Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-4, an integrated circuit current tester for a high-precision smart phone comprises a box body 1, a drying filter plate 11 and a circulating air exchange device 8, wherein a current tester 2 is arranged in the box body 1. The current tester can be any conventional current tester model on the market.

The drying filter plate 11 divides the box body 1 into an upper cavity and a lower cavity, the current tester 2 is arranged in the upper cavity of the box body 1, and the circulating air exchange device 8 is arranged in the lower cavity of the box body 1; a circle of drying blocks 13 are embedded in the inner wall of the upper cavity of the box body 1; the mode through embedding dry piece can practice thrift a large amount of drying costs, uses for a long time moreover, when needing the replacement dry piece, only need take out this round dry piece, the dry piece of replacement new can. The circulation trades wind device 8 and includes air-supply line 9 and draught fan 10, and the inner wall of the lower cavity of box is passed to the one end of air-supply line 9, and the other end links to each other with draught fan 10, and the air outlet of draught fan 10 is towards dry filter plate 11, be equipped with on the dry filter plate 11 and strain wind hole 12. A filter screen 91 is arranged at an air inlet port of the air inlet pipe 9, a semicircular blocking cover 93 is arranged on a mesh 92 of the filter screen 91, and the blocking cover 93 is arranged on the upper portion of the mesh.
