Embodiment
Below illustrate in detail by the specific embodiment conjunction with figs., with the effect that is easier to understand the purpose of this utility model, technology contents, characteristics and is reached.
As shown in Figures 1 and 2, a supporting bracket 10 is arranged on the load board 12, and this load board 12 is provided with two switching bases 14, and its surface is formed with pin hole 40; Has a fluting 16 on the supporting bracket 10, the inward flange of fluting 16 is equipped with a fixed frame 18, for a fish plate 20 is set, on fish plate 20 and cooperate two the switching bases 14 positions be formed with two place's openings 22, the relative dual side-edge of fish plate 20 has a guide plate (guiding pin) 26 respectively, be arranged on the classifier with guide engagement plate 20, the inward flange of this two opening 22 is equipped with a protruding fishplate bar 24, two seat cover assemblies 28 can be locked on this protruding fishplate bar 24, as shown in Figure 3, each seat cover assembly 28 is made up of a flap 30 and an IC pedestal 32, these flap 30 central authorities are formed with a flap opening 34,32 pairs of this IC pedestals should flap opening 34 after, nationality is locked in IC pedestal 32 on the flap 30 by four screws 60; When IC pedestal 32 is fastened in flap opening 34, the pin 36 on IC pedestal 32 surfaces can expose, and contact with the pin of semiconductor device to be measured, it is tested, relative two sides on the surface of flap 30 are respectively equipped with a guide post 38, so that the probe 41 of IC pedestal 32 belows is inserted in the pin hole 40 of switching base 14 smoothly.
Above-mentioned supporting bracket 10 with fluting 16 and fixed frame 18, can make whole fish plate 20 firm being arranged on this supporting bracket 10, and can not hide the switching base 14 on the load board 12, the setting of this fish plate 20 has bigger contact area, so steadiness is higher; On the other hand, because IC pedestal 32 is arranged on the fish plate 20 by flap 30, and fish plate 20 is locked in the middle fluting 16 of supporting bracket 10, therefore the IC pedestal 32 in this seat cover assembly 28 is that the plane with supporting bracket 10 is a horizontal reference, be inserted in the pin hole 40 of switching base 14, when therefore tilting as if switching base 14, only can make IC pedestal 32 belows probe 41 plug deep mixed, and IC pedestal 32 still can be parallel with classifier, when then the following depressor of classifier is pressed into IC pedestal 32 to semiconductor device to be measured for being pressed into uniformly, the pin of semiconductor device contacts well with the pin 36 of IC pedestal 32, thereby can get a rational test result.
Wherein, the bottom surface of above-mentioned supporting bracket 10 is formed with a depressed part (not shown), and the circuit that can differ at number on the load board 12 provides bigger accommodation space; And supporting bracket 10 bottom surfaces have a sticking material 42, it is a non-conductive material, can avoid 12 of supporting bracket 10 and load board to produce short circuit phenomenon because of improper the contact, periphery in the bottom surface of this sticking material 42 has a bed hedgehopping sheet 44, and the circuit accommodation space of 12 of this supporting bracket 10 and load board is more enlarged.
Wherein, as Fig. 2 and shown in Figure 4, four corners, periphery of two flaps 30 of above-mentioned seat cover assembly 28 evenly are formed with eight perforation 46, this eight perforation 46 also is respectively equipped with eight jacks 48 relatively on protruding fishplate bar 24, one length is passed perforation 46 and jack 48 greater than the screw 52 of flap 30 thickness, two flaps 30 are locked in respectively on the protruding fishplate bar 24 of this two opening 22, make it the location; Each perforation 46 other screw 50 that are formed with respectively at flap 30.
When desire is picked up seat cover assembly 28, as Fig. 5 and shown in Figure 6, the screw 52 that earlier all is inserted in perforation 46 and the jack 48 takes out, again screw 52 is screwed in the screw 50 of this flap 30, because the length of this screw 52 is greater than the thickness of these flap 30 screws 50, therefore along with screw 52 screw-in screw 50 slowly, screw 52 can push up protruding fishplate bar 24, along with lasting rotary screw 52, then seat cover assembly 28 can be by the top from this fish plate 20, and when changing IC pedestal 32 in the seat cover assembly 28, the probe 41 of its below can very easily break away from the pin hole 40 of the base 14 of transferring, and be difficult for to cause the damage or the bending of probe 41 40 supports of pin hole greatly.
Fig. 7 is an embodiment of the present utility model, and consults Fig. 1 simultaneously, and load board 12 is arranged on the measuring head of a tester table 56, and two group categories machines 54 have been set up in the measuring head top, and it is corresponding mutually with the supporting bracket 10 on the load board 12; Be arranged at the fish plate 20 in the fluting 16 of supporting bracket 10, and be located at corresponding two following depressors of being located on the classifier 54 58 of two seat cover assemblies 28 on the fish plate 20, so that semiconductor device to be measured is pressed on the IC pedestal 32 by following depressor 58, probe 41 via IC pedestal 32 belows imports the pin of signal from semiconductor device to be measured on the load board 12, and by load board 12 belows connection measuring head, with as the two-way communication bridge between tester table 56 and semiconductor device to be measured, after test is finished, by the robotic arm on the classifier 54 part is placed on the different part dishes by different test results again.
Only the above is a specific embodiment of the utility model only, is not to be used for limiting the scope that the utility model is implemented.So be that all equalizations of doing according to the utility model claim change and modification, all should be included in the claim of the present utility model.
