Advantages of non-silicone thermal interface materials

Prevention of contact failure using low molecular weight siloxane!

In relays and switches used in electronic components, contact failure due to low molecular weight siloxanes is a concern. It is said that contact failure caused by low molecular weight siloxanes occurs when unreacted components or degradation products in silicone-based materials gasify and adhere to the relay contacts, and then oxidatively decompose into silicon dioxide (SiO2) due to the energy during relay operation, leading to accumulation. In recent years, as electronic components have become smaller and lighter, the volume of packaging has been decreasing, which has increased the risk of contact failure due to rising gas concentrations. Cosmo's thermal insulation materials do not contain silicone-based substrates, so there is no concern about contact failure due to low molecular weight siloxanes. They can be safely used in compact and high-density mounted electronic components. [Causes of electrical contact failure] - Dust in the air - Corrosion (sulfidation) on silver contacts - High concentration vapors of organic compounds - Vapors in silicone products (low molecular weight siloxanes)
