Described millimeter-wave monolithic circuit chip test fixture, it is characterised in that: described tungsten copper carrier is arranged on centre slice by four M1.5 screws.
Described millimeter-wave monolithic circuit chip test fixture, it is characterised in that: the two side of described groove is respectively equipped with DC Insulator.
Described millimeter-wave monolithic circuit chip test fixture, it is characterised in that: being vertically provided with U-type groove on described end sheet, centre slice is evenly provided with several threaded holes from top to bottom, end sheet screws fastening by the screw that several run through U-type groove and threaded hole.
Described millimeter-wave monolithic circuit chip test fixture, it is characterised in that: described screw adopts M3.0 screw.
The utility model has the advantages that:
The utility model have employed miniaturization Design as far as possible, can easily adapt to monolithic integrated microwave circuit test environment complicated and changeable, it is possible to the outspoken speed test of desirable reply monolithic multiterminal; In monolithic integrated microwave circuit high frequency is tested, it is that Designers well researches and develops instrument; And junctor and radio frequency needle can be changed flexibly according to negative and positive head if any abrasion in the middle of routine use, thus reduce testing cost, it is to increase test accuracy and reliability.
Adopt fixture of the present utility model, before and after test accuracy and reliability test, monolithic integrated circuit chip can be carried out direct current parameter testing, microwave index test, there is precision height, compatible good, excellent heat dissipation performance, operating frequency height, it may also be useful to the features such as convenience.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The assembling schematic diagram of sheet centered by Fig. 2.
Embodiment
As shown in Figure 1, 2, millimeter-wave monolithic circuit chip test fixture, include a centre slice 1, two end sheets 2, the top of centre slice 1 has groove, the two side of groove is respectively equipped with DC Insulator 3, being provided with tungsten copper carrier 4 by four M1.5 screws 6 in groove, monolithic microwave chip 5 to be measured sinters on tungsten copper carrier 4, tungsten copper carrier 4 is positioned at monolithic microwave chip 5 two ends and is also respectively equipped with micro-band transmission line 7; The outer side of described end sheet 2 is respectively equipped with radio frequency junctor 8, and the interior side of end sheet 2 is respectively equipped with probe 9; Described two end sheets 2 are clamped on centre slice 1 and probe 9 on two end sheets 2 fits tightly in the end of two micro-band transmission lines 7.
Vertically being provided with U-type groove 10 on end sheet 2, centre slice 1 is evenly provided with several threaded holes 11 from top to bottom, end sheet 2 screws fastening by the M3.0 screw 12 that several run through U-type groove 10 and threaded hole 11.
Turn and join test process:
1, first the tungsten copper carrier sintering chip is arranged on centre slice with four M1.5 screws;
2, the end sheet on both sides is fixed on centre slice by M3.0 screw, during installation, should be noted that end sheet probe accurately fits tightly at microstrip line surface metal;
3, DC Insulator pin is connected to chip power supply port, it is provided that corresponding biased condition;
4, connect relevant equipment, start test.
The utility model is particularly useful for monolithic integrated microwave circuit debugging, time in its test process as needed to change different product, only needing to unclamp the end sheet screw at two ends, four screws of immobilization carrier unload just easily can be changed variant production easily and start test assignment fast.
