Abstract

PURPOSE:To enable a multiplicity of probes to be arranged easily without causing positional deviation of the tip ends of the probes, by providing a plurality of transparent plates of a non-conductive material between the probes so that probes are allowed thereby to slide a little in the axial direction while they are inhibited from moving in the transverse direction and pinned down at the position of the holes provided in the transparent plates and that the non-conductive transparent plates serve as separators. CONSTITUTION:Probes 4 are set by means of a plurality of transparent plates 6 which are formed of a non-conductive material and provided in apertures 2 of a base 1. The transparent plates 6 are thin plates of quartz or epoxy material for example and are provided with as many holes 7 as the probes to be mounted there. The holes 7 of each transparent plate are aligned with the holes of the other plates so that the probe is passed through the holes of the other plates so that the probe is passed through the holes 7 thus aligned. The hole 7 has a diameter slightly larger than that of the probe 4 so that each probe 4 is mounted slidably in the holes 7. The proves 4 are connected to a contact terminal with an external unit, namely to a lead-out section 12 by a wire 8 of copper or the like to which the probes 4 are welded.

(Prior Art) This type of test probe assembly consists of a base with an opening, and an appropriate number (usually about 20 to 400) of probes (usually about 20 to 400) provided in the opening of the base so that their tips are on the same plane. The tip of each probe can be brought into contact with the electrode lead-out portion of the semiconductor chip, that is, the bonding pad. However, as shown in FIGS. 6 and 7, the conventional test probe assembly has a base (

(Problems to be Solved by the Invention) As mentioned above, in the conventional configuration, the base side of each glove was simply embedded and fixed with resin, so the bending of the probe during use could cause the surface of the resin to A gap is created between the resin and the probe in the probe-resin contact area (5'). If such a gap occurs, the tip of the probe will become misaligned. Normally, the bonding pad is 60 to 150μ square, and the tip of the glove is approximately 50μ square or 50μ diameter, so if the probe tip shifts slightly, the tip of the probe (4) will move as shown in Figure 8. had the disadvantage that it could come off the pad (■) and interfere with the inspection. Furthermore, the number of globes provided in the opening 12) can reach 500-400, in which case it becomes difficult to connect the probes to the circuit or drawer of the base (1), and therefore a large number of probes is required. There is a problem in that an assembly including this is difficult to manufacture.

Furthermore, an elastic transparent nonconductor is filled between the transparent plates, so that each probe can be moved slightly in the axial direction.

(Function) Therefore, in the test probe assembly of the present invention, when each probe comes into contact with the bonding pad of the semiconductor chip to be checked, it retreats slightly in the axial direction, so that no unreasonable force is applied, and the movement of the probe is only 2. Since the probe is guided and restrained by holes in more than one transparent plate, the direction of the probe is always constant, and the tip of the probe properly contacts the pad. In addition, if five or more transparent plates are provided, the intermediate plate will serve as an insulating separator, which will prevent the wires from coming into contact with each other between the glove and the drawer. Since wiring is possible, it becomes easy to install a large number of probes.

In the illustrated embodiment, the number of transparent plates (6) is six and four, but it goes without saying that the number of transparent plates (6) may be greater than that, and the intermediate transparent plates other than those on both sides are used as separators. As the number of transparent plates (6) increases, it becomes easier to attach a larger number of probes. However, since using too many sheets increases the thickness, it goes without saying that there is a limit to how many sheets can be used. Therefore, when the number of probes is small, two transparent plates may be used.
