Abstract
The utility model relates to a special fixture for flying probe testing of a high-density interconnection circuit board. The special fixture comprises a bottom plate, a circuit board outer frame and multiple clamping devices, wherein the circuit board outer frame is arranged on the upper surface of the bottom plate, the multiple clamping devices are uniformly arranged on the bottom plate on the outer side of the circuit board outer frame, each clamping device comprises an upright, a rotating beam and a pressing plate, the rotating beam is hinged on the upper end of the upright, the rear end of the rotating beam is provided with a screw rod used for fixing the rotating beam and the upright in a penetrating manner, and the lower ends of the locking screw rods arranged on the front ends of the rotating beams positioned on the same side of the circuit board outer frame are jointly connected with the upper ends of the pressing plates arranged on the same sides with the rotating beams. According to the special fixture, a circuit board is placed in the circuit board outer frame arranged on the bottom plate, and is pressed and fixed through the clamping devices uniformly arranged on the bottom plate on the outer side of the circuit board outer frame, then the bottom plate is clamped in a flying probe tester, when a flying probe touches the bottom plate, the bottom plate upwards supports the circuit board without generating the problem of bending the circuit board due to stress; and elastic cushions arranged on the bottom surfaces of the pressing plates can not abrade the appearance of the circuit board, thus the special fixture is very safe.
Description
Technical field
The utility model belongs to high density interconnected circuit plate manufacturing technology field, especially a kind of high density interconnected circuit plate flying probe unit clamp.
Background technology
The circuit board manufacturing need be tested it after accomplishing, and conventional test methods is to accomplish through needle-bar test machine testing jig, but the manufacturing cost of this testing jig is higher, testing and measuring technology is complicated.People have invented flying probe tester through research for this reason, and it is controlled by predefined program; A plurality of probe contact pads and via hole, thereby the element test of completion circuit board, but in test process; Probe needs to contact firmly with circuit board, and circuit board is had certain impulsive force, impacts the injury that circuit board is caused in order to reduce probe; People have invented probe " soft landing " way of contact, but Ren Ranhui is when producing the less circuit board testing of certain impulsive force, especially thickness; Faults such as sheet, tabs very easily occur falling, cause test normally to accomplish, and increased test period.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of high density interconnected circuit plate flying probe unit clamp rational in infrastructure, easy to use is provided.
The technical scheme that the utility model is taked is:
A kind of high density interconnected circuit plate flying probe unit clamp; It is characterized in that: comprise base plate, circuit board housing, clamp device; The circuit board housing is installed in the upper surface of base plate; On the base plate in the circuit board housing outside, be uniformly distributed with a plurality of clamp devices are installed, said clamp device comprises column, rotating beam and pressing plate, and the rotating beam hinge is contained in the upper end of column; Install one in the rotating beam rear end and be used for rotating beam and the fixing screw rod of column, the lower end that is positioned at the tie down screw that the rotating beam front end of the same side of circuit board housing adorned connects the upper surface of the pressing plate that homonymy is provided with jointly.
And the lower surface of said pressing plate is equipped with cushion.
The advantage and the good effect of the utility model are:
In the utility model, in the circuit board housing that circuit board is placed on the base plate to be adorned, and clamp device is installed is fixed through being uniformly distributed with on the base plate of the circuit board housing outside; Then base plate is clamped in the flying probe tester; In probe when touching,, the problem of the stressed bending of circuit board can not appear in the base plate support circuit plate that makes progress; And the cushion that install the pressing plate bottom surface can be to the apparent generation wearing and tearing of circuit board, safety very.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with embodiment, the utility model is further specified, following embodiment is illustrative, is not determinate, can not limit the protection domain of the utility model with following embodiment.
A kind of high density interconnected circuit plate flying probe unit clamp; Shown in Fig. 1～2; The innovation of the utility model is: comprise base plate 10, circuit board housing 4, clamp device, the circuit board housing is installed in the upper surface of base plate, and the space in it is used to place circuit board 5; On the base plate in the circuit board housing outside, be uniformly distributed with a plurality of clamp devices are installed; Said clamp device comprises column 3, rotating beam 2 and pressing plate 6, and rotating beam cuts with scissors the upper end that is contained in column through hinge 8, installs one in the rotating beam rear end and is used for rotating beam and the fixing screw rod 7 of column; The screw rod lower end engages after connecting the made screw of column upper end phase contraposition is fixed rotating beam and column, and the lower end that is positioned at the tie down screw 1 that the rotating beam front end of the same side of circuit board housing adorned connects the upper surface of the pressing plate of homonymy setting jointly.
For fear of the wearing and tearing of pressing plate, cushion 9 is installed in the bottom surface of pressing plate to circuit board surface.
In the present embodiment, on the base plate in each side outside of circuit board housing two covers are installed all and clamp device, installation is more certainly can realize the even clamping to circuit board, but certainly will increase the complicacy of operation, so two covers are for preferred.
When the utility model used, operating personnel at first unscrewed the screw rod and the rotating beam that overturns, and then circuit board are placed in the circuit board housing; Rotating beam again overturns; Tighten screw rod, tie down screw is being tightened, make pressing plate tight, firm being pressed in the circuit board housing of circuit board; At last base plate is clamped in the flying probe tester, starts flying probe tester and accomplish test.When probe was touched, the base plate support circuit plate that makes progress the problem of the stressed bending of circuit board can not occur, and the cushion that install the pressing plate bottom surface can be to the apparent generation wearing and tearing of circuit board, safety very.
Claims (2)
1. high density interconnected circuit plate flying probe unit clamp; It is characterized in that: comprise base plate, circuit board housing, clamp device; The circuit board housing is installed in the upper surface of base plate; On the base plate in the circuit board housing outside, be uniformly distributed with a plurality of clamp devices are installed, said clamp device comprises column, rotating beam and pressing plate, and the rotating beam hinge is contained in the upper end of column; Install one in the rotating beam rear end and be used for rotating beam and the fixing screw rod of column, the lower end that is positioned at the tie down screw that the rotating beam front end of the same side of circuit board housing adorned connects the upper surface of the pressing plate that homonymy is provided with jointly.
