Abstract

The invention discloses an FCT multifunctional matrix test board card, which comprises a circuit board, a matrix structure I is integrated on the circuit board, the matrix structure I is composed of a plurality of groups of signal relays, each relay is provided with an independent control bit, and the upper half part and the lower half part of the matrix structure I are short-circuited through a 0 omega jumper wire to form a matrix structure II; a function test part circuit is integrated on the circuit board, a communication interface circuit is arranged on the circuit board, the communication interface circuit comprises an RS485 communication interface and a USB communication interface, and the RS485 communication interface and the USB communication interface are respectively composed of a communication interface chip U29 and a communication interface chip U30; a core signal driving circuit is integrated on the circuit board, and the core signal driving circuit is composed of a decoder CD74H C4514M and 12 UCN5800L driving chips. According to the invention, in a smaller board card size, an exquisite circuit and a detachable matrix structure are adopted, and multiple function tests are realized. And meanwhile, the requirements of infinitely extensible test channel number and high-precision test equipment system integration can be met.

Description

technical field [0001] The invention relates to the technical field of test boards, in particular to an FCT multifunctional matrix test board. Background technique [0002] FCT testing can be said to be a non-standard industry. At present, there is no test board covering all the tests in the market. Some develop special boards according to customer needs, and some use boards from big brand companies. Most of them are boards with specific functions, and there is no integrated FCT multi-function test. [0003] At present, in the FCT industry, it is difficult to find a general-purpose FCT test board, which can not only meet the common test requirements of FCT, but also support the flexible expansion of the number of channels, and also support the system integration of standard instrumentation testing. To this end, we introduce a FCT multifunctional matrix test board. Contents of the invention [0004] The purpose of the present invention is to provide a FCT multifunctional ...
