Printed circuit boards, or PCBs, are absolutely essential to the functioning of all electronic equipment from the simplest computer mouse to the vast computer arrays that power space programs. PCB manufacturing has come a long way since the very first such devices. Today’s pick and place machines, or SMT component placement systems, can precision place elements on a printed circuit board at high speed.
What is a Printed Circuit Board?
As its name suggests, this is simply a board made of an insulated material on which electrical circuits are laid in a particular order. The simplest printed circuit board has copper tracks that connect along only one layer and side of surface. The most complicated such boards can be printed on both sides or even in multiple layers of boards. The circuits on either side of the board or between the layers are connected through small holes punched in the insulated materials.
