Problems solved by technology

However, due to the high humidity of the test environment of the existing test platform, when it is tested in a low temperature environment, the LED chip is prone to dew condensation or even freezing, which will affect the results of the electrical test. There is still room for improvement in technology

Embodiment Construction

[0030] Since the test platform with a dry environment provided by the present invention has too many combination implementations, it is not repeated here, and only three preferred embodiments are listed for specific illustration.

[0031] Please also refer to figure 1 as well as figure 2 , figure 1 A schematic diagram showing a test platform with a dry environment according to the first preferred embodiment of the present invention, figure 2 It shows a three-dimensional cross-sectional schematic view of the bearing seat and the flow guiding mechanism of the first preferred embodiment of the present invention. As shown in the figure, the test platform 1 with a dry environment provided by the first preferred embodiment of the present invention is used to test a wafer to be tested (wafer) with a light emitting diode (LightEmittingDiode; LED) chip. Of course, in other implementations In the example, other objects to be tested can be tested and are not limited to the above, wh...

Abstract

A test platform with a dry environment comprises a bearing seat, a flow guiding mechanism and a drying air generating device. The bearing seat comprises a testing area, the flow guiding mechanism surrounds the bearing seat, the drying air generating device is connected to the flow guiding mechanism to generate drying air, and the drying air is guided by the flow guiding mechanism to flow to the testing area, so that the dry environment is generated, and moisture condensation is avoided.

Description

technical field [0001] The invention relates to a test platform with a dry environment, in particular to a test platform which uses a flow guiding mechanism to guide dry gas to a test area to generate a dry environment. Background technique [0002] With the development of science and technology and the progress of the times, people's awareness of environmental protection has risen and the concept of environmental protection has improved. Energy saving and carbon reduction have become an issue and goal that countries around the world attach importance to. As well as high-pressure sodium lamps, they are gradually replaced by Light Emitting Diode (LED) lamps. LED lamps are not fragile, save electricity, are environmentally friendly and mercury-free, have a directional light source, are small in size, and have a rich color gamut. They can be used in low temperature environments and cause light Because of the advantages of less damage and long working life, LED will widely and r...
