Definitions
Printed Circuit Board (PCB) Also known as a Printed Wire Board (PWB).
•
A device used to mechanically ponents while providing electrical
interconnection via a transmission line. It consists of one or more layers of
an insulating material and one or more layers of a conductive foil.
land The part of a PCB trace allocated for the connection to ponent.
•
via A hole in the PCB with conductive plating on the inside and which con-
•
nects to one or more condutive layers.
Through-hole Technology (THT) “Standard” ponents which are
•
mounted by inserting the leads into vias and then filling the vias and sur-
rounding land/pad with solder.
Surface-mount Technology (SMT) ponents which are soldered
•
directly onto the lands located on the surface of the PCB.
