Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

Printed circuits

The term covers all kinds of mechanical arrangements of circuits that consist of an insulating base or substrate, having at least one conductive layer permanently formed on the base. The base often extends in a two-dimensional plane. Other conductive layers may be formed in a layer structure within the base. The base may support components on its surface or between its layers. Each conductive layer is formed as separate patterns or tracks to connect the components as required. The term is also applied adjectivally to processes or apparatus for manufacturing such circuits, e.g. by mechanical or chemical treatment of conductive foil, paste, or film that has been applied to an insulating base, support, or substrate.

Printed circuits
Definition statement

This place covers:

  • Details of printed circuit boards [PCBs], e.g. structural aspects or use of materials for PCBs
  • Printed elements for electrical connection to or between printed circuits
  • Printed electric components in PCBs, e.g. resistors, capacitors or inductors formed by printing materials onto the board, or within its layer structure
  • Structural association of two or more PCBs
  • Structural association of PCBs and non-printed electric components, e.g. within internal layers
Relationships with other classification places

There is no clear boundary between the field of printed circuit boards and other more specific fields, e.g. inductors (H01F), antennas (H01Q), waveguides (H01P), chip cards (G06K 19/07), thin film and thick film circuits (H01L 27/00), other packaging levels (semiconductor packages H01L 21/48, H01L 23/00, H01L 25/00), connectors (H01R) and various electronic components. The materials and methods (deposition, patterning, connection, etc.) used for manufacture of printed circuit boards have their general fields.

Documents often contain information relevant to several technical fields and have to be circulated for classification in these fields, in particular to H01L (semiconductors) but also the other parts of H05K, H01R (connectors).
