Electronic module with embedded jumper conductor
View Patent ↗The present invention generally provides a novel method for manufacturing an electronic module with crossed conducting lines and a novel electronic module with crossed conducting lines. In particular, an aspect of the present invention is to provide a thin, single layer electronic module. It is also an object of the present invention to provide an electronic module with an embedded jumper element having reliable high quality connections and contacts. To achieve at least some of the aspects of the present invention, an embedded pre-fabricated jumper module is placed inside a printed circuit board which allows the crossing of conducting lines within the module without manufacturing additional layers over the whole PCB board. The resultant PCB will have improved contacts and will not have surface deformation.

a wiring layer supported by a first substrate and having multiple conducting lines,
a component at least partially embedded in the first substrate with more than one contact terminal electrically connected to the conducting lines of the wiring layer,
a jumper element, at least partially embedded in the first substrate at a position separated from the component by the first substrate, having a second substrate supporting at least one jumper conductor, and
the at least one jumper conductor electrically connected to the wiring layer and positioned to allow the path of at least one conducting line to cross the jumper conductor without contacting the jumper conductor.
2. An electronic module according to claim 1 , wherein the jumper element is embedded in the first substrate such that it does not protrude from any surface of the electronic module.
3. An electronic module according to claim 2 , wherein there is a portion of the first substrate between jumper conductor and the crossing conducting line of the wiring layer which prohibits contact between the two.
