Description of the new type: [Technical field to which the new type belongs] This creation is a composite printed circuit board test fixture, especially a dedicated fixture and a conductive tape-type fixture (hereinafter referred to as a pcr-type fixture) ), And use a dedicated tester to perform the test, and use conductive tape and bumps on the fixture to replace the probe used by the conventional dedicated tester to prevent the probe from being damaged, and Leaving pin points on the printed circuit board to be tested can break through the test area and the number of test points, and the relative cost of the fixture is also greatly reduced. φ [Previous technology] According to the conventional printed circuit board (PCB, printed circuit board) is manufactured, it still needs to go through inspection procedures to test whether the printed circuit board is a good product; and the general printed circuit board manufacturers use Test fixtures can be roughly divided into De (iicate) testers, Universal testers, PCR testers, etc. Among them, for special-purpose testers, please refer to Figure j, which Mainly, there are opposite sockets on the testing machine. These sockets are equipped with jigs and probes respectively. These testing machines are cheap and fast in testing, but the jigs are expensive, especially Cooperating with printed circuit board _ The elastic probes like precision circuits on the circuit board are quite precise and expensive, and they are easily damaged and replaced, which increases the testing cost. Conversely, the universal testing machine is expensive, but the probes used are comparable. Generally, long needle fixtures are cheap; therefore, the generally beneficial use case is to use a universal testing machine when testing printed circuit board samples. When the printed circuit board is verified and mass production is to be started, change it. The special-purpose test machine meets the needs of mass production, but the special-purpose test machine still has the shortcomings of high unit price of the fixture and turning probe, and often needs to be eliminated and updated. Based on the above, it can be known that the traditional Dedicate fixture, The pcR type fixture performs the printed circuit board test M275412 test, but its disadvantages are as follows: 1. The cost of the special fixture crane is high, and it depends on the ability to test the circuit board with high difficulty, but the amount of needles and the cost do make this fixture The cost is much higher. 2. PCR type jig type has no needle marks for testing, which is impossible for all needle jigs. Its testability is far better than the above, but its test area and test points There are many restrictions that cannot be used in large quantities, and the price of its test machine is expensive. In response to the modification and supplementary work of the 6-point supplier, New Zealand has made a report on the "PCB special test machine and universal test machine" The new patent for the “converter board” and the new patent of Taiwan Patent Announcement No. 56 for “composite fixture probe structure improvement” have the following disadvantages. The above-mentioned combination of a dedicated test machine and a universal test machine Gu Zhifu Although the cost of the type fixture is much lower than that of the special type fixture, the test pin marks cannot be solved, and the troubleshooting and production are relatively complicated. [New content] B Creation purpose: " The creator of this creation has the shortcomings of the above-mentioned installations, so it is aimed at the crux of it, and began to seek improvement and make up for its shortcomings, in order to find a reasonable solution, after numerous studies and analysis. 'Finally, it is a cost to create a composite printed circuit board test fixture. The purpose of this creation is to provide a composite printed circuit board test fixture, which is provided with a relative base.' These bases are provided with a dedicated test Machine-connected probes, and there are corresponding conversion boards between these bases' These conversion boards are provided with test bumps corresponding to the printed circuit board to be tested, and pin tests corresponding to the probes Point 'and the surface of these conversion boards is completely clothed. When testing, M275412 can replace the probes used by the conventional special-purpose tester to test the fixture with conductive tape and bumps, which can be avoided. Damage to the probe and leaving pin points on the printed circuit board to be tested can break through the limitations of the test area and the number of test points, and the relative fixture cost is also greatly reduced. [Embodiment] First, as shown in Figs. 2 and 3, this creation is a composite printed circuit board riding jig, which is a fixture for testing the open / short circuit of printed circuit boards (OPEN / SH0RT). , The fixture is placed on the-test machine (not t), the test machine is a special type, and the reward is provided-the table top (not shown in Figure _4) 'The table top 10 is equipped with a In contrast to the base 20, only the lower base ⑼ is exposed in FIG. 2 except that the upper base 20 has exactly the same structure as the lower base 20. In addition, the lower base 20 is provided with a plurality of jacks. The 21 'turn jack 21 is changed according to the design of the printed circuit board to be tested, and probes 22 are respectively inserted in the jacks 21, and the-ends of the probes 22 are respectively exposed on the jack 21, and— The ends are respectively inserted into the jack 21 and pressed against a spring | 23, the other ends of the springs ㈤ are pressed against a conductive rod%, and the other ends of the conductive rods 24 respectively extend out of the jack 21 and the electrical signal. The circuit is connected, and through this circuit, it can be connected to a dedicated test machine. _ $ 'The base 20 is provided with a conversion board 30, and the conversion board 30 is provided with a bump 3 opposite to the test point of the printed circuit board 50. The copper pillar in this embodiment is familiar with this. Technicians can still be made of other conductive materials, and the other side is provided with a probe 32 that is opposite to the base and the probe, and the ten points 32 are connected to the bumps 31 by electrical communication lines. The connection, in this embodiment, the electrical connection line is steel. The manufacturing method is the same as that of a general printed circuit board, and the conversion board has bumps on one side and is covered with conductive tape 40. The conductive tape has conductivity in the up and down direction. However, the characteristic of being unable to conduct electricity in the left and right directions' and a printed circuit board 50 to be tested can be placed on the conductive tape 40. Bei Congshi 'Qing refers to FIG. 4, first fix the upper and lower base 20 to the upper and lower M275412 ends of the countertop 10 respectively, and keep the upper and lower base 20 at a certain distance, then change the conversion board 3 〇 After being placed on the upper and lower bases 20, respectively, a conductive adhesive tape 40 is covered on the surfaces of the conversion boards 30, and then the printed circuit board 50 to be tested is placed on two conductive adhesive tapes 40 Fa1. When the upper and lower bases 20 are pressed toward the middle, the points to be measured that are raised on the surface of the printed circuit board 50 to be tested will be pressed against the conductive tape 4 and contact the bumps 31 opposite to the conversion board 30. Where the printed circuit board 50 to be tested is not raised, it will not be in contact with the conversion board 30. In this way, the point to be tested that is in contact with the bump 31 can be contacted with the probe 22 through the probe test point 32 and through the probe. 22 The signal is transmitted to the test machine for testing. φ As mentioned above, this creation has the following advantages: 1. Using a dedicated test machine for testing work is not only cheap and fast. 2 · Press-as for the printed circuit board used in mobile phones. @ 其 _ The board area is small and the density of the probe points is high. For relative testing, the conventional device must use a probe that conforms to a very fine, in order to perform the test. There will be a short circuit situation. On the other hand, through the conversion of the conversion board 30, the probe 22 does not need to directly contact the printed circuit board 50 to be tested, so the probe 22 does not need to use a special specification probe, which can save a lot of time. Big cost. • & Because the bumps 31 on the conversion board can be made very small as needed, the test area and the number of points in a unit area can be increased. 4. As the conversion board 30 is covered with a conductive adhesive tape 40, the printed circuit board 50 to be tested does not need to be in direct contact with the bumps 31 on the conversion board 30, thereby avoiding pin points or embossing, thereby avoiding The printed circuit board 50 was damaged. In summary, the composite printed circuit board test fixture created by this creation is simple and practical, and can be applied to four-wire micro-ohmic (Ω) testing, which can save costs and increase effectiveness, fully complying with new patent requirements, and special features. File a patent application according to law. M275412 [Schematic description] Figure 1 is a schematic diagram of a conventional device.
