Circuit Boards
10/21/2008
“A printed circuit board, or PCB, is used to mechanically support and
electrically connect electronic components using conductive pathways, or traces,
etched from copper sheets laminated onto a non-conductive substrate. It
is also referred to as printed wiring board (PWB) or etched wiring board. A PCB
populated with electronic components is a printed circuit assembly (PCA), also
known as a printed circuit board assembly (PCBA).

Notes
“PCBs are rugged, inexpensive, and can be highly reliable. They require much
more layout effort and higher initial cost than either wire-wrapped or
point-to-point constructed circuits, but are much cheaper and faster for
high-volume production. Much of the electronics industry's PCB design, assembly,
and quality control needs are set by standards that are published by the IPC
organization.”
