Picosun’s ALD nanolaminates improve lifetime and reliability of electronic circuit boards
ESPOO, Finland, 24th October, 2017 – Picosun Oy, leading provider of advanced Atomic Layer Deposition (ALD) solutions for global industries, has invented an ALD-based method(*) with which the operational lifetime and reliability of printed circuit board assemblies (PCBA) can be efficiently improved. Metal whisker formation and corrosion are some key factors that cause PCBA performance degradation over time. Metal whiskers are thin filaments or threads growing out from solders, components, and interconnects on the PCBA, and they can cause short-circuiting that leads to a system failure.
