Key considerations in PCBA coatings

Sept. 22, 2023
In aerospace/space hardware, shock, vibration or harsh operating environment have the potential to impact component and/or solder joint integrity. Coatings represent one option to help mitigate the impact of those operating environment conditions.

While a robust manufacturing, test and inspection process can deliver PCBAs that meet industry workmanship standards, operating environment conditions can degrade components or solder joints over time. In aerospace and space hardware, shock, vibration or harsh operating environment have the potential to impact component and/or solder joint integrity. Coatings represent one option to help mitigate the impact of those operating environment conditions, protecting both components and their solder joints from the accelerated degradation that would otherwise occur. This whitepaper looks at the conformal coating process and key considerations in ensuring a quality outcome.
