Embodiment Construction

[0039] Such as Figure 1 to Figure 3 Shown is the structure of the existing single solder ball impact tester.

[0040] The single solder ball impact tester of the present invention utilizes the original alignment system XYZ workbench 610 made up of adjustment devices 611, 612, 613, and the XYZ table 610 made up of support members 621, impact heads 623, motors 625 and clutches 627. impact system; and a sampling platform 640 including a fixture 641; a detection system 630 including a solder ball position image monitor; the sampling platform 640 is fixed on the vertical vertical plate of the XYZ worktable adjustment device 613 and extends horizontally.

[0041] Such as Figure 4 to Figure 10 As shown, the single solder ball welding shear strength impact tester of the present invention includes an alignment system, an impact system, and a sampling platform system. The alignment system includes an XYZ workbench, and the XYZ workbench is composed of X, Y, and Z adjustment devices T...

Abstract

The invention discloses an impact tester of a single soldered ball, which comprises an alignment system, an impact system and a sampling platform system, wherein the alignment system comprises an XYZ working table, and a sampling platform is fixed on the XYZ working table and stretches outwards horizontally; and a supporting frame of the impact system is provided with a probe-type distance measure sensor through a support. The impact tester can ensure that the whole testing process is conveniently and accurately monitored and analyzed and the application type of an original instrument is greatly enhanced. The impact tester can surely guarantee the accuracy of a starting condition; an optimized device can ensure that a tested component is completely horizontal and fixed; and an accurate sensor is used for conveniently positioning the impact height. Besides, automatic system control is also applied to an improved instrument. A computer data acquisition card is used for performing real-time monitoring and data acquisition on the complete testing process, and performing feedback regulation on a test condition according to a result, so the operating process is simple, convenient and accurate, and the computer data acquisition card is greatly favorable for carrying out an acquisition test.

Description

technical field [0001] The invention relates to a test instrument, in particular to a single ball welding anti-shear strength impact tester. Background technique [0002] The ball array is widely used in electronic packaging technology, and the packaging strength between the ball array and the substrate is one of the basic standards generally recognized by the industry. Previously, to test this strength, the industry generally used a single solder ball shear test to obtain reliable solder ball attachment strength results. However, due to the fact that the low-rate shear test cannot predict the high-strain-rate impact under real conditions, it was later developed into a single-ball impact tester, which has been widely recognized for its high-speed and accurate test results. [0003] Existing single solder ball impact tester, such as the Chinese invention patent application "Single Solder Ball Impact Tester" published on June 10, 2009 in the Chinese Invention Patent Bulletin,...
