Abstract

PURPOSE:To allow an inspecting device to diagnose optionally its functions by itself by interposing a solid pattern substrate, and short-circuiting when an optional couple of probe pins of the inspecting device are brought into contact with each other. CONSTITUTION:Tips of probe pins of the inspecting device A contact the solid pattern substrate 8 which has a conductive surface 10 as its top surface, and a previously specified couple of pins which do not short-circuit also short-circuit by contacting the conductive surface in addition to couples of pins, e.g. B1 and B2, and C1 and C2 which conduct to each other, so short-circuit display is obtained for all. Thus, when the inspecting device A makes a self-diagnosis, the solid pattern is interposed to short-circuit each couple of pins, so data on that is stored in an IC memory then the inspection of the pattern of the printed wiring board and the self-diagnosis of the inspecting device are executed optionally and simultaneously.

In general, pattern inspection of printed wiring boards involves placing a probe bin in contact with lands that are part of the pattern of the printed wiring board to be inspected, and inspecting the presence or absence of continuity between each land. By comparing the standard data of patterns of good printed wiring boards stored in the device (IC memory) with the data of each test object, printed wiring boards with defective circuit parts such as disconnections or short circuits in the patterns can be detected. This is a way to discover.

However, with the above inspection method, if there is a defective part in the probe bin of the inspection equipment used for this, or if there is a disconnection in the relay cable connecting the probe bin and the inspection machine main body, the printed wiring board may be damaged. It is not possible to perform a regular cone inspection of the pattern.

First, a method for inspecting the pattern of the printed wiring board shown in FIG. 1 will be explained. The printed wiring board that is the object to be inspected (
1) is usually a substrate made of glass/epoxy material or paper/phenol or epoxy material, and a pattern (2) which is a conductive circuit is formed on this substrate, and a part of this pattern has through holes. (2), and a land (3) as a conductive portion is formed around this pole. Therefore, the probe bin (4) in the inspection device (5) is lifted up by the holder (5) via a Tsubaki Genretsu Yubo Yubogo 1 Nof descending machine, etc., and the tip of the probe bin is lifted. By making contact with the lands (3) of the object to be inspected, it is possible to inspect the conduction state between the lands in the pattern of the printed wiring board. At this time, it is important to specify in advance each pair of pins that are not obviously short-circuited so that an indication that the printed wiring board is being inspected can be obtained.

Next, a self-diagnosis method of the inspection apparatus using the solid pattern board shown in FIG. 2 will be explained. The solid pattern board (9) having a conductive surface on its surface is usually a glass/epoxy material board, or a paper/phenol or epoxy material board, which is the base material of a printed wiring board, and at least one surface is coated with copper foil or the like. The conductive surface (10) is adhesively formed. Preferably, a conductive surface is adhered to the entire surface, which is advantageous for contacting each pair of probe bottles and short-circuiting them. However, portions that do not come into contact with the probe bin, such as the peripheral portion of the substrate, may be bonded nonconductive surfaces.

The probe pin (4) in the inspection device (2) is attached to its holder (5).
The tip of the probe bottle that has been moved by the press while being supported by contacts the solid pattern substrate (9) having a conductive surface (10) on the surface, and connects each pair of pins, for example, Bl and B2. Or, in addition to each pair of conductive pins such as C1 and C2, each pair of pins specified in advance that are not clearly shorted are also brought into contact with the conductive surface and shorted, so all short circuits are displayed. is done. Therefore, it is possible to distinguish between a printed wiring board inspection and a self-diagnosis of the inspection device by displaying short or open pins specified in advance.

In this way, self-diagnosis on the inspection device surface shorts each pair of pins by interposing a solid pattern, so if this data is stored in the IC memory, even if the standard data of the printed wiring board is stored separately. However, during -g, the inspection of the pattern of the printed wiring board and the self-diagnosis of the inspection device can be carried out at any time. At this time, by specifying in advance a pair of pins in a non-conducting part of the printed wiring board pattern that will not obviously be shorted, it is possible to
When this specified pin comes into contact with the solid pattern board placed at a predetermined position on the tangible device to be tested, a short circuit will be displayed, while the printed wiring board, which is the object to be tested, is placed in a predetermined position. In this case, when the pin comes into contact with a non-conducting part that is clearly not short-circuited, the pair of pins designated in advance will be displayed as open. In this way, the short-circuit display and the open display distinguish the inspection of the printed wiring board from the self-diagnosis of the inspection apparatus.
