In tech speak a printed circuit board is a board that mechanically support and electronically connects electronic components in devices.

Printed circuit board construction. There are three major types of printed circuit board construction. When the number of components becomes too much for a single sided board a double sided board may be used. Advanced circuits inc 2004.

These features are usually etched on sheet layers of copper and laminated onto layers of a nonconductive substrate. How to build a printed circuit board. It accomplishes this task through the use of conductive tracks pads and other features.

Single sided boards have the components on one side of the substrate. Single sided double sided and multi layered. Multi layer construction the basic materials needed to build a multi layer board are copper.

Printed circuit boards were introduced to reduce the size weight and cost of parts of the circuitry. Even as circuit boards became available the point to point chassis construction method remained in common use in industry such as tv and hi fi sets into at least the late 1960s.
