AI Technical Summary

Technical Problem

In existing technologies, circuit boards are not easy to fix during salt spray testing, resulting in poor back-side testing performance when laid flat, which affects the accuracy of the evaluation.

Method used

A circuit board testing device was designed, which uses a sealed cabinet and hanging components to vertically fix the circuit board. Combining corrosion-resistant materials and a sealing structure, it ensures uniform salt spraying and prevents leakage. A liquid pump and a spray pipe are used to simulate the salt spray environment, collect the liquid, guide it, and discharge it periodically.

Benefits of technology

This technology enables full exposure of the circuit board surface to a salt spray environment, improving the accuracy of corrosion assessment, shortening test preparation time, extending equipment lifespan, and reducing maintenance costs.

Abstract

The utility model belongs to test device technical field especially a circuit board testing device, aim at when carrying out salt mist test, circuit board is inconvenient to fix, the problem that horizontal placement is easy to influence back test effect, present and propose following scheme, including sealed cabinet, the cabinet mouth place of sealed cabinet one side is rotatably installed with two sealed cabinet doors, the inner wall of sealed cabinet is fixed with two horizontal poles symmetrically, be provided with the hanging component for vertical circuit board on the horizontal pole, the top of sealed cabinet inner wall is fixed with liquid injection pipe through bolt. The utility model discloses through setting up hanging component to realize circuit board vertical fixation, avoid horizontal placement back and cabinet contact to cause the salt mist deposition uneven, ensure that test surface is exposed to salt mist environment completely, improve the accuracy of corrosion evaluation, and the clamping structure of U type card frame and the setting of holding rod, facilitate the batch installation and taking out of circuit board, shorten test preparation time.
