Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a board fixing structure for a function tester.

[Prior Art] The function tester has been described in detail in the specification of Japanese Patent Application No. 60-82237 previously filed by the applicant of the present application. To summarize, this is a printed wiring board on which electric parts are mounted. Is fixed to the XY table, the measuring pin of the XY table is moved to an arbitrary position on the XY plane, and the measuring pin is moved in the Z direction perpendicular to the XY plane at the moved position to a position corresponding to the position. Is a device for contacting a point on the substrate with a signal at the contact point, the movement of the measuring pin is executed by program control by a computer, and the position information in the XY plane to move the measuring pin is, for example, It is input to the computer using a digitizer or the like.

A conventional structure for fixing a substrate to be inspected to the XY table of such a function tester is shown in FIG. In the figure, reference numeral 1 is a board (side surface is shown; attached electric parts are omitted), and 30 is a slidable board fixing frame. The board fixing frame 30 has a groove having the thickness of the board, and holds the board by sandwiching both edges of the board by the grooves of the two frames. The board fixing frame 30 is mounted so as to be slidable on the outer frame of the XY table.

[Problems to be Solved by the Invention] In the conventional structure as described above, when the substrate to be inspected is replaced, one of the substrate fixing frames 30 must be slid to pull out the substrate 1, and the thickness of the substrate 1 However, there is a problem in that the board fixing frame 30 must be recreated and the fixing method is sandwiching, so that there is a risk of bending the board.

This invention has been made to solve the above-mentioned problems in the conventional one, and a board fixing structure that can securely fix the board regardless of the size of the board to be inspected and that allows easy replacement of the board. The purpose is to get.

[Means for Solving the Problem] In this invention, a slide frame for holding the substrate fixing frame in a state of being slidable in the Y direction, a slide member capable of sliding in the X direction on the substrate fixing frame, and a substrate provided on the slide member. And a fixing pin for fixing the position of.

[Operation] By moving the board fixing frame in the Y direction and moving the slide member in the X direction, it becomes easy to fix the board regardless of the size of the board, and the Z direction can be suppressed only by the XY table top cover. It is possible to easily cope with dimensional changes in the direction.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. First
The figure is a perspective view showing an embodiment of the present invention. In the figure,
The same reference numerals as those in FIG. 3 indicate the same or corresponding portions, and 11 indicates XY.
Outer frame of table, 12 top cover of XY table, 13 signal input pin, 14 pin holding member, 2 slide frame, 3a and 3b board fixing frame, 4 slide member, 5 carriage,
51 is a spindle and 6 is a measuring pin.

An X driving device (not shown) drives the spindle 51 in the X direction while mounting the carriage 5 and keeping the carriage 5 parallel to the Y axis. The carriage 5 carries a measuring pin 6 and a Y driving device (not shown). ) On the spindle 51
Driven in the direction. Therefore, the measuring pin 6 moves to the designated position on the XY coordinates. At this moved position, the measurement pin 6 is moved in the Z direction perpendicular to the XY plane by a signal from a computer (not shown), and is moved to a corresponding point on the substrate 1 (not shown in FIG. 1). , And the signal at the contact point is input to the computer and processed.

The power supply and input / output signals of the electric circuit of the substrate 1 (the output signal is omitted if it is unnecessary to derive the output signal for the purpose of inspection) are input to the substrate 1 via the signal input pins 13. With the XY table top lid 12 closed, the signal input pin 13 comes into contact with the corresponding position on the substrate 1.

FIG. 2 is a side view showing the board fixing frames (3a) and (3b) of FIG. 1, and the same reference numerals as those in FIG. 1 denote the same parts, 41 is a fixing pin, and 42 is a fixing screw.

The two slide frames 2 are fixed to the XY table outer frame 11 parallel to the Y axis at a predetermined distance in the X direction. A pair of substrate fixing frames (3a) and (3b) are bridged over the two slide frames 2.
Both ends of each substrate fixing frame are engaged with the sliding structure of the two slide frames 2 so that each substrate fixing frame can be slid in the Y direction while keeping the posture parallel to the X axis. When the slide finishes the positioning in the Y direction, each substrate fixing frame is fixed to the slide frame 2 at that position (fixing means is not shown).

At least two slide members 4 are provided, and slide on the substrate fixing frame 3b in the X direction to move. When the positioning is completed by this movement, the board fixing frame 3b is fixed by the fixing screw 42.
Fixed on top. A plurality of holes are formed at the end positions of the substrate 1, and the fixing pin 41 provided on each slide member 4 is provided.
Engage the corresponding holes in the substrate 1 to fix the position of the substrate 1 in the XY plane. If the XY table top cover 12 is closed in this state, the position of the board 1 in the Z direction is fixed, and the signal input pin
Power and signals from 13 are connected to the board 1.

The mounting surface on which the fixing pin 41 of the slide member 4 is provided and on which the substrate 1 is mounted, and the surface of the stepped portion of the substrate fixing frame (3a) on which the substrate 1 is mounted are located in the same Z direction. To configure.

With such a structure, the substrate 1 can be easily replaced, and the substrate fixing frame on the slide frame 2 can be adjusted according to the size of the substrate 1.
By moving the positions of 3a and 3b and the position of the slide member 4 on the substrate fixing frame 3b, the substrate 1 having any size can be obtained.
Can also be easily fixed.

[Advantage of the Invention] As described above, according to the present invention, a substrate having any size can be easily and surely fixed with a simple structure.
