Abstract

The invention relates to a shearing force testing tool. The testing tool comprises a supporting seat assembly, a clamp assembly and a testing head assembly, wherein a linear slide rail in the supporting seat assembly is fixedly mounted on a supporting plate; in the clamp assembly, a bottom plate is in sliding connection with the linear sliding rail, a cover plate is detachably connected with the bottom plate, and a test hole matched with a test convex point is formed in the cover plate; in the testing head assembly, one end of a fixing frame is fixedly connected with the supporting plate, a push rod penetrates through the other end of the fixing frame and is perpendicular to the linear sliding rail, and a push head is perpendicular to the plane where the cover plate is located and telescopically inserted into the push rod. The device is simple in structure, convenient to operate and stable in testing.

Description

technical field [0001] The invention relates to the technical field of component reliability testing, in particular to a tool for testing shear force. Background technique [0002] The electronic components soldered on the circuit board will cause mechanical stress on the solder joints due to shocks such as vibrations generated under welding, transportation, and use conditions, and eventually lead to solder joints or device failure. The shear force test can reflect the bond between the pad and the welding metal. Bond strength. Therefore, the solder joint shear test is an important reliability test for solder joints and components on the circuit board pad. [0003] Tensile shear tester is a common testing instrument used in the industry to evaluate the soldering strength of BGA solder joints. Under the current test requirements, the test cost is high, and it needs to be adjusted again before testing different solder joints or components, and the test is unstable. The operat...
