96 SMT007 MAGAZINE I MARCH 2021 Future Use One of the criteria important in determining the requirements for the salvaged components is an understanding of how the components will be placed onto their next board. For exam- ple, if the components will be hand soldered in place, then co-planarity and amount of rem- nant solder le over on the component will be less than that of a component to be placed using automation. One of the final criteria is looking at the kind of component packaging that will be required. e components need to be placed into tape and reel packaging, tubes or trays, in order to deliver the salvaged components to manufac- turing operations. It is recommended that the components be marked (Figure 2) in some fashion to keep track of which components are going on to specific assemblies. By considering these criteria, the salvaging of electronic components from circuit boards will go smoothly.

The European Space Agency has given the green light to The Atmospheric Remote-sensing Infrared Exoplanet Large-survey, or Ariel as it's bet- ter known, the world's first space telescope dedi- cated to studying how exoplanet atmospheres form and evolve. Its mission is to understand the links between a planet's chemistry and its environment by charting approximately 1,000 known planets outside our own Solar System, arm- ing scientists with a full picture of what exoplanets are made of, how they were formed and how they will evolve. Ariel has been put through a rigorous review process throughout 2020, and is now slated for launch in 2029. Once in orbit, Ariel will rapidly share its data with the general public – inviting space enthusiasts and bud- ding astronomers to use the data to help select targets and characterise stars. The spectrographs aboard the observatory will study the light that filters through a planet's atmosphere as it passes—or transits—across the face of its host star. Instruments will also try to refine estimates of a plan- et's temperature by teasing out how light from its star changes when the body moves behind it. Ariel will be able to detect signs of well-known ingredients in the planets' atmospheres such as water vapour, carbon dioxide and methane. It will also detect more exotic metallic. For a select num- ber of planets, Ariel will also perform a deep survey of their cloud systems and study seasonal and daily atmospheric variations.
