Why are circuit boards green?Printed circuit boards first began being developed in the early 1900s. The earliest versions were constructed by just simple wires that connected components together by a series of pegs or “posts”. This was very unreliable as these connections would often crack and degrade over time. As techniques improved manufacturers needed a non-conductive yet durable substrate with which to lay the copper conductive traces upon. One of the cheapest solutions was fiberglass that was bonded with a glass reinforced epoxy-resin, and since this glass natural color is…
