1、 Preparation before film testing

Before conducting thin film testing, it is necessary to prepare the necessary thin film samples for the test. The selection of samples should be determined based on experimental requirements and purposes to ensure that the quality and specifications of the samples meet the testing requirements. At the same time, it is necessary to pre-set and adjust the constant temperature and humidity test chamber to ensure the stability and accuracy of the testing environment.

1. Preparation of thin film samples

Select appropriate thin film samples according to experimental requirements. Ensure that the sample surface is clean, free of stains, and that the size and shape meet the testing requirements. If pre-treatment of the sample is required (such as cleaning, drying, etc.), corresponding operations should be carried out before testing.

2. Setting of constant temperature and humidity test chamber

Before testing, it is necessary to set parameters such as temperature, humidity, and time for the constant temperature and humidity test chamber. According to the experimental requirements, adjust the temperature to the desired value and ensure stable humidity. At the same time, set the testing time so that the testing will automatically stop after reaching the predetermined time.

2、 Precautions during thin film testing process

When conducting thin film testing, it is important to pay attention to the following aspects to ensure the accuracy and reliability of the test.
