associated with components encapsulated in the insulating substrate of the PCBs; associated with components incorporated in internal layers of multilayer circuit boards

Introduced: January 2026

Full Title

Full titles differ between systems:

IPC:

Printed circuits > structurally associated with non-printed electric components > associated with components mounted in printed circuit boards [PCB], e.g. insert-mounted components [IMC] > associated with components encapsulated in the insulating substrate of the PCBs; associated with components incorporated in internal layers of multilayer circuit boards

CPC:

Printed circuits > structurally associated with non-printed electric components (H05K1/16 takes precedence) > associated with components mounted in printed circuit boards [PCB], e.g. insert-mounted components [IMC] > associated with components encapsulated in the insulating substrate of the PCBs; associated with components incorporated in internal layers of multilayer circuit boards

Additional Content IPC
