Chapter 3 p 81 – microsystem classes (4 of 6 discussed in chapter) and the role of packaging COMPUTER (high signal speed and electrical performance) TELECOM (high bandwidth) AUTOMOTIVE (harsh environment) CONSUMER & MEDICAL (compact, portable) p81 – microsystem categories six categories: automotive, computer and business equipment, communications, consumer, industrial and medical, military and aerospace p81 – electronic components can be a) active = consume power while delivering functionality to system b) passive = provide performance functions (connections, support, filtering, noise reduction) critical to active devices b1- passives can be broken down to PCB, switches & relays, connectors, resistors, capacitors, passive microwave components (filters, crystal oscillators) p82 – microsystem market in 2000 computer & biz = 38.6% ($383B) communications = 26.1% ($259B) consumer = 11.3% ($112B) industrial & medical = 10.6% ($105B) military = 8.7% ($86B) automotive = 4.8% ($48B) p82 – sub 0.1 micron enable higher switching speeds and greater functional density; move towards adoption of copper conductors (faster signal travel at lower power) and low dielectric constant insulators (faster signal travel through interconnect layer) p84 – cell phone packaging PWB = $33.5B connectors = $24B passive components = $18B active components = $12.6B switches & relays = $6B passive microwave components = $5B p85 – ENIAC first electronic numerical integrator and computer, with 18,000 vacuum tubes, designed by Presper
