Signal type patching device for probe type detection device

The present invention is a signal patch cord used in a probe type detecting device, and particularly a signal patch cord which is elastically stretchable and can be directly inserted and fixed to a detecting station.

After the products such as printed circuit boards, semiconductor package components, and wafers are manufactured, they are tested by a dedicated probe type detector to confirm the yield and impedance of the product and maintain product quality. The probe type detecting device mainly uses the closely arranged fine probes to respectively contact the conductive circuits on the circuit board of the product, and then measures the electrical characteristics transmitted by each probe through a computer machine, thereby interpreting the circuit on the circuit board. Whether the electrical characteristics are in compliance with the specifications.

Since today's portable electronic products, such as smart phones, emphasize the ease of carrying and their functions are becoming more and more powerful, the circuit boards of these portable electronic products are not only greatly reduced in area, but also the circuit layout is often finely required. The magnifying glass can be used to examine one by one; thus, it also causes difficulty in manufacturing the probe type detecting device.

As shown in the first figure, the conventional probe type detecting device includes a jig 102 having a fine detecting probe 101, a detecting station 104 having a detecting hole 103 disposed under the jig 102, and a plurality of detecting holes arranged in the detecting hole. In the 103, a telescopic terminal 105 for detecting connection of the detecting probe 101, a plurality of signal transponders 106 electrically connected to the telescopic terminal 105, and a signal to be connected to each of the signal transponders 106 and capable of transmitting signals to the computer are used. The adapter disk 107 for detection analysis.

In the above configuration, the position of the top detecting end of the fine detecting probe 101 on the jig 102 must be set according to the circuit layout on the circuit board 108 to be inspected, and the telescopic terminals 105 on the detecting table 104 must be embedded one by one in the detecting hole 103. In addition, it is necessary to connect the signal patch cords 106 one by one. In the case where the processing area is limited, assembly and construction are quite difficult. Therefore, the applicant of this case has A detecting fixture having a floating plate (No. TW M446334) is counted, and each detecting probe 101 is protruded downwardly to the lower side of the jig 102 so that the detecting station located below the jig 102 The area of the 104 is less likely to be limited by the size of the circuit board 108 to be inspected, and the test station 104 can be easily constructed when the telescopic terminal 105 and the signal patch cord 106 are arranged.

After the above-mentioned prior art is implemented by the applicant, it is found that there is still room for improvement in the installation of the telescopic terminal 105 and the signal patch cord 106; one of them is that the telescopic terminal 105 is embedded in the detecting hole 103 of the detecting station 104, Each of the detecting probes 101 is arranged at an oblique angle. When the bottom end of the detecting probe 101 is pressed against the top of the detecting hole 103 and pressed against the telescopic terminal 105, as shown in the second figure, the detecting probe 101 is tilted at the bottom. The position is easily restricted by the periphery of the aperture of the detecting hole 103. If the pressing stroke is slightly more, the bottom end of the detecting probe 101 is deflected as shown in the third figure, especially in the case of repeated test, there may be Disadvantages of contact.

Another structure that can be improved in the prior art is that the telescopic terminal 105 and the signal patch cord 106 are designed to be separated and assembled. As shown in the fourth figure, the signal patch cord 106 must be disposed at the end first. The positioning sleeve 109 fixed in the detecting hole 103 is inserted, and the telescopic terminal 105 must first be inserted into a hollow column 111 having an outer diameter slightly smaller than the positioning sleeve 109 and provided with the spring 110, and then the telescopic terminal 105 is provided with The hollow columns 111 of the springs 110 are inserted into the positioning sleeve 109 from top to bottom. Therefore, it is necessary to assemble the detection holes 103 twice before and after the assembly, that is, the positioning sleeve of the signal extension cable 106 first. After the cartridge 109 is inserted into the detecting hole 103, the hollow post 111 is then inserted into the positioning sleeve 109, which is time consuming and labor intensive, and the manufacturing cost is relatively expensive.

In view of this, the creator has accumulated many years of research and practical experience in related fields, and specially created a signal patch cord to solve the complicated assembly between the detection hole, the signal patch cord and the telescopic terminal of the conventional inspection station. The lack of time and labor.

The purpose of the present invention is to provide a signal patch cable for use in a probe type detecting device, one end of which is electrically connected to the adapter disk, and the other end is a telescopic probe that can be directly inserted into the detecting platform. And the telescopic probe can be used for detecting the probe to be electrically connected to transmit the signal. To overcome the conventional technology, the telescopic terminal and the signal extension cable must be installed on the detection platform one by one. The shortcomings.

With the above configuration, the telescopic probe of the signal patch cable is elastically stretched and can be directly inserted and fixed in the fixing hole of the detecting table, and the telescopic terminal and the signal patching cable must be installed one by one in the prior art. The disadvantage of fixing holes improves the assembly speed of the test bench.

Furthermore, when the pressure contact end of the telescopic probe protrudes from the top end surface of the inspection platform, when the detection probe is arranged at an oblique angle, the position at which the bottom of the probe is tilted is not restricted by the periphery of the aperture of the detection hole, and improvement is improved. It is known that the detection probe has a slight pressure contact stroke, which may cause the bottom end to be skewed and the contact to be poor.

Embodiments of the various elements are further described below: when implemented, the pressure-contact end of the telescoping probe is a slightly concave concave surface to provide a positioning effect when the probe is pressed.

In the implementation, the other end of the signal patch cord is provided with a pin through the wire to be inserted into the adapter disc; the adapter disc is provided with finely arranged positioning perforations, and each of the positioning perforations is respectively provided with a hollow shape and inner The diameter is slightly larger than the pin for inserting the pin into the positioning adapter terminal; the signal measured by the detecting probe of the detecting device is transmitted through the telescopic probe of the signal patch cable, the wire, the pin, and the adapter terminal on the adapter disk Transfer to the computer for the operator to interpret.

In practice, after the pin is bent and inserted into the adapter terminal, the pin is positioned by the elasticity generated by the bending, so that the pin is not easily loosened from the adapter terminal.

In implementation, the finely arranged positioning perforations on the adapter disc are arranged in a matrix, the adapter disc is about 100×100 mm, and the number of perforations is about 4000-4200.

1. This design is provided with a telescopic probe that can be directly fixed in the fixing hole of the detecting table at one end of the signal patching cable, which can overcome the conventional technique and must install the telescopic terminal and the signal patching wire in the fixing hole one by one. The shortcomings increase the assembly speed of the test bench.
