Chapter 18. Printed Circuit Boards (PCBs)
Not Much Fun
Electronic components are rarely useful in isolation, and it is usually necessary to connect a number of them together in order to achieve a desired effect. Early electronic circuits were constructed using discrete (individually packaged) components such as transistors, resistors, capacitors, and diodes. These were mounted on a nonconducting board and connected using individual pieces of insulated copper wire. The thankless task of wiring the boards by hand was time-consuming, boring, prone to errors, and expensive, and it was generally agreed that this wasn’t much fun.
