“…In order to simulate controlled indoor conditions, the chamber was fabricated with precoated aluminum with a total volume of 0.1 m 3 and conditioned with two air inlet blinds coupled to metallic filters in order to permit the penetration of gases with the flow of air, to prevent the penetration of dust, and to avoid mistakes in the weight loss calculations [13,14]. The chamber was provided with metallic internal supports to hold the specimens; it was installed on the roof of an electronics manufacturing plant at 10 m above ground level [15,16].…”

Hydrogen sulphide (H2S) is considered one of the most corrosive atmospheric pollutants. It is a weak, diprotic, reducing acid, readily soluble in water and dispersed into the air by winds when emitted from natural, industrial, and anthropogenic sources. It is a pollutant with a high level of toxicity impairing human health and the environment quality. It attacks copper forming thin films of metallic sulphides or dendrite whiskers, which are cathodic to the metal substrate, enhancing corrosion. H2S is actively involved in microbially influenced corrosion (MIC) which develops in water, involving sulphur based bacteria, in oxidizing and reducing chemical reactions. H2S is found in concentrated geothermal brines, in the atmosphere of geothermal fields, and in municipal sewage systems. Other active atmospheric pollutants include SOX, NOX, and CO. This investigation reports on the effects of H2S on copper in microelectronic components of equipment and devices, with the formation of nonconductive films that lead to electrical failures.

The efficient control in the manufacturing control is very essential to increase the productivity and some specialized devices are made with and adequate functions. These devices are MEMS (Micro Electromechanical Systems), which are low-power microdevices widely used in the industrial processes of the Mexicali aerospace industry, which have the function of controlling the operation of industrial systems at any stage of manufacturing by evaluating the way to carry out their activities, comparing standardized values with data real and activate and deactivate high power actuator mechanisms such as fans, motors, electric pumps and other high power used in this installed industry. These microdevices have specific characteristics in their operation to obtain the best operational performance of industrial equipment and machines, at a low cost and partially operating according to the operating system reference values of industrial systems and generating a safe process in their operation. The industrial processes of the Mexicali aerospace industry require specialized knowledge because they manufacture components with very rigid operations because they are manufactured for aircraft with very rigorous regulations, due to the high security that air transport requires. MEMS have increased their use in the last ten years, where it has been applied to various industries due to the simple way of coupling with industrial systems, and this is why research was conducted to evaluate its use in a company in this city that they did not intend to use them and when observing that they increased their productive performance at one stage of their industrial processes, they chose to apply them in all their manufacturing areas. The investigation was from 2018 to 2019.
