Push-pull force testing device for laminated packaging

[0043] refer to figure 1 , the push-pull force testing device comprises a base 1, one end of the upper side of the base 1 is fixedly connected with a frame 2, and a push-pull force gauge 21 is slidably connected to the frame 2 along the vertical direction, and the inside of the frame 2 is arranged to drive the push-pull force gauge 21 to lift A lifting device, a test needle 22 is fixedly connected to the side of the push-pull force gauge 21 facing the base 1 .

[0044] The other end on the upper side of the base 1 is provided with a workbench 3 , and a moving mechanism 4 connecting the two is provided between the base 1 and the workbench 3 . The moving mechanism 4 includes a first moving assembly 41 that moves along the Y-axis direction and a second moving assembly 42 that moves along the X-axis direction. Chips to be inspected are placed on the workbench 3 , wherein the chips are made by a package-on-package process.

[0045] refer to figure 1 and figure 2 , the first moving

[0066] refer to Figure 9 and Figure 10 , the difference from Embodiment 1 is that a support assembly 31 for supporting and stabilizing the chip is provided between the workbench 3 and the pressing plate 5, the support assembly 31 includes a support block 311 parallel to the moving direction of the chip, one end of the support block 311 is connected to the working Table 3 is fixedly connected, and the other end is facing the pressing plate 5, and one end of the supporting block 311 facing the pressing plate 5 is connected with a number of supporting wheels 312 distributed along the length direction of the supporting block 311, and the circumference of the supporting wheel 312 is fixed with a number of evenly distributed suction cups 313 , the suction cup 313 on the side of the support wheel 312 close to the platen 5 presses against and adsorbs on the side wall of the chip.

[0067] When the chip moved in translation between the workbench 3 and the pressing plate 5, the suction
