紹介
With the widespread promotion of LED applications, the requirements for its reliability are becoming higher and higher. The LED reliability test is to evaluate the stability and reliability of the product in a specific environment and use conditions. For LED products, we mainly focus on the lamp bead life, heat resistance, light decay, impact resistance and environmental adaptability and other indicators of the test and evaluation.

Under salt fog chamber that we usually refer to relevant national and industry standards to ensure the accuracy and comparability of test results. for example:
GB/T 10125のISO 9227の人工的な大気の腐食テスト塩水噴霧の腐食
ASTM B117米国標準塩水噴霧試験
GB / T 2423.17、IEC 60068-2-11電子製品の塩水噴霧試験
GB / T 2423.18、IEC60068-2-52電子機器交互塩水噴霧試験
Salt spray test: the LED sample is exposed to salt spray environment, simulate the use scenario in the Marine environment, by observing the change of its surface corrosion, electrical performance changes and other indicators, to evaluate its reliability in a strong corrosion environment.
人工模擬塩水噴霧試験の分類:
(1) Neutral salt spray test (NSS test)
It is the earliest and most widely used accelerated corrosion test method. It uses 5% sodium chloride brine solution, the PH value of the solution is adjusted in the neutral range (6.5~7.2) as a spray solution. The test temperature is set at 35℃, and the settlement rate of salt spray is required to be between 1-2ml/80cm2(h).
【 Neutral salt spray test is the most commonly used test method. If no special instructions are made, the salt spray test we talk about usually refers to the neutral salt spray test 】

(2) Acetate spray test (ASS test)
It is developed on the basis of the neutral salt spray test.
It is to add some glacial acetic acid in 5% sodium chloride solution, so that the PH value of the solution is reduced to about 3.1-3.3, the solution becomes acidic, and the salt spray finally formed is also from the neutral salt spray into acid.
(3) Copper accelerated acetate spray test (CASS test)
It is a rapid salt spray corrosion test recently developed abroad. The test temperature is 50℃, and a small amount of copper salt - copper chloride is added to the salt solution to strongly induce corrosion.

(4) Alternating salt spray testIs a comprehensive salt spray test
It is actually a neutral salt spray test plus constant wet heat test.
It is mainly used for cavity type machine products, through the penetration of tidal environment, so that salt spray corrosion is not only produced on the surface of the product, but also produced inside the product. It is the alternating conversion of the product in the salt spray and wet and hot two environmental conditions, and the final examination of the electrical and mechanical properties of the whole machine product.
