Electronics: Difference between revisions

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" />
