Method and device for determining structural error

Abstract

The invention discloses a structural error determination method and device. The method includes the following steps that: the first physical parameters of each of a plurality of first devices are detected separately, wherein the first physical parameters are used for reflecting the influence of structural error on thermal conduction performance between first electronic components and first heat dissipation structures in the first devices; reference physical parameters are determined according to the plurality of first physical parameters respectively corresponding to the plurality of first devices; the second physical parameters of a second device is detected, and the second physical parameters are compared with the reference physical parameters; and whether structural error between the second electronic component of the second device and the second heat dissipation structure of the second device is within an allowable range is determined according to the comparison results of the second physical parameters and the reference physical parameters. With the method of the present invention adopted, the determination of the structural error of assembled equipment is more efficient and direct. The method can also be flexibly applied to a production line, thereby improving the efficiency and quality control of mass production.

Description

technical field [0001] The invention relates to the technical field of structural error determination, in particular to a structural error determination method and device. Background technique [0002] At present, the quality assurance of finished products is mainly to establish a certain tolerance range for each part according to the design requirements during design, to assemble the qualified parts according to the process regulations, and then assemble the qualified parts into the final equipment. However, for equipment that cannot be disassembled and inspected after mass production and assembly, it is difficult to have a method for judging whether the structural error inside the equipment is qualified after assembly. [0003] Especially for the equipment with heat dissipation elements in the sealed casing, due to the undetectability of the interior of the casing, it is difficult to detect the structural errors of the internal parts after assembly, and the structural erro...

However, for equipment that cannot be disassembled and inspected after mass production and assembly, it is difficult to have a method for judging whether the structural error inside the equipment is qualified after assembly

[0003] Especially for the equipment with heat dissipation elements in the sealed shell, due to the undetectability of the inside of the shell, it is difficult to detect the structural errors of the internal parts after assembly, and the structural errors will affect the heat dissipation performance and heat dissipation of the internal heat dissipation elements. The thermal conductivity of the structure further affects the heat dissipation performance of the entire device
