Patent number: 9500674Abstract: A probe structure includes a sleeve, a needle shaft and an elastic member. The needle shaft is accommodated in the sleeve and includes a first groove for accommodating the elastic member. The probe structure further includes a conductive component installed at the bottom of the sleeve and having an end connected into the first groove, and a second groove, so that the elastic member is situated in the first and second grooves. When the needle shaft is pressed and moved, the inner wall of the second groove is contacted with an outer sidewall of the conductive component to define a second conductive channel. With the two conductive channels, the effects of maintaining stable current transmission efficiency, reducing poor contact or disconnection, and providing good structural stability are achieved.Type: GrantFiled: February 4, 2015Date of Patent: November 22, 2016Assignee: C.C.P.

Publication number: 20080122464Abstract: A replaceable probe to be used on a test feature includes a hollow probe body to house an elastic element and at least one needle inserting in the probe body. The needle presses the elastic element and is retractable in the probe body. The probe body is surrounded by a hollow sleeve to form an anchoring relationship with the inner wall of the sleeve. The sleeve has an opening on one end to receive the needle and an open side on other end to allow the probe body to escape the sleeve. Thus when the needle is worn out after being used for a period of time, the probe body can be removed from the sleeve and test feature for replacement without disassembling the test feature. Replacement can be done quickly.Type: ApplicationFiled: August 21, 2006Publication date: May 29, 2008Inventors: Yu-Min Cheng, Wen-Ying Cheng, Min-Hsiang Sung

Publication number: 20080110304Abstract: The present invention discloses a probe clamp used for removing a damaged probe. The probe clamp includes a container, a seizing head and a push rod, and the seizing head is sheathed onto a desired removing probe. If a force is applied to drive the push rod to withdraw the seizing head, then the damaged probe can be clamped tightly for the removal. The probe clamp of the invention not only can seize the damaged probe quickly and precisely, but also can clamp and remove the probe effectively, so that the probe will not slide or touch other probes that may result in damaging more probes. Therefore, the invention improves the working efficiency and reduces the consumption of probes effectively.Type: ApplicationFiled: November 15, 2006Publication date: May 15, 2008Inventors: Yu-Min Cheng, Wen-Ying Cheng, Min-Hsiang Sung

Publication number: 20040135761Abstract: This invention uses the “row/column buffer switches” to make it possible that LCD display can scan either vertically or horizontally. This invention solved the limitation of the traditional LCD can only scan in one direction (horizontal) issue. That makes LCD will be able to accept either the landscape or the portrait images without a pre-rotate process. With the easy implementation, buffer switches can be applied to both of the two standards, STN (known as passive matrix addressing) and TFT (known as active matrix addressing) LCD devices.Type: ApplicationFiled: December 22, 2003Publication date: July 15, 2004Inventors: Yu-Min Cheng, Ming-Wu Cheng
