Spaceworthy encapsulants from Picosun

Espoo, Finland | Posted on December 21st, 2015

ALD oxide nanolaminates developed by Picosun have been proven to efficiently protect printed circuit board (PCB) components from aging effects such as corrosion and tin whisker formation(*). Corrosion typically occurs on the interface between the board and the component. Gaps in the solder tin covering the sharp edges of the component’s conducting pins may leave them vulnerable against environmental factors such as humidity, liquid and gaseous impurities. This is particularly detrimental in several high end applications where unfaltering component performance is required, such as in aerospace electronics. ALD forms ultra-thin, hermetic, inert, flexible, and protective film over the whole board, isolating even the most sensitive points from the ambient conditions. Due to the nanometer-scale thickness, the ALD film has negligible impact on the PCB functionality.

“Production-scale processing of PCBs requires production-optimized ALD technology. Picosun has unmatched and the most comprehensive expertise in providing large scale ALD solutions to various industries, not only to semiconductor and IC manufacturing but also for protection of 3D items – coins, watch and jewelry parts, and medical implants being just a few examples. Expanding our business to PCB encapsulation is yet another example of ALD’s penetration throughout the spectrum of today’s industrial manufacturing”, states Juhana Kostamo, Managing Director of Picosun.

(*) The development and optimization work of ALD nanolaminate encapsulants for PCB protection has been carried out in Picosun’s contract project with the European Space Agency (ESA), coordinated by Technical Officer Mr. Jussi Hokka.

Picosun provides the most advanced ALD thin film coating technology to enable the industrial leap into the future, with high end 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 North America, China, Taiwan, Singapore, and Japan, and a world-wide sales and support network. For further information visit www.picosun.com

The Picosun-ESA contract is a part of an activity funded by the ESA programmes European Component Initiative Phase 4 and Strategic Initiative. Disclaimer: The views expressed herein can in no way be taken to reflect the official opinion of the European Space Agency.
