Embodiment 1

[0049] In this embodiment, the connector of the circuit board under test matches the connector of the test signal output unit of the circuit board under test and the output signal receiving unit of the circuit board under test.

[0050] like figure 1 As shown, the circuit board functional integrity testing platform of the present embodiment includes: a core processing board, a computer, an external power supply, a signal generator and an oscilloscope; wherein, the core processing board includes a central data processor, a communication unit, a circuit board to be tested The test signal output unit, the output signal receiving unit of the circuit board under test, the signal switching unit, the display unit, the jumper connection unit and the onboard power supply unit; the external power supply is connected to the onboard power supply unit of the core processing board through a power cable The central data processor, communication unit and display unit of the circuit board to b...

Embodiment 2

[0066] like image 3 As shown, the connector of the circuit board under test in this embodiment does not match the connector of the test signal output unit of the circuit board under test and the output signal receiving unit of the circuit board under test, and the circuit board under test is connected to the core processing unit through a jumper. on the jumper connection unit of the board; the central data processor sends a digital signal as a test signal, and the test signal is transmitted to the circuit board to be tested through the jumper connection unit. After the circuit board to be tested performs the test function, the output signal of the circuit board to be tested is transmitted to to the central data processor. Others are the same as embodiment one.

Abstract

The invention discloses a functional completeness testing platform and testing platform for circuit boards. The testing platform includes a core processing panel, a computer, an external power source, a signal generator and an oscilloscope. The testing platform has a feature of universality. The computer can set different testing schemes for the different to-be-tested circuit boards. According to the invention, expansion and transformation can be made on a physical interface of the testing platform directing at the to-be-tested circuit boards having different input and output interfaces; actual signals can be simulated and set digital signals can also be input for the to-be-tested circuit boards, so that response to the actual input signals of the to-be-tested circuit boards can be judged and response to digital signals with strict requirements of the to-be-tested circuit boards can also be judged. The computer program of the invention has interfaces for other programs and data statistics and subsequence treatment can be made according to testing results. Only one person is needed in the whole testing process from cable connection to electrification testing, so that the production efficiency is improved substantially.

Description

technical field [0001] The invention relates to an electronic product testing technology, in particular to a testing platform and a testing method for the functional integrity of a circuit board at the front end of a large-scale medical device PET / CT. Background technique [0002] The circuit board is one of the important components of electronic products, which undertakes the functions of data input, data processing and data output. Data input and data output are collectively referred to as data transfer. In order to accurately realize the functions of electronic products, it is necessary to ensure the correctness of data transmission and data processing of product circuit boards. [0003] Nowadays, most electronic products are operated on assembly lines. Before the electronic products are assembled, it is necessary to ensure the qualification of each product assembly component, including the qualification of the product circuit board, especially for large-scale medical eq...
