A net is a junction of component nodes. A netlist is a collection of nets that define all the connections in a circuit. It is obtained automatically from a schematic capture program.
A resist which is polymerized (hardened) by light and which, after exposure and development remains on the surface of a laminate in those areas which were under the transparent parts of a production ,...
An artwork, artwork master, or production master in which the intended conductive pattern is transparent to light, and the areas to be free from conductive material are opaque.
The flared condition of copper on the inner conductor layers of a multi-layer board usually caused by hole drilling.
A production master used in the process of making two or more printed boars simultaneously.
Printed circuit boards consisting of three or more conducting circuit planes separated by insulating material and boned together with internal and external connections of the circuitry as required.
An enclosure that is located between the heating elements and the parts being processed that contains the atmosphere required for the re-flow soldering process.
A hole used for the mechanical mounting of a printed board or for the mechanical attachment of components to the printed board .
Also called back plane, or matrix board. A relatively large printed circuit board on which modules, connectors, sub-assemblies or other printed circuit boards are mounted and inter connections made by...
A component mounting technology that uses both through-hole and surface-mounting technologies on the same packaging and interconnecting structure.
The lack of dimensional conformity between successively produced features or terns.
A defect which is not likely to reduce the usability of the unit for its intended purpose, It may be a departure from established standard having no significant bearing on the effective use or operati...
The minimum allowable distance between adjacent conductors that is sufficient to prevent dielectric breakdown, between the conductors at any given voltage.
One thousandth (0.001) of an inch. Not to be confused with Mil (short for millimetre).1Inch=25.4mm; 1mil=0.0254mm.
A type of transmission line configuration which consists of a conductor over a parallel ground plane, and separated by a dielectric.
