The difference between them is that special tweezers are used to clamp the part and hold it before pulling the part. Tweezer pull testing is used to perform pull tests on wires, ribbons, pins, balls or components. It is important that the part that is tested is not dislocated when the tweezer is closed.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">For a standard wire pull test the hook applies the force by pulling the wire. The applied force on the wire is not equal to the force applied to the ball or wedge, because the force is not applied exactly above this ball or wedge. With a tweezer pull test it is possible to apply the force directly above the ball or wedge. The measured force will equal the applied force. Before performing this test, it may be necessary to cut the wires first. This can be done with special tips that can cut the wire. It is also possible to shear the bond on one side, straighten the wire with the tweezer and then perform the test.<\/span><\/p>\n<p><span data-preserver-spaces=\"true\">Xyztec offers the\u00a0<\/span><a class=\"_e75a791d-denali-editor-page-rtfLink\" href=\"https:\/\/www.xyztec.com\/usb-tweezers\/tweezers\/\" target=\"_blank\" rel=\"noopener noreferrer\"><span data-preserver-spaces=\"true\">USB tweezer<\/span><\/a><span data-preserver-spaces=\"true\">\u00a0as a general solution for most tweezer pull tests.
