Electronic products are related products based on electricity. The electronics industry includes:
Investment product industries, such as electronic computers, communication machines, radars, instruments and electronic special equipment, are the means of national economic development, transformation and equipment.
Electronic component products and special materials industry, including kinescopes, integrated circuits, various high-frequency magnetic materials, semiconductor materials and high-frequency insulating materials, etc.
Consumer product industries, including televisions, tape recorders, video recorders, etc, are mainly to improve people's living standards.
In the process of storage, transportation and use, electronic products are often affected by various harmful effects of the surrounding environment, such as affecting the working performance, reliability and life of electronic products. Environmental factors affecting electronic products are temperature, humidity, atmospheric pressure, solar radiation, rain, wind, ice and snow, dust and sand, salt spray, corrosive gases, mold, insects and other harmful animals, vibration, shock, earthquake, Collision, centrifugal acceleration, sound vibration, sway, electromagnetic interference and lightning, etc.
①Temperature (-73~180℃): high temperature, low temperature, temperature cycling, rapid rate temperature change, thermal shock etc, to check the storage and operation performance of electronic products (materials) in a hot or cold environment, and check whether the test piece will be damaged or its function degraded. Use temperature test chambers to test them.
②Temperature humidity(-73~180, 10%~98%RH): high-temperature high humidity, high-temperature low humidity, low-temperature low humidity, temperature humidity cycling, etc, to check the storage and operation performance of electronic products (materials) in temperature humidity environment, and check whether the test piece will be damaged or its function degraded.
③ Pressure (mbar): 300,000, 50,000, 10000, 5000, 2000, 1300, 1060, 840, 700, 530, 300, 200; to check the storage and operation performance of electronic products (materials) in different pressure environment, and check whether the test piece will be damaged or its function degraded.
④ Rain spray test(IPx1~IPX9K): simulate different degrees of rainy environment, to determine the rain-proof function of the sample shell, and examine the function of the sample when and after it is exposed to rain. Rain spray test chamber works here.
⑤ Sand and dust(IP 5x ip6x): simulate sand and dust environment, to determine the dust-proof function of the sample shell, and examine the function of the sample when and after it is exposed to sand dust.
①Salt fog: The chloride liquid particles suspended in the air are called salt fog. The salt fog can go deep from the sea to 30-50 kilometers along the coast with the wind. The amount of sedimentation on ships and islands can reach more than 5 ml/cm2 per day. Use Salt fog test chamber to do the salt fog test is to evaluate the salt spray corrosion resistance of the metal materials, metal coatings, paints, or coatings of electronic components.
②Ozone: Ozone is harmful to electronic products. Ozone test chamber simulates and strengthens the conditions of ozone, study the effects of ozone on rubber, and then take effective anti-aging measures to improve the life of rubber products.
③Sulfur dioxide, hydrogen sulfide, ammonia, nitrogen and oxides: In the chemical industry sector, including mines, fertilizers, medicine, rubber, etc., the air contains many corrosive gases, the main components of which are sulfur dioxide, hydrogen sulfide, ammonia, and nitrogen oxide, etc. These substances can form acidic and alkaline gases under humid conditions and damage various electronic products.
①Vibration: The actual vibration conditions are more complicated. It may be a simple sinusoidal vibration, or a complex random vibration, or even a sine vibration superimposed on random vibration. We use vibration test chambers to do the test.
②Impact and collision: Electronic products are often damaged by collision during transportation and use, bump test equipment for it.
③Free drop test: Electronic products will fall due to carelessness during use and transportation.
