Major developments in technology Flashcards
Timeline of the development of microelectronics
19th century : batteries and basic lights and motors
early 20th century: Vacuum tube / thermionic values (lightbulb shaped electronics which acted as early transistors)
1940s : transistors and semiconductors
1960s : micro integrated circuits (contained hundreds of transistors)
1980s: Ultra large scale IC’s (1,000,000 + transistors)
2017: super computers w/ 1x10^10 transistors
Microelectronics (definition)
miniature electronic components that build up integrated circuits (IC’s)
Impact of microelectronics on design research
internet supplies massive amount of information quickly , photos and diagrams can be shared and edited instantly helping inform design
more people can be accessed during primary research
Impact of microelectronics on generating ideas
CAD, graphic tablets , easily accessed parts libraries, 3D rendering
Impact of microelectronics on design collaboration and communication
web conferences, email, cloud based file storage, online instantaneous collaboration
Impact of microelectronics on modelling and testing
Computer modelling ,rapid prototyping (3D printing), finite element analysis, complex computer simulations
Impact of microelectronics on manufacturing
CNC machinery, robotic manufacturing, JiT systems, 3D printing/ laser cutting
Impact of microelectronics on Quality Control
Automatic scanning, digital imaging, NDT with computer annalysis
the internet of things (IoT)
networks of linked electronic devices that communicate and work together to improve efficiency
Electro-hydraulic forming (description)
a shockwave from an electrical spark in a water bath forces sheet material over a former
Electro-hydraulic forming (properties)
uses a one sided former instead of the two part mould for die casting or drop forging which lowers tooling cost
very fast
high precision on complex detail
material is evenly distributed
Electro-hydraulic forming (applications)
electrical appliance cases
car parts
Advanced 3D printing using direct metal laser sintering [DMLS]
laser based metal 3D printing
laser fuses metal particles together layer by layer to print a fully metal component
Fibre injection moulding (description)
injection moulding will carbon fibre or glass fibre pellets filled with polymers such as polyamide [nylon]
Fibre injection moulding (properties)
strong still parts are made
very light weight products
reuses carbon fibre waste from CFRP
