Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is described in further detail.
It should be noted that in following specific embodiments, when embodiments of the present invention are described in detail, in order to clear
Ground represents structure of the invention in order to illustrate, spy, not according to general scale, and has carried out part to the structure in accompanying drawing
Amplifying, deform and simplify treatment, therefore, should avoid being understood in this, as limitation of the invention.
In specific embodiment of the invention below, Fig. 1 is referred to, Fig. 1 is one kind of a preferred embodiment of the present invention
High precision temperature control resistance test system structure principle chart.As shown in figure 1, a kind of high precision temperature control resistance test system of the invention
System, at least including example platform, heater, infrared imaging hygrosensor, several major parts such as probe.
Refer to Fig. 1.Example platform is used to place test sample, for example, can be testing sample silicon chip;The sample is put down
