The distance between the edge of a conductor and the edge of a supported or unsupported hole.
The thickness of the conductor at any point chosen at random on the printed board, normally viewed from vertically above unless otherwise specified.
The average or minimum (as specified) distance between the adjacent edges of conductors on the same layer of a printed board.
The total conductive pattern formed upon one side of a single layer of base material.
The conductor width at the plane of the surface of the base material. See also: Conductor width.
The configuration or design of the conductive material on the base laminate. Includes conductors, lands, and through connections.
A thin sheet of metal that may cover one or both sides of the base material and is intended to form the conductive pattern.
A material to which metal particles (usually silver ) are added to increase electrical conductivity.
Any of the basic parts used in building electronic equipment, such as a resistor, capacitor, DIP or connector, etc.
(Primary side) The surface layer of a board on which most of the components are placed. Component side is also referred to as the top side (layer one-counting downwards) of the board.
A hole in a PCB through-which a component lead passes in order to be soldered or connected mechanically to the printed circuit and electrically to the conductive pattern. Synonym: mounting hole....
A software module that analyses and converts programs from a high-level language to binary machine codes.
In which materials can be mixed or brought into contact with no reaction or separation.
A solder connection that exhibits poor wetting and that is characterized by a greyish porous appearance.
The fractional change in dimension of a material for a unit change in temperature expressed in ppm/C.
Chip on board. Component packaging technology in which bare integrated circuits are attached directly to the surface of a substrate and interconnected to the substrate most often by means of microscop...
