Abstract
Description
Technical Field
[0001] This application relates to a cleaning line and its method, particularly an automatic test socket cleaning line and its method. Background Art
[0002] In recent years, with the continuous maturity and development of semiconductor manufacturing technologies, various high-performance electronic products have been continuously introduced. The functions of electronic products are developing towards user-friendliness and multi-functionality, and there are various integrated circuit (IC) components with different functions and packaging forms inside electronic products. However, regardless of the packaging form, the integrated circuit components are disposed on relevant carrier boards (such as L / F, organic core substrates, coreless substrates, etc.), and must undergo electrical function tests of the packaging structure before leaving the factory to ensure the normal electrical functions of the packaged products.
[0003] Existing electrical test equipment places a device under test between an upper cover and a test socket, and uses a pneumatic bonding method to closely fit the upper cover, the test socket, and the device under test. The probes on the upper cover are electrically connected to the electrical contact points on the upper side of the device under test, and the probes on the test socket are electrically connected to the electrical contact points on the lower side of the device under test. After long-term use of the test socket, due to contact and extrusion with the device under test, dirt and residues will remain on the test socket, which will cause test errors or inability to perform tests, and there is a risk of damaging the device under test. Therefore, the industry will regularly perform test socket cleaning operations after using for a period of time to avoid the above problems.
[0004] However, since the test socket is for testing different packaging structures, there are different forms of test sockets, and their cleaning methods will also be different. After the test socket is removed from the electrical test equipment, it is necessary to first perform a manual judgment of the test socket type to determine which cleaning process to follow.
