The thermal shock chamber equipment can well detect various properties of electronic components in a rapidly changing temperature environment. Now many materials are tested by this equipment. Before the test chamber is operated, in order to make the test results of the equipment more accurate, in fact The test piece needs to be cleaned. Are there any precautions when cleaning the test piece?
The debris and dust on the test piece can be removed by cleaning. These accumulated dust may affect the test effect of the object. When cleaning, pay attention to cleaning the surface of the test piece and other substances on it. Do not use tape during cleaning. Corrosive substances.
Specimens can be cleaned by using a clean soft brush or ultrasonic cleaning device and hydrocarbons boiling between 60°C and 120°C. Rinse with unused solvent followed by washing to allow the sample to dry.
Before the test in the thermal shock chamber, some samples with a protective organic film layer cannot be cleaned or coated, and if they are samples cut from large and coated workpieces, they cannot be cleaned or coated. Damage the overlay near the cut area to avoid confusion.
After cleaning the sample, the staff should cover it with a cover such as a cover to avoid contamination of the sample by accidental contact and affect the detection effect.
After cleaning the test piece, it can be placed in the thermal shock test box. When placing the sample, pay attention to the placement position and material interval. This is because the test equipment has two-box and three-box types with different structures. The equipment requires the same placement of the test pieces, and considering the problem of heat dissipation, it is necessary to ensure that multiple test pieces are not too densely packed, and at the same time, keep a distance from the inner wall of the equipment, which is also convenient for air circulation in the box, to make the whole test operation more process.
We have introduced the cleaning of the cold and thermal shock chamber specimens here. If you want to know more about this type of equipment, you can continue to pay attention to us.
