickly fix the SMD piezoelectric quartz device. From the use of active control to measure the needle to provide more convenient operation, on the basis of lifting, the external placement of the test needle is realized, which simplifies the cleaning process and difficulty of the test needle, and according to this top-down measurement The method is matched with a flexible and widely adaptable edge-pressing right-angle chuck, which further improves the adaptability and fixing efficiency of the test fixture to different shapes, and finally realizes the improvement of the test efficiency and test accuracy of the SMD piezoelectric quartz device. |
