Description

Automatic test system for electrical property of porcelain piece

Technical Field

The utility model belongs to the technical field of electrical property testing, and particularly relates to an automatic testing system for electrical property of a porcelain piece.

Background

In recent years, the integrated circuit technology is rapidly developed, the metal-ceramic packaging form is widely applied, and the ceramic piece is just a semi-finished product of a ceramic packaging product. The electrical property is an important process inspection item, and the performance guarantee and the production efficiency of the ceramic packaging product are directly influenced by the method for testing the electrical property of the ceramic piece (conduction test, insulation test and capacitance test).

At present, the electrical performance test methods mainly comprise manual test and flying probe test. The manual test method adopts an electrical property tester, and two meter pens are held by hands under a microscope to touch a position to be tested at the same time for testing, so that the manual test method has the following defects: (1) the gauge pen is difficult to touch the metallized pattern accurately, and the test difficulty is high. (2) And the test items are detected one by one, so that the working efficiency is low. (3) Eyes and hands can work at high intensity at the same time, and the fatigue strength is high. And (4) the manual test is easy to miss items, and the miss test risk is large. The flying probe testing method is a semi-automatic testing method and has the following defects: (1) the porcelain piece is manually placed on the fixing tool according to the direction for testing, and the working efficiency is low. (2) After the test is finished, the device displays qualified products and unqualified products, and the qualified products and the unqualified products are taken down manually according to prompts, so that the test efficiency is low. (3) It is expensive.

Among the two common testing methods are that the probe contacts the position to be tested and then tests are performed. However, in the actual testing process, the phenomenon that the probe does not contact the bonding pad and the insulation test is qualified is easy to occur, so that the test leakage and the defective product flow out are caused, and no effective fool-proof measure is provided.
