Glossary of terms

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

Printed circuits

covers all kinds of mechanical constructions of circuits that consist of an insulating base or support carrying the conductor and are combined structurally with the conductor throughout their length, especially in a two-dimensional plane, the conductors of which are secured to the base in a non-dismountable manner, and also covers the processes or apparatus for manufacturing such constructions, e.g. forming the circuit by mechanical or chemical treatment of a conductive foil, paste, or film on an insulating support.

Printed circuits (assemblies of a plurality of individual semiconductor or solid state devices H01L 25/00; devices consisting of a plurality of solid state components formed in or on a common substrate, e.g. integrated circuits, thin-film or thick-film circuits, H01L 27/00)
Definition statement

This place covers:

Details of printed circuit boards [PCBs], use of materials for PCBs, printed elements for electrical connection to or between printed circuits, printed electric components, structural association of two or more PCBs, structural association of PCBs and non-printed electric components.

H05K 1/00 covers mainly structural aspects (incl. layout) of printed circuits and materials for printed circuits. However certain sub-groups of H05K 1/00 cover also the respective manufacturing aspects (e.g. H05K 1/16, H05K 1/185).

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).
