Detailed description of the invention
The physical connection schematic diagram of the position Fig. 1 interface board of the present invention.
Specific embodiment
A specific embodiment of the invention is described in detail with reference to the accompanying drawing.
Test environment.
Test natural environment requirement: should be under normal test atmosphere, i.e. temperature: -20 DEG C~+60 DEG C；It is relatively wet
Degree: within 65%；Air pressure: 86kPa~106kPa.
Test item and index.
Interface board requires to complete the connection of test environment as shown in Figure 1.
Computer techno-stress device power-up, for completing the test of interface board J2 and K2 network interface, J1 and K1 aviation
The connection of socket USB flash disk and reading and writing data performance test.
Testing procedure:
Before interface board is powered on power up test, observation inspection first is carried out to the appearance of interface board, mainly check for losing part, damage part,
The bad phenomenons such as scratch, more tin, few tin, failure welding, component skew, it is bad if any being then determined as, depot repair is carried out, it is no
Then enter detection line and is powered up detection.
Indicate lamp test: D.C. regulated power supply is set as 3.2V 1A, and multimeter is allocated to DC voltage shelves, and red test pencil connects
Power supply output cathode, black meter pen connect power supply output negative pole, and whether the output voltage for reading DC voltage shelves measurement power supply is 3.2V；Such as
Continue to test in next step for 3.2V, otherwise adjusts direct current power source voltage and export knob, confirmation voltage output is 3.2V.
D.C. regulated power supply is opened, powers to interface board J3 power supply power supply interface and observes three LED light on pinboard
Whether D1 D2 D3 all lights, and all lights up as normal condition, does not light normally all then as rejected product.
