• 17:0217:02, 23 April 2024 diff hist +308‎ N Glossary:Soak test ‎ Created page with "A soak test is an extended test of a device following manufacture or repair, with the aim of shaking out any manufacturing defects or shortcomings in the repair. Sometimes this will be performed at full power or in some other way designed to stress any weak components and precipitate any incipient failures." current
• 16:5516:55, 23 April 2024 diff hist +441‎ N Glossary:Bathtub curve ‎ Created page with "Reliability studies in many fields tend to show a common pattern for failures. Manufacturing defects are the principal cause of early life failures, but once these have all been shaken out the failure rate remains fairly low through the expected lifetime of a device. The failure rate then starts to climb as components begin to wear out. So plotting the failure rate against time gives a U-shaped curve, commonly known as the bathtub curve." current
• 15:2915:29, 23 April 2024 diff hist +172‎ N Glossary:Conflict Materials ‎ Created page with "Conflict materials are raw materials largely sourced from conflict regions, where their supply is likely to be used for the purchase of arms or the support of armed groups." current
• 15:2615:26, 23 April 2024 diff hist +247‎ N Glossary:Critical Raw Materials ‎ Created page with "CRM or Critical Raw Materials are those raw materials in critically short supply. This may be because there simply isn't much of them waiting to be mined, or because what there is is largely controlled by unfriendly or potentially hostile nations." current
• 15:2015:20, 23 April 2024 diff hist +168‎ N Glossary:Upcycling ‎ Created page with "Upcycling is the practice of taking disused or faulty items or their major components and reusing them in a different way, hence saving them from recycling or landfill."
• 15:1515:15, 23 April 2024 diff hist +298‎ N Glossary:Refurbishment ‎ Created page with "Reurbishment is the practice of taking used items and giving them a new lease of life by replacing worn or damaged parts, bringing them up to date with a fresh software installation and perhaps replacing a slow hard drive with a much faster SSD." current
• 15:0415:04, 23 April 2024 diff hist +241‎ N Glossary:Remanufacture ‎ Created page with "Remanufacture is the practice of creating good-as-new products using some proportion of pre-used parts. Common examples are ink and toner cartridges and laptop batteries, could equally include a laptop given a new case, keyboard and battery." current
• 14:5914:59, 23 April 2024 diff hist +379‎ N Glossary:Recycling ‎ Created page with "Recycling is the practice of recovering raw materials from waste items. This is generally inefficient and often impracticable or uneconomic for valuable materials used in small quantities. Furtthermore the resultant raw materials may not be of sufficient quality for demanding applications. Hence it is regarded as the second-worst option, ahead only of landfill or incineration."
• 14:5014:50, 23 April 2024 diff hist +248‎ N Glossary:Circular economy ‎ Created page with "A circular economy is one where a minimum of items or their parts are sent for landfill or incineration, and a high proportion are either reused, repaired or recycled, so minimising the consumption of raw materials and the pre-use carbon footprint." current
• 14:4514:45, 23 April 2024 diff hist +201‎ N Glossary:Repair ‎ Created page with "Repair is the second option (after reuse) in a circular economy. It has been shown that many devices sent for recycling could actually be repaired relatively easily and hence given a new lease of life." current
• 14:4214:42, 23 April 2024 diff hist +225‎ N Glossary:Reuse ‎ Created page with "Reuse is the preferred option in a circular economy. Many items are discarded because they have been replaced by a newer model, or simply fallen into disuse, but could be given a second life if sold or donated to a new owner." current
• 14:3614:36, 23 April 2024 diff hist +166‎ N Glossary:E-Waste ‎ Created page with "e-Waste is all those electrical and electronic goods discarded by their owner, whether because they are faulty, no longer needed, or simply replaced by a newer model." current

• 20:1420:14, 20 April 2024 diff hist +447‎ N Glossary:Gallium ‎ Created page with "Gallium is a soft metal similar to aluminium but with a low melting point. In electronics, many compounds of gallium are semiconductors with useful properties. Gallium arsenide devices are able to operate at much higher frequencies than their silicon counterparts and so are widely used in mobile phones and satellite comunications. Various other gallium compounds are used in practically all visible and infra-red LEDs." current
• 19:4819:48, 20 April 2024 diff hist +440‎ N Glossary:Silicon Carbide ‎ Created page with "Silicon carbide (as carborundum) has long been used as an abrasive, but it is also a semiconductor with useful properties for high power applications. In recent years silicon carbide devices such as MOSFETs having higher voltage and power ratings than equivalent silicon devices have been increasingly used in applications such as EVs and power conversion."
