Abstract
Description
Technical Field
[0001] The utility model belongs to the field of communications, and particularly relates to an improved structure of a chip patch thrust test pusher with the advantages of accurate testing, easy use, and no damage to products. Background Art
[0002] After the chip is attached to the tube holder, its firmness needs to be tested. A digital display thrust test bench is required. A push knife is installed on the test bench. The value of the push knife pushing the chip is displayed on the digital display. This way, the thrust can be tested. At present, the test push knife structures currently used are as follows. Figure 2 As shown, the front end is a blade and the rear end is a cylindrical handle. This structure can meet certain usage requirements, but it also has a major defect. During testing, the area behind the blade will contact and rub against the pins of the tube holder, which will damage the pins, resulting in a low product yield and affecting the test accuracy, making it impossible to effectively meet usage requirements.
[0003] The technical problem to be solved by the utility model is to provide an improved structure of a chip placement thrust test pusher with high testing accuracy, easy use, no damage to products, high yield rate and effective satisfaction of use requirements. Utility Model Content
[0004] In order to solve the problems of the above-mentioned prior art in which the rear area of the blade contacts and rubs with the pins of the tube holder, easily damaging the pins, having a low product yield, affecting test accuracy, and failing to effectively meet usage requirements, the present invention adopts the following technical solutions:
[0005] The utility model provides an improved push knife structure for chip patch thrust testing, comprising a knife body, the tail of which is inserted and fixed on an external digital display thrust testing machine, the front end of the knife body being a V-shaped pointed blade, and a hollow area for facilitating making way being provided at the rear of the pointed blade, wherein the hollow area has a length of 1.5 mm and a width of 0.6 mm.
[0006] The beneficial effects of the utility model are: the hollow shape of the rear part of the blade is convenient for making way, will not contact the friction pins, has high test accuracy, is easy to use, does not damage the product, has a high yield rate, and effectively meets the use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 This is a structural diagram of an embodiment of the present utility model.
[0008] Figure 2 This is a schematic diagram of the traditional structure. DETAILED DESCRIPTION
[0009] The preferred embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0010] See also Figure 1, an improved push knife structure for chip patch thrust test, including a knife body 1, the tail of the knife body 1 is inserted and fixed on an external digital display thrust tester, the front end of the knife body 1 is a V-shaped pointed blade 11, when the knife body is pushed forward, the pointed blade directly contacts the chip patch, increasing the thrust to test its maximum thrust value, and a hollow area 12 is provided at the rear of the pointed blade 11 for easy clearance, the hollow area 12 is 1.5mm long and 0.6mm wide, and the hollow structure can effectively make way during the test, and the knife body will not contact the friction pin, which will not affect the test effect, the test accuracy is high, and the product will not be damaged. The push knife is also more convenient to move back and forth, and it is simple to use and operate.
[0011] The beneficial effects of the utility model are: the hollow shape of the rear part of the blade is convenient for making way, will not contact the friction pins, has high test accuracy, is easy to use, does not damage the product, has a high yield rate, and effectively meets the use requirements.
[0012] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
