New energy automobile control circuit board performance test method

Abstract

The invention relates to a new energy automobile control circuit board performance test method. The method mainly comprises the following steps: plate clamping, height adjusting, dust raising, dust pile flattening, collecting and treating and other procedures are conducted; used performance detection equipment comprises a fixed base, a working frame, a dust raising machine, a clamping device and acollecting cabinet, the working frame is installed at the upper end of the fixed base, the dust raising machine is fixed to the upper end of the working frame, the clamping device is arranged in theworking frame, the collecting cabinet is arranged at the lower end of the working frame, and the collecting cabinet is arranged at the upper end of the fixed base in a sliding mode. According to the invention, the problems that the dust accumulation height on the surface of the circuit board cannot be controlled, the dust accumulation is uneven, the experimental test result is influenced, and onlythe circuit board with fixed length and width can be clamped when the circuit board is clamped in the traditional dust prevention performance test method for the new energy automobile control circuitboard can be solved.

Description

technical field [0001] The invention relates to the technical field of performance testing of an automobile control circuit board, in particular to a method for testing the performance of a new energy automobile control circuit board. Background technique [0002] With the development of China's industry, the new energy vehicle market will be the trend of future development. Among them, the controller of the new energy vehicle acts as the "central nerve" and plays an important command role. Its normal operation needs the support of various circuit boards, and the circuit boards are divided into: ceramic circuit boards, alumina ceramic circuit boards, Aluminum nitride ceramic circuit boards, circuit boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc., which are widely used in the field of new energy vehicles, and circuit boards Making the circuit miniatur...

Problems solved by technology

[0005] The present invention can solve the problem of the traditional new energy vehicle control circuit board anti-dust performance test method, usually unable to accurately control the dust accumulation height on the surface of the circuit board, resulting in poor test results for simulating dust accumulation conditions, and due to the accumulation of a large amount of dust in a short period of time Dust, resulting in uneven dust piles, unable to simulate the dust accumulation on the surface of the circuit board under natural conditions, affecting the experimental test results and when clamping the circuit board, often only the circuit board with a fixed length and width can be clamped For circuit boards of different lengths and widths, it is necessary to replace the clamping equipment, which wastes manpower and material resources.
