Electronics: Difference between revisions

'''Electronic''' [[Electronic circuits|circuitcircuits]]s and [[Electronic component|componentcomponents]]s can be divided into two groups: [[analog]] and [[digital]]. In practice a device may consist of circuitry that has one or the other or a mix of the two.<ref name="we">[[Wikipedia:Electronics]]</ref>

In the 1950s and '60s experimenting with electronics was simpler but limited in what could be produced. These days it very much more sophisticated. However with the components and [[tools]] now available, a lot more can be achieved that back then would have taxed a huge research lab.<ref>''Build Your Own [[Printed Circuit Board]]'' by Al Williams, Tab, 2003, {{ISBN 9780071427838|978-0-07-142783-8}}</ref> One of the traditional paths to learning electronics is amateur radio.<ref>Embedded, [http://www.embedded.com/electronics-blogs/break-points/4370279/Ham-radio-today Ham radio today] by Jack Ganssle, 2 Apr 2012</ref>

Many different methods of connecting components have been used over the years. Early electronics often used point to point wiring, or [[terminal strips]]. Most modern day electronics now use [[printed circuit board]]s (PCBs) made of materials such as [[FR-4|FR4]], or the cheaper (and less hard-wearing) Synthetic Resin Bonded Paper (SRBP, also known as phenolic, Paxoline/Paxolin (trade marks) and [[FR-2|FR2]]). Health and environmental concerns associated with electronics assembly have gained increased attention in recent years, especially for products destined to the European Union, with its Restriction of Hazardous Substances Directive (RoHS) and Waste Electrical and Electronic Equipment Directive (WEEE).<ref name="we" />

An engineer or designer must balance many objectives and practical considerations when selecting [[enclosure]]s and protective features of the product itself and its components.<ref>[[Wikipedia:Electronic_packagingElectronic packaging#Design_considerationsDesign considerations]]</ref>
