Definitions
- an electrical connection between the inspection target and a signal processing device that outputs an inspection signal is used.
- a probe unit that accommodates a plurality of contact probes is used.
- the probe unit can be applied to highly integrated and miniaturized inspection objects by narrowing the pitch between contact probes with the progress of high integration and miniaturization of semiconductor integrated circuits and liquid crystal panels in recent years. Possible technologies are progressing.
- packages in which electrodes are disposed on both sides have been used.
- Patent Document 1 when the technique of Patent Document 1 is applied to PoP and a conduction state inspection between two stacked semiconductor packages is performed, a suction block is provided between the two semiconductor packages, and a suction hole of the suction block is secured. Therefore, the inspection cannot be performed with two semiconductor packages arranged in the stacking direction. For this reason, the inspection must be performed in a state where the two semiconductor packages are shifted from the stacking direction, the signal conduction path between the electrodes becomes longer, the inspection tact time becomes longer, and the signal path length There is a problem that the inspection accuracy is lowered due to variations.
- an inspection unit includes two substantially plate-like contact objects, at least one of which has electrodes on both sides, arranged in the stacking direction.
- An inspection unit for inspecting one contact object which is in contact with an electrode provided on the surface of one contact object on one end side in the longitudinal direction and the other contact on the other end side.
- the first contact probe that contacts the electrode of the object and the electrode provided on the back surface of the one contact object on one end side in the longitudinal direction and for inspection on the other end side A second contact probe that comes into contact with the electrode of the substrate that outputs the signal, and a suction holding portion that sucks and holds the one contact object, and a plurality of the first contact probes in a predetermined pattern did A first probe holder for receiving and holding the plurality of second contact probes, a second probe holder for receiving and holding the plurality of second contact probes according to a predetermined pattern, and the first probe holder. And a base portion that holds the other contact object
- FIG. 2 is a partial cross-sectional view showing the configuration of the main part of the inspection unit 1 according to the present embodiment, and is a diagram showing the detailed configuration of the probe 2 accommodated in the probe holder 4.
- the probe 2 (first contact probe) shown in FIG. 2 is for connecting the semiconductor package 100 with the first plunger 21 that contacts the connection electrode 201 of the semiconductor package 200 when the semiconductor packages 100 and 200 are inspected.
- a second plunger 22 that comes into contact with the electrode 101 and a coil spring 23 that is provided between the first plunger 21 and the second plunger 22 and that connects the two first plungers 21 and the second plunger 22 in a telescopic manner. .
- the first plunger 21 and the second plunger 22 and the coil spring 23 constituting the probe 2 have the same axis.
- the coil spring 23 expands and contracts in the axial direction, so that the impact on the connection electrodes of the semiconductor packages 100 and 200 is reduced and the load on the semiconductor packages 100 and 200 is reduced.
- the probe 3 reaches the connection electrode 102 of the semiconductor package 100 via the second plunger 32, the tightly wound portion 33 a, and the first plunger 31.
- the first plunger 31 and the second plunger 32 are conducted through the tightly wound portion of the coil spring 33, so that the electrical signal conduction path can be minimized. Therefore, it is possible to prevent a signal from flowing through the coarsely wound portion of the coil spring 33 during inspection, and to reduce and stabilize the inductance.
- the probe 2 has a similar conduction path.
- the second member 6b is provided on the main surface on the side different from the lamination side of the first member 6a and the hole portion 66, which is a substantially cylindrical hole penetrating in the plate thickness direction, and 2nd groove part 67 which is an annular
- the second groove 67 is provided with an O-ring 400 that ensures hermeticity when connected to an intake pump (not shown).
- the holder hole 46 includes a small diameter portion 46a having an opening at the lower end surface of the probe holder 4 and a large diameter portion 46b having a diameter larger than the small diameter portion 46a.
- the small diameter portion 46a has a slightly larger diameter than the diameter of the outer periphery of the holding portion 71 excluding the protruding portion 711.
- the large diameter portion 46 b is slightly larger than the diameter of the outer periphery of the coil spring 72 or the diameter formed by the edge of the protruding portion 711.
- each flange portion on the tip end side and the boundary wall surface between the large diameter portion and the small diameter portion of the holder hole may be tapered. Thereby, positioning in the direction perpendicular to the axial direction of the probe when the probe is attached to the holder can be performed more reliably.
- the probes 2 and 3 are not limited to those composed of plungers and coil springs, but may be pogo pins or wire probes that obtain a load by bending a wire into a bow shape. Further, the tightly wound portion and the coarsely wound portion of the coil spring may be reversed. In this case, the lengths of the base end portions of the first and second plungers are preferably opposite. Further, the probe holder can be appropriately changed in accordance with the above-described probe.
