The 33rd William Blum Lecture, Electrochemical Technology in Electronics: Past Accomplishments and Future Challenges

Electrochemical technology has had a strong impact on development of the electronic industry. Were it not for electrochemical technology, components such as multi-layer PC boards, with recessed vias and through-holes, or contacts and connectors with curved surfaces, could not have been manufactured in the forms we know today. The ability to selectively plate metal films through polymer masks made possible fabrication of thin-film heads; these permitted much higher disk and tape storage densities than originally anticipated. Disk aerial densities of 200 mb/in2 are becoming commercial, while laboratory experiments with thin-film heads and thin-film disks have demonstrated that 1 and 2 Giga-bits per in2 are possible.
