Abstract
Disclosed is a noise shield type multi-layered substrate which is advantageous in terms of shielding leaked magnetic flux and cross-talk by disposing a magnetic material onto at least one of circuit patterns, passive components and active components, thus blocking noise generated from the circuit patterns, passive components and active components. Thus, malfunctions of neighboring circuit patterns and various parts due to leaked magnetic flux are prevented. A method of manufacturing the noise shield type multi-layered substrate is also provided.
Claims22
A multi-layered substrate, comprising:
- a first substrate;
- a second substrate layered on the first substrate;
- a circuit pattern printed between the first substrate and the second substrate;
- and
- a magnetic material imbedded in at least one surface of a top and a bottom of the circuit pattern to provide a noise shield.
A multi-layered substrate, comprising:
- a first substrate;
- a second substrate layered on the first substrate;
- a passive component mounted between the first substrate and the second substrate;
- and
- a noise shield for limiting magnetic fields and including a magnetic material imbedded in one of said substrates adjacent to one of one surface of a top and a bottom of the passive component.
A type multi-layered substrate, comprising:
- a first substrate;
- a second substrate layered on the first substrate;
- an electric component mounted between the first substrate and the second substrate;
- and
- a magnetic material imbedded in at least one of said first and second substrates and disposed on at least one surface of a top and a bottom of the electric component mounted between the first substrate and the second substrate, said magnetic material forming a noise shield for said electric component.
