PCB board incorporating thermo-encapsulant for providing controlled heat dissipation and electromagnetic functions and associated method of manufacturing a PCB board
First Claim
1. A circuit board assembly, comprising:
- a substantially planar shaped printed circuit board having a first side and a second side separated by a determined thickness;
at least one electrically operable component secured to a selected one of said first and second sides, said component generating at least one of a thermal flow pattern and an electromagnetic field; and
a three-dimensional encapsulant molded around said printed circuit board and substantially embedding said electrically operable component, said encapsulant providing selective heat conductive management of said thermal flow pattern and electromagnetic management of said electromagnetic fields generated by said component.

Abstract
A circuit board assembly includes a substantially planar shaped printed circuit board (PCB) having a first side and a second side separated by a determined thickness. At least one electrically operable component, typically an LED element, is secured to a selected one of first and second sides of the PCB board, the component generating at least one of a thermal flow pattern and an electromagnetic field. A three-dimensional encapsulant is in-molded around the printed circuit board in such a fashion as to substantially embed the electrically operable component. The encapsulant provides selective heat conductive management of the thermal flow pattern and electromagnetic management of the electromagnetic fields generated by the component.
