Electronic Pack….. Chapter 1 Slide 3 Definition of ELECTRONIC PACKAGING "The realization of the physical, electronic system, starting with block- /circuit diagram” –Involves choice of technology for implementation, choice of materials, detailed design in chosen technology, analysis of electrical and thermal properties, reliability. – This definition is one among many, and may shift as the field is further developed.
Electronic Pack….. Chapter 1 Slide 4 Multidisciplinary Requires combination of many disciplines: –Electronics –Materials properties and materials compatibility –Mechanics –Chemistry –Metallurgy –Production technology –Reliability, etc. Product development should involve experts from the various fields, and the interdependence of the fields may be the most important to make a good product.
Electronic Pack….. Chapter 1 Slide 5 TYPES OF ELECTRONICS AND DEMANDS ON THEM - EXAMPLES Sattelite electronics –Production volume: one unit, 20 years life required, no repair, very low weight and power, very high development cost acceptable Life saving medical electronics –Similar reliability/power demand, may be in harsh environment (body fluids), medium production volume.
Electronic Pack….. Chapter 1 Slide 6 Examples, cont Telephone main switchboard –10 year life, benign environment, very high complexity, low and high production volume, high price pressure Military electronics –Very high reliability demands, in very rough environments. High development cost (and production cost) acceptable
Electronic Pack….. Chapter 1 Slide 7 Examples, cont Computers –High performance and reliability required. Very short product life, high production volume for some, small volume for some products Consumer products (watches, calculators...) –Extreme price pressure, very short product life, low weight, power, very big market. No repair.
Electronic Pack….. Chapter 1 Slide 8 Development Phases Market research –Gives product idea
Electronic Pack….. Chapter 1 Slide 9 DEVELOPMENT PHASES, continued Pre-study –Gives product suggestion Defining overall specifications –Gives definition of product, simulation/lab model of critical parts Prototype A –Main principles analysed, important parts implemented, technology chosen
Electronic Pack….. Chapter 1 Slide 10 DEVELOPMENT PHASES, continued Prototype B –Detailed design, correct form and components. Ready for industrialisation. Industrialisation –Prototype adapted to producability in available production equipment. New production line built if needed, pilot series made. –Marketing started, service planned –Full scale production –Product sale, maintainance, service
