ESPOO, Finland, Oct.
24, 2017 /PRNewswire/ --
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. This is particularly fatal in several
sensitive applications such as medical, automotive, space,
aviation, military, and industrial control electronics.
Previously, lead has been added to solder alloys to prevent
whisker formation, but the current environmental regulations
prohibit its use. This is why novel methods, such as the ALD-based
surface protection technique developed and now industrially enabled
by Picosun are very much sought after amongst the electronics
manufacturers. In Picosun's approach, application-specifically
tailored ALD nanolaminate forms a dense, conformal, and hermetic
seal on the PCBA. This seal protects the PCBA components from the
corrosion caused by moisture and impurities in the ambient air and
blocks the metal whisker propagation. As ultra-thin films, ALD
coatings have the additional benefit of allowing postprocessing of
the PCBA, and they do not increase its mass or dimensions.
Furthermore, as a gas-phased technique, ALD is gentle to the
surface, it can be applied at moderate temperatures, and it is
environmentally friendly.
"Our PCBA protection technology has gained lots of interest
amongst our clients both in industries and in R&D, and many are
eager to start applying it in their manufacturing processes.
Electronic circuit board industry is a vast, global market, where
we are happy to utilize our ALD knowhow to enable products of
extended lifetime and improved safety and reliability. Our
comprehensive selection of industrial ALD systems guarantees an
optimal solution to every customer, allowing fast and economic
processing of even large area PCBAs in just one process run,"
states Juhana Kostamo, Managing
Director of Picosun.
Picosun provides the most advanced ALD thin film coating
technology to enable the industrial leap into the future, with
turn-key production solutions and unmatched expertise in the field.
Today, PICOSUN™ ALD equipment are in daily manufacturing use in
numerous major industries around the world. Picosun is based in
Finland, with subsidiaries in
Europe, North America, Singapore, Taiwan, China, and Japan, and a world-wide sales and support
network. For more information visit www.picosun.com.
