Embodiment 1

[0017] A simple detection method for clean room accessories, comprising the following steps:

[0018] 1) Choose clean and pollution-free glass, drop 1-2ml of freshly evaporated analytical pure alcohol on the glass, after the alcohol volatilizes, take pictures with an optical microscope, and build a block; drop the glass on the edge of the material to be tested Add 1-2ml of newly distilled analytical pure alcohol, soak the tested material onto the glass and take away the tested material; after the alcohol volatilizes, observe the amount of non-volatile residues on the edge and center respectively through an optical microscope;

[0019] 2) Compare the non-volatile residue of the tested material observed under the optical microscope with the non-volatile residue of the known qualified material measured under the same conditions, if the residue of the tested material is less than or equal to the qualified material The residues are determined to be qualified for the tested material...

Abstract

The invention provides a simple detecting method for auxiliaries in a cleaning room. The simple detecting method includes the following steps of firstly, selecting clean pollution-free glass, dripping 1-2ml of newly-distilled analytically pure alcohol on the glass, taking pictures by an optical microscope after the alcohol is volatilized and building a file; dripping 1-2ml of newly-distilled analytically pure alcohol at the edge of a detected material on the glass, impregnating the detected material on the glass and taking off the detected material; and respectively observing quantity of non-volatilized residues through the optical microscope after the alcohol is volatilized; and secondly, comparing non-volatilized residues of the detected material observed by the optical microscope with non-volatilized residues of a qualified material on the same condition, and judging the detected material to be qualified if the residues of the detected material is fewer than or equal to the residues of the qualified material. Accordingly, auxiliaries used on site are guaranteed to be qualified, possible harmful affection on production and product due to quality auxiliary quality fluctuation can be eliminated.

Description

Technical field: [0001] The invention relates to a method for inspecting materials in a clean room in OLED production, in particular to a simple detection method for clean room auxiliary materials. Background technique: [0002] In the OLED production process, the cleanliness of the clean room is highly required. Therefore, the auxiliary materials used on site, such as protective gloves, and dust-free cloths used for cleaning equipment and utensils, are also very demanding, otherwise the effect of protection and dust removal will not be achieved, and the product will be polluted. However, there is a lack of testing equipment and means for auxiliary materials on the production site. In the actual application process, the item standards provided by the supplier are not completely consistent with our actual application effect. Sometimes the purchased high-grade dust-free cloth, after wiping the Mask, the original pollution is removed, and the dust-free cloth brings new polluti...
