Abstract
A circuit board assembly and a backlight module comprising the circuit board assembly are provided. The circuit board assembly has a first surface and a second surface opposite to the first surface, and further comprises at least one laminate, a first conductive wiring structure and a coating. The first conductive wiring structure is formed on the first surface. The coating is formed on the coating area of the second surface, wherein the coating can conduct heat and provide electric insulation. Thus, the circuit board assembly is adapted to outwardly conduct heat from the laminate through the second surface and to promote the heat dissipation efficiency of the circuit board assembly.
Claims20
A circuit board assembly, comprising:
- at least one laminate defining a first surface and a second surface opposite to the first surface, wherein the at least one laminate is formed with a through hole;
- a first conductive wiring structure formed on the first surface;
- a thermo-conductive structure formed in the through hole to conduct heat from the first surface to the second surface;
- a pad disposed on the first surface to substantially cover the through hole at a periphery thereof;
- and
- a coating at least formed on the second surface at a coating area thereof, wherein the coating is thermo-conductive and electro-insulating, and is adapted to outwardly dissipate heat from the at least one laminate through the second surface.
A backlight module, including:
- a bezel;
- a light source;
- and
- a circuit board assembly disposed on the bezel, the circuit board assembly including:
- at least one laminate defining a first surface and a second surface opposite to the first surface, wherein the second surface faces the bezel and the first surface is provided for the light source;
- a first conductive wiring structure formed on the first surface;
- and
- a coating at least formed on the second surface at a coating area thereof, wherein the coating is thermo-conductive and electro-insulating and is adapted to conduct heat from the at least one laminate through the second surface to the bezel.
