Electronic components are often susceptible to deterioration by environmental effects. Several studies have been reported on atmospheric corrosion of electronic devices with focus on functionality, storage capacity, and their miniaturization. However, there is a lack of studies focused on identifying the components most susceptible to atmospheric corrosion, the corrosion products generated in them, and the possible variables that have a greater impact on deterioration. The present study is focused on linking the deterioration of electronic boards with temperature and humidity cycles. This was accomplished through accelerated tests inside an atmospheric chamber, where the concentrations of pollutant gases (NO₂ and SO₂) are kept constant. Each trapezoidal cycle within the accelerated tests equals one day of field exposure. The results show that the NO₂ and SO₂ gasses reduced the life of the electronic components by 49.8%. The SO₂ gas was found to be the contaminant gas that most influenced the deterioration of electronic devices. Energy-dispersive spectroscopy (EDS) show the formation of CuSO₄. The development of protective coating against these pollutant gasses could improve the operation of electronic components.

电子元件通常容易受到环境影响而劣化。据报道，对电子设备的大气腐蚀进行了多项研究，重点是功能，存储容量及其小型化。但是，缺乏研究来确定最容易受到大气腐蚀的成分，其中产生的腐蚀产物以及对变质有较大影响的可能变量。本研究的重点是将电子板的劣化与温度和湿度循环联系起来。这是通过在大气室内进行加速测试来实现的，其中污染物气体（NO ₂和SO ₂）保持不变。加速测试中的每个梯形周期等于一天的野外照射。结果表明，NO ₂和SO ₂气体使电子元件的寿命缩短了49.8％。发现SO ₂气体是最影响电子设备劣化的污染气体。能量色散光谱法（EDS）显示了CuSO ₄的形成。开发针对这些污染物气体的保护涂层可以改善电子组件的运行。
