The present invention relates to an interface FPCB used for FPCB inspection, and more particularly, to a test jig for inspecting an FPCB assay, comprising: an interface FPCB body in the form of a panel; A pad formed on a surface of the interface FPCB body to which the probe pin contacts; The interface FPCB is formed on one end of the body, relates to an interface FPCB, characterized in that consisting of a plurality of pads for connecting with the test PCB.

FPCB is a device used in the form of a cable for circuit connection of an electronic component unit. FPCB is also used as a main board of mobile communication terminal due to the development of technology, and it is also used by directly embedding a chip in the FPCB itself. Especially, FPBC is used as a circuit of a bent part in a folder type mobile communication terminal.

In order to check whether the FPC is functioning, conventionally, the method of directly contacting the FPCB with the PCB pattern connected to the inspection equipment by hand was used. This method has a very slow inspection speed and is not easy to contact with dust or foreign matter. There is no problem

Another test method was to use a clamp type jig, in which a probe was soldered to a pattern of a connected PCB connected to an inspection apparatus to contact the FPCB with the probe. Is worn out or damaged, and there is a problem in that replacement is impossible and thus the inspection jig itself cannot be reused.

Another inspection method is a method of electrically connecting the probe pin to the pattern of the connection PCB after fixing by the coupling means when electrically connecting the probe and the connection PCB. This method has the advantage of easy replacement when the probe is worn or damaged, but there was a problem that the assay of one FPC can not be examined at the same time.

In addition, the interface FPCB used up to now was used by making a via hole in the interface FPCB and directly soldering a connector to the central processing unit in the via hole. As a result, a new FPCB was produced every time a new product was developed, and since it was directly connected to the central processing unit, it was impossible to develop into an automated and universal type using an index table.

In order to solve the above problems, the present invention uses a single interface FPCB without changing or newly fabricating a hardware measuring device that is constructed in performing various electromagnetic circuit components, that is, various electronic component characteristics inspection. It is possible to measure and analyze the FPCB ASS'Y by software, change the via hole of the interface FPCB to the contact pad, and install the probing block at the end of the cable connected one-to-one to separate the system and interface FPCB. It aims to provide an interface FPCB inspection jig that can improve work efficiency, save labor costs, and maximize corporate profit by reducing development time and reducing investment costs by enabling automation.

In order to achieve the above object, the present invention provides a test jig for inspecting the PCB assay, the interface of the thin panel form FPCB body; A pad formed on a surface of the interface FPCB body to which the probe pin of the probe device contacts; Formed on one end of the interface FPCB body, characterized in that consisting of a connection pad connecting to the test FPCB to be examined.

In addition, the pad of the present invention, the probing block is in contact, the end of the probing block is provided with a connector for coupling with the data line of the computer, characterized in that the inspection is performed by software.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the accompanying drawings. 1 is a perspective view of one embodiment of the present invention, Figure 2 is a plan view of one embodiment of the present invention, Figure 3 is a perspective view of the alignment knob according to an embodiment of the present invention, Figure 4 is a side view of another embodiment of the present invention, 5 is a side view of another embodiment of the present invention.

First, the interface FPCB body 200 used in the practice of the present invention has a thin panel form as shown in FIG. The interface FPCB 200 is a kind of a printed circuit board, and a circuit corresponding to a circuit of the test FPCB 150 to be tested is printed.

In addition, the present invention interface FPCB 100 has a functional feature in that it serves as an interface for measuring the electrical flow of the test FPCB 150.

A plurality of circular contact pads 300 formed on the interface FPCB 100 have a test FPCB 150 to be examined as the probing block 500 of the inspection apparatus of the test FPCB 150 to be inspected is in contact. Test the electrical flow.

In this case, the inspection apparatus used is a device consisting of a probing block 500 having a probing block pin 520 corresponding to the number of pads formed in the interface FPCB as shown in FIG. 3. The control program of the inspection device is mounted on the computer main board that constitutes the central processing unit and the data passage.

The central processing unit receives and decodes the operation status command code, which is the schedule of the target of operation to be measured according to the type of measurement object, to make the switch operation schedule, and the processed data is stored in the memory of the switch configuration controller through the PCI bus. The switch configuration controller automatically controls the switch drive according to the work order command stored in the memory.

In order to measure the signal value by selectively connecting the number of the probe pin device desired by the user with various electrical component characteristic values and various analog signal values of the measurement target connected to the connection terminal of the probe pin device,

It was configured to measure connected to the multimeter measuring device.

1, at one end of the interface FPCB body 200, a connection pad 400 electrically connected to the test FPCB 150 to be inspected is formed.

More specifically, one side of the alignment adjuster 600 is provided with an alignment adjusting knob 620 for adjusting the alignment of the test pad 400 and the connection pad 400 of the interface FPCB 200. In addition, by arranging the alignment adjusting camera 640 at the lower portion of the alignment adjuster 600 at the position where the connection pad 400 is located, it is easier to align between the test FPCB 150 and the interface FPCB 200. It was configured to be.
