Indium Corporation has published 35 technical articles, 24 blog posts, and 14 videos to help members of the global electronics assembly industry solve voiding challenges.

“Voiding is one of the most prevalent challenges facing electronics manufacturers today,” said Christopher Bastecki, Associate Director of Electronics Assembly Materials. “Indium Corporation has spent years conducting extensive testing on materials and procedures to reduce voiding levels. As a result, we provide one of the most extensive libraries in the industry on this subject.”
