Service Background
Natural environments contain abundant corrosive elements like sulfur and halogens. Environments strongly correlated with automotive applications, including roads, parking lots, and areas near sewers, are particularly prone to the accumulation of automotive exhaust fumes and marsh gas.
Electronic products utilize materials containing significant amounts of reactive metals such as silver, copper, and aluminum. Examples include: resistor silver electrodes, LED silver reflective layers, IGBT substrate copper layers, PCB copper layers, microwave/RF component silver solder layers, integrated circuit chip PAD aluminum layers, etc.
These metals readily react with strongly oxidizing elements like sulfur and halogens, forming compounds like silver sulfide, cuprous sulfide, and aluminum fluoride. This can lead to failures in microscopic areas of electronic components, such as open circuits, short circuits, and leakage currents.
Therefore, for electronic products, especially those used in automotive applications, sealed network communication environments, and electrical industry applications, conducting relevant corrosion verification is crucial. It confirms whether the product structural design, conformal coating protection, etc., meet specific lifetime requirements.
Our Advantages
GRGTEST has conducted extensive sulfur corrosion and electronic fluorinated coolant corrosion characterization tests for products within the supply chains of major domestic automotive manufacturers, as well as for communication base station and server products. Concurrently, we have performed in-depth research on accelerated corrosion life verification tailored to real-world application scenarios. This has allowed us to accumulate substantial verification experience and a wide array of testing equipment and instruments.
