Abstract

The invention discloses a universal COB module testing mode and belongs to the field of manufacturing of touch panels. The universal COB module testing mode comprises the following processes that a COB module to be tested is connected to an adapter board; one end of the adapter board is led to a function board with an integrated circuit (IC) through a wire jumper according to a channel sequence; at the other end of the function board and a data communication end are sequentially connected to a testing board; the testing board is connected to a computer; and the test is performed by utilizing testing software. According to the testing method, even if the terminal mainboard adopts different ICs, the testing method and the testing software are different, the method can integrate different types of COB module tests, a testing tool is not required to be modified, only the wire jumper sequence is required to be changed, and the method is high in testing accuracy, high in timeliness and high in universality.

Description

COB module universal testing mode

Technical field

The present invention relates to COB module universal testing mode, COB module (chip On board) is the module that chip is positioned at mainboard, belongs to contact panel and makes the field.

Background technology

At present the test of COB module mostly is that the IC in the buying special project is processed into PCB(Printed Circuit Board printed circuit board in the industry) carry out vacation and tie up rear test, perhaps line is tested after the installation.

False binding mode need to be according to product I C requirement, and first design concept figure, wiring drawing are purchased corresponding IC again and processed pcb board, card extender, if without IC agency's support, layout design, drawing evaluation, a minute position program, method of testing all are difficult to solve.Efficient is low can't to satisfy the shipment of COB sample.Secondly, the mode of line test after the installation, test seriously lags behind especially, character surveillance in the time of can't satisfying volume production; Even buying professional test equipment, the electric property of test contact panel, effect is not directly perceived yet.

Summary of the invention

The invention discloses COB module universal testing mode.Detailed process is: on COB module access card extender to be measured, the other end of card extender is introduced on the feature board with IC of designed, designed with wire jumper according to the passage order, and the I/O communication ends with this feature board accesses on the test board successively again.With data line test board is connected with computer, utilizes testing software to test.The advantage of this method of testing: feature board is compatible strong, even terminal mainboard uses different IC, and method of testing, testing software difference, the method also can be integrated, maximum 28+16 passage, the following COB module of 8 ＂ supported.The COB module test of different cultivars need not be changed testing tool, only needs the change of wire jumper order is got final product, and the card extender that need to use is also general with other testing apparatus, and test accuracy is high, and is ageing strong, has more universality.

The invention provides COB module universal testing mode, comprise the steps:

Step 1: on COB module access card extender to be measured;

Step 2: the other end of card extender is introduced on the feature board with IC with wire jumper according to the passage order;

Step 3: access successively an other end data communication ends of this feature board on the test board;

Step 4: with data line test board is connected with computer, after the configuration of use test software, tests;

By above step, just finish COB module universal testing mode.

Embodiment

The below further describes with implementation of the present invention:

Step 1: on COB module access card extender to be measured;

By above step, just finish COB module universal testing mode.

Embodiment:

Step 1: such as Fig. 1 with the Circuit of FPC(Flexible Printed shown in the A of COB module flexible printed circuit board) the corresponding connector in FPC golden finger place shown in the B among golden finger access Fig. 2;

Step 2: according to the design drawing requirement, according to sensor passage order with being connected with the use of the wire jumper interface on the feature board of IC wire jumper shown in the D among the card extender wire jumper interface shown in the C among Fig. 2 and Fig. 3;

Step 3: will be connected by communication interface on the supporting test board shown in the G among definition and Fig. 4 with communication interface on the feature board of IC shown in the F among Fig. 3;

Step 4: such as Fig. 5 usage data line supporting test board is connected with Test Host shown in the H, makes it to carry out proper communication.Thereby utilize testing software to import the function that corresponding test configurations realizes detecting COB module quality.

Though the present invention is described by above-mentioned example, but still can change its form and details, make without departing from the spirit of the present invention.Above-mentioned for the most rational using method of the present invention, only for the present invention can implementation one of mode, but not as limit.Those skilled in the art is understood, and can carry out many changes to it in the spirit and scope that claim of the present invention limits, revise, even equivalence, but all will fall within the scope of protection of the present invention.
