Embodiment 1

[0027] The invention provides a cold plate inspection method, which is suitable for the cold plate with the counterbore distributed at the edge of the cold plate, such as figure 1 As shown, including checking the appearance of the counterbore on the cold plate, checking the size of the bottom hole of the counterbore on the cold plate, and checking the number of counterbore holes on the cold plate, please refer to the structural diagram of the cold plate figure 2 .

[0028] Specifically, please continue to refer to figure 1 , when checking the appearance of the counterbore on the cold plate, first, observe with the naked eye whether the counterbore on each cold plate is a regular counterbore, that is, whether the size of the counterbore is consistent, and take out the cold plate with the counterbore of inconsistent size; secondly, use The transparent diaphragm is covered on the surface of the cold plate, and the position and size of the counterbore on the cold plate are inspe...

Abstract

The invention discloses a cold plate inspection method, and belongs to the technical field of cold plate inspection. The cold plate inspection method comprises the steps that the appearances of counter bores in cold plates are fully inspected, the bottom hole sizes of the counter bores in the cold plates are casually inspected and the number of the counter bores in the cold plates is fully inspected, when the appearances of the counter bores in the cold plate are fully inspected, whether the sizes of the counter bores in each cold plate are regular counter bores or not is observed with naked eyes, and the cold plates with obviously inconsistent sizes are taken out; and the surface of each cold plate is covered with a membrane with a transparent legend ratio of 1: 1, and the positions and sizes of the counter bores in the cold plates are inspected. According to the invention, the inspection items of the cold plates are split and sorted and inspected according to the difficulty degree ofthe inspection items, so that the inspection efficiency is improved; and during full-leakage-detection punching, the cold plates are grouped and stacked in a staggered mode, so the number of counterbores in the cold plates is convenient to observe, it is avoided that each cold plate is taken out to be inspected again, the inspection efficiency is improved, and the omission ratio is reduced.

Description

technical field [0001] The invention relates to the technical field of cold plate inspection, in particular to a cold plate inspection method. Background technique [0002] With the rapid development of electronic technology, electronic components on printed circuit boards in electronic products continue to develop in the direction of miniaturization and high integration, which brings a series of heat dissipation problems. High-power printed circuit boards are due to It has excellent heat dissipation performance and dimensional stability, and is used on a large scale. [0003] As a kind of printed board, the cold plate does not produce iron oxide scale because it is rolled at room temperature. Therefore, the cold plate has good surface quality and high dimensional accuracy. Coupled with annealing treatment, its mechanical properties and process performance are better than those of hot rolling. Sheet steel has gradually replaced hot-rolled sheet steel in many fields, especia...
