Definitions

  • This invention relates to electrical power supplies for circuit boards.
  • a further problem associated with batteries is the need to connect by clips or wires soldered to the battery the circuit it is to power. This adds undesirably to the component count and the number of operations to be performed to make the circuit.
  • a circuit board with an electrical power supply comprising a cell formed integrally in the circuit board.
  • the cell By forming the cell integrally in the circuit board, it is possible to eliminate the requirement for a separate casing, since in effect the circuit board performs that function. This allows a reduction in size and weight of the power supply, and allows it to be readily accommodated in the available space provided by the board.
  • the cell may be rechargeable or nonrechargeable.
  • the electrically conductive surface will be that provided to be etched to a required circuit pattern and to which electronic components are soldered to form a circuit. Commonly these surfaces are made of copper because of its good electrical conductivity.
  • the circuit board may be rigid or, where it is to conform to another shape, such as an inside surface of a case, it may be made flexible. Where it is flexible, the cell is also preferably flexible.
  • the cell may be formed in a cavity, depression, aperture or blind hole made in the surface of the circuit board by, for example, drilling or grinding. Where a hole is made through one of the surfaces, a vapour or gas proof layer may be provided to seal the hole against the ingress of contaminants and/or the leakage of vapour of gas as the cell operates.
  • the vapour proof layer is electrically conductive to provide an electrical connection to the cell.
  • the vapour proof layer is preferably sealed at its junction with an adjacent electrically conductive layer of the circuit board by an electrically conductive sealant serving to provide a vapour proof seal and to electrically connect the layers.
  • the cell is formed within the board before addition of the electrically conductive surface or surfaces.
  • the electrically conductive surfaces will then provide vapour proof layers eliminating the requirement for an additional layer and sealant.
  • Figure 1 shows a plan view of an electrical power cell and a circuit board in accordance with a first embodiment of the invention
  • Figure 2 is a section along line II-II of Figure 1; and Figure 3 is a section through an electrical power cell and circuit board in accordance with a second embodiment of the invention.
  • a printed circuit board 1 has an electrically insulating resin core 2 clad by upper and lower electrically conductive copper layers 3 and 4 respectively.
  • the copper layers 3 and 4 are selectively etched, in a manner well known, to provide a network or circuit pattern of electrically conductive tracks (not shown).
  • Circuit components 5 are soldered to these tracks to form a circuit.
  • the components 5 may include microprocessors, resistors or other electronic/electrical components to suit the electrical application for which it is designed.
  • the electrical power cell 7 is a lithium solid state battery and comprises an anode of lithium metal foil 8 placed in the hole in good electrical face-to-face contact with the lower copper layer 4.
  • a layer of polymer electrolyte 9 is provided over the upper surface of the lithium foil 8.
  • the aluminium foil backing 11 provides a vapour proof covering as well as an electrical pick up from the cell 7.
  • a fillet 12 of conductive epoxy sealant completes the vapour proofing of the cell 7 and additionally electrically connects the cell 7 to the upper copper layer 3.
  • connection between the cell 7 and the circuit components 5 is completed by through hole plating (not shown) to the lower copper layer 4.
  • a second embodiment of the invention is shown in Figure 3 in which like parts are given the same reference numbers as for the first embodiment.
  • a cell 7 is in this case formed in an aperture in a core 2 of a circuit board 1 prior to a cladding process in which copper layers 3 and 4 are glued to the core 2.
  • the layers 3 and 4 encapsulate the cell 7 preventing ingress of contaminants.
  • the copper layers 3 and 4 are then etched in a manner well known to provide a network of conductive tracks to which electronic components 5 are soldered to complete the board 1.
  • a number of cells may be provided at different locations in the circuit board and electrically linked in series or parallel to give the required voltage and capacity.
  • vapour proof layer and sealant may be dispensed with, their function being performed by the conductive layers alone.

Abstract

L'invention concerne une carte à circuits imprimés (1) incorporant une cellule électrique (7) faisant partie de la carte. L'incorporation de la cellule dans la carte (1) évite la nécessité de prévoir un boîtier pour la cellule (7) et des câbles de liaison, ce qui réduit le poids de l'ensemble et le nombre de composants par rapport aux configurations de l'antériorité.
