Description

Surface mount integrated circuit pin coplanarity test platform
Technical field
The utility model relates to test platform, specifically surface mount integrated circuit pin coplanarity test platform.
Background technology
Surface mount integrated circuit (SMIC) is applied to practice widely, lead coplanarity is the important component part of SMIC outline dimension standard, this index carries out hand inspection by the operator on production line usually, its result affects greatly by artificial subjective factor, the not high and labor expense of accuracy.Existing automatic detection system error is little, but need use High-precision standard block and through strict calibration, not only use loaded down with trivial details, calibration result also directly affects accuracy of detection, and in addition, when sample and pedestal relative position change, test result is by inaccurate.Therefore, design that structure is simple, easy to use, precision is high and the surface mount integrated circuit pin coplanarity test platform do not affected by reference data calibration result is very necessary.
Summary of the invention
The purpose of this utility model is to provide that a kind of structure is simple, easy to use, precision is high and not by the surface mount integrated circuit pin coplanarity test platform that reference data calibration result affects.
For achieving the above object, the utility model adopts following technical scheme:
Surface mount integrated circuit pin coplanarity test platform, comprise pedestal and be arranged on the backlight on pedestal, it is characterized in that reference data pedestal being also provided with outside backlight square tubular, backlight is provided with high transparent glass workseat, the high upper surface of transparent glass workseat and the upper surface of reference data are positioned at same level, on pedestal, outside reference data, surrounding is respectively arranged with high-precision optical glass mirror, high-precision optical glass mirror is that upper base is greater than go to the bottom trapezoidal, angle on high-precision optical glass mirror and pedestal between plane is 45 °, the minute surface of high-precision optical glass mirror inwardly.
Further, the deviations from planarity of described high transparent glass workseat is not more than 2 μm, and described high-precision optical glass mirror is isosceles trapezoid, and adjacent high precision optical glass reflective mirror is connected to each other by its side.
Adopt the utility model, can cost of labor be reduced and directly test SMIC lead coplanarity without the need to using calibrated bolck to demarcate reference data plane.The utility model structure is simple, easy to use, precision is high.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to cut-open view;
Fig. 4 is the schematic diagram after the utility model puts SMIC.
In figure: 1-pedestal; 2-backlight; 3-reference data; 4-height transparent glass workseat; 5-high-precision optical glass mirror; The reflected image of 6-reference data in high-precision optical glass mirror; 7-SMIC; The reflected image of 8-SMIC in high-precision optical glass mirror.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Surface mount integrated circuit pin coplanarity test platform shown in figure, the backlight 2 comprising pedestal 1 and be arranged on pedestal 1, pedestal 1 is also provided with outside backlight 2 reference data 3 of square tubular, backlight 2 is provided with high transparent glass workseat 4, the upper surface of high transparent glass workseat 4 and the upper surface of reference data 3 are positioned at same level, on pedestal 1, outside reference data 3, surrounding is respectively arranged with high-precision optical glass mirror 5, it is trapezoidal that high-precision optical glass mirror 5 is gone to the bottom for upper base is greater than, angle on high-precision optical glass mirror 5 and pedestal 1 between plane is 45 °, the minute surface of high-precision optical glass mirror 5 inwardly.
Preferred embodiment is: in such scheme, and the deviations from planarity of described high transparent glass workseat 4 is not more than 2 μm, and described high-precision optical glass mirror 5 is isosceles trapezoid, and adjacent high precision optical glass reflective mirror 5 is connected to each other by its side.
During the work of this device, first SMIC7 pin is placed on downwards on high transparent glass workseat 4, then with the reflected image 8 of SMIC and the reflected image 6 of reference data 3 in industrial camera shooting high-precision optical glass mirror 5, then above-mentioned image is passed to computing machine.
The content be not described in detail in this instructions, belongs to the known prior art of those skilled in the art.
