The PCBA: The heart of the communication age

Printed circuit board technology enables modern communication.

In describing the extraordinary times in which we live today many terms are used. These include the Space Age, Atomic Age, Digital Age, Information Age, or Industry 4.0. All of these would be correct; however, the Communication Age is probably more accurate. The ability to communicate or send and receive meaningful information is critical in virtually all aspects of life today. And PCBAs are the mechanisms by which we are able to communicate most effectively.

The building of PCBAs or assembled printed circuit boards also depends upon accurate communication between the board designers, vendors, fab houses, and assemblers involved in the process. Let’s take a look at some of the most commonly used printed circuit board abbreviations and symbols that form the language.
