Technical field

The utility model relates to a kind of electric performance test equipment of semiconductor devices, especially relates to a kind of ICT measurement jig.

Background technology

In the time of in the manufacturing process of printed circuit board (PCB), need test (PCB Online testing) tool by ICT it is carried out on-line testing.For ICT measurement jig with compound dials, because compound dials one surface is provided with probe, another surface needs connection cable, existing tool is installed generally at fixedly connected device such as cushion block being set and constituting syndeton of compound dials, this syndeton structure is complicated, and be easy to make compound dials joint face to produce microdeformation, and influence the sliding capability of the probe on it, thereby reduced the reliability of tool.

Summary of the invention

The utility model fundamental purpose provides a kind of simple in structure, ICT measurement jig that reliability is higher.

Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of ICT measurement jig, comprise frame, be built-in with the end box of test control system, compound dials and support plate, compound dials and support plate are provided with the probe corresponding with pcb board to be tested, test control system is circumscribed with display device, it is characterized in that: described frame is provided with cylinder, the some guide pillars that be arranged in parallel, and can actuating down and the portable plate that slides up and down of being provided with on the guide pillar at cylinder, the portable plate middle part is provided with U type groove, compound dials is fixed on the U type trough rim frame of portable plate, and support plate is located at compound dials below.For the stationarity of guarantee sliding and improve bearing accuracy, guide pillar is made as fourth officer, and four jiaos of portable plates are placed in; During use, pcb board to be tested is placed on the support plate, cylinder presses down, and compound dials is fastened on the pcb board to be tested, begins to carry out the test of projects thereafter.This structure, simple in structure, easy operating can be realized the robotization tested, the on-line testing when being fit to small-sized pcb board and producing in batches.The portable plate middle part is provided with the U type groove structure, the compound dials middle part corresponding with U type groove exposed, can make things convenient for compound dials connection cable, in addition, because the surface of compound dials abuts on the portable plate, so be difficult for producing distortion, can guarantee the sliding capability of probe effectively, thereby improve the reliability of tool.

In order to improve security, as preferably, the base plate that the top board of frame, lower end are fixed in frame is fixed in the upper end of described guide pillar; Be arranged with spring on the guide pillar, this spring is between the base plate of portable plate and frame.The top board of frame, the structure of base plate that frame is fixed in the lower end are fixed in the upper end of guide pillar, are convenient to the adjustment of the depth of parallelism between guide pillar.The setting of spring can be played the effect of damping, buffering, makes composite pin plate near test plate (panel) to be measured the time, portable plate is applied certain resistance its speed of pressing down is slowed down, and avoids the cylinder excessive velocities that test board is formed and impacts.

For improving the dirigibility that heating plate moves, as preferably, be fixed with sliding sleeve on the described portable plate, sliding sleeve is enclosed within on the guide pillar slidably.Sliding sleeve slides steadily portable plate, and improves the bearing accuracy of portable plate.

Owing to be on-line testing, high more helping more of automaticity enhances productivity, and as preferably, the base plate of described support plate or frame is provided with test plate (panel) to be measured inductive switch that triggers in place on support plate.During work, when test plate (panel) to be measured after in place on the support plate, can trigger inductive switch, inductive switch sends signal and gives control system, control system starts the relevant gas path control valve of cylinder, and cylinder is pressed down automatically.

Automatically enter testing process after cylinder presses down, can enhance productivity further, as preferably, described compound dials or frame or portable plate are provided with the position switch that detects compound dials downstream position.Put in place when cylinder presses down, after promptly compound dials put in place, position switch triggered, and sends signal to control system, thereby starts testing process automatically.

As preferably, box of the described end is located on the base plate of frame, and support plate is located on the end box.Make one-piece construction compacter, but setting operation button on the end box, handled easily.

Pressure is excessive to damage test plate (panel) to be measured in order to avoid, and as preferably, described portable plate is provided with adapter sleeve, and adapter sleeve is provided with thread segment, and constitutes the adjustable plate with this thread segment and cylinder piston rod and press down being connected of extreme position.Between adapter sleeve and the cylinder piston rod, regulate the length of both screw thread sections of screwing, can suitably regulate the extreme position that presses down of heating plate; Apparently, for improving degree of regulation, this thread segment can adopt fine thread.

Therefore, the utlity model has rational in infrastructure, be easy to characteristics such as making, especially have beneficial effect simple in structure, that reliability is higher.
