Important indicators of cleanliness testing equipment

The cleanliness detected by the cleanliness testing equipment is a very important quality management indicator. Industries that require strict cleanliness of parts include aerospace, semiconductor equipment, data storage, medical equipment, communications equipment, and more.

Cleanliness refers to the amount of contamination that remains on the surface of a part or product with a certain problem after data cleaning. The cleanliness is generally divided into the cleanliness of the product and the cleanliness of the parts. The product is assembled from various parts, so the cleanliness of the product is closely related to the cleanliness of the parts.

The measurement index parameters of pollutants mainly include product type, quantity, size, shape, weight, etc. The key indicators of each product are not necessarily the same, depending on the requirements of the indicators for product quality and cleanliness control accuracy.

At present, the research methods of cleanliness detection generally include contact angle method, weighing method, visual inspection method, particle size quantitative method, fluorescence luminescence method, and gravimetric method.
