Checking back on Tech Talk Nos. 100 and 200, which reflected on past and anticipated future changes in electronic packaging, I not- ed the production shift to Asia, followed by the relocation of the supplier base, and, more recently, the design of electronic devices. New mobile applications forced technology changes and shifted the economic viability of old and new companies. In a basically conservative in-
