Electronic packaging is a rapidly developing technology affecting every aspect of human endeavor. The explosive growth in consumer and mobile wireless communication appliances is attendant with an ever-increasing demand for faster, smaller, cheaper, and better products. Increasing functionalities are being incorporated into information processing devices more than ever before. Wireless personal communication devices are expected to witness increasing use.
Every few years several electronics industry associations such as the Semiconductor Industry Association (SIA), NEMi, EIA, JPCA, IPC, etc., regularly publish roadmaps for the industry. Technologies are identified as conventional or threshold and advanced or leading edge technologies. Conventional and threshold technologies represent 90% of the products (about 60% conventional and 30% threshold technologies), and the rest is represented by leading edge. Usually, leading edge technologies cost about 60–80% premium in price. The roadmaps indicate the new technologies and their attributes and where they are headed in the coming years.
Technologies can be classified as sustaining technologies and disruptive technologies. Established technologies that advance in an incremental fashion are termed sustaining technologies and most fall under that category. Semiconductor technology migrating to finer and finer nodes and feature sizes to pack more functions per unit area, 0.5 mm (20 mil) pitch packaging, etc., to improve packaging density are examples of sustaining ones. On the other hand, technologies that unexpectedly replace well-established existing ones and improve product and services in a manner that the industry does not anticipate are termed disruptive technologies. Sometimes, they can be threatening to the existing infrastructure and can also dominate the marketplace. Examples of disruptive technologies include digital photography replacing traditional film photography, minicomputers displacing some mainframe computers, desktop publishing taking over traditional publishing, etc. Also, when traditional and established technologies reach their technological limits, paradigm shifts are needed for technology advancement. Also, disruptive technologies generally emanate from unexpected sources requiring fresh approaches in implementation.
