Definitions
- the invention is based on a circuit board with a heatsink. It is known to attach a metal element serving as a heat sink to a printed circuit board. The metal element serves to absorb the heat generated in the printed circuit boards and to release it to the environment.
- the invention has for its object to provide a way to provide a defined dielectric strength in the area of the heatsink.
- the invention proposes a printed circuit board with the features of claim 1 and a method with the features mentioned in claim 5. Further developments of the invention are the subject of the dependent claims, the wording of which, like the wording of the summary, is made the content of the description by reference.
- the task of the frame delimiting the adhesive layer between the circuit board and the metal element is to ensure that the adhesive layer does not exceed a precisely defined area at the edges. This creates a constant thickness of the dielectric.
- the frame is glued to the circuit board through the adhesive layer which rises on the inside between the frame and the metal element.
- the adhesive layer is formed by an adhesive film.
- the bond is produced by pressing.
- the method proposed by the invention provides for at least provisionally fixing or positioning the frame on the printed circuit board and then inserting the metal element into the frame with the interposition of an adhesive layer and pressing it against the printed circuit board. It can be provided that the adhesive layer is dimensioned such that the adhesive rises slightly at the edge on the inside of the frame and in this way also glues the frame to the circuit board.
- the invention proposes to use an adhesive film as the adhesive.
- Figure 1 is a plan view of a corner of a circuit board with a heatsink in a frame.
- FIG. 2 shows a side view of the arrangement according to FIG. 1
- FIG. 3 shows schematically the individual parts of an arrangement according to the invention
- Fig. 4 shows a section through an embodiment modified compared to Figs. 1 and 2.
- a frame 2 is attached to the printed circuit board 1, which otherwise has a normal structure, within which a metallic element 3 is glued to the printed circuit board.
- the metallic element 3 is surrounded by the frame 2 at a close distance.
- the adhesive used is an adhesive with good thermal conductivity.
- the metallic element 3 is fastened to the printed circuit board 1 in such a way that the frame 2 is initially positioned at the desired location, for example with the aid of pins. Then an adhesive film in a size corresponding to the corresponding area of the metallic element 3 is placed in the frame 3 on the printed circuit board 1 and then the metallic element 3 is inserted into the frame. The metallic element 3 is then pressed against the printed circuit board 1.
- FIG. 3 now shows in perspective how the heatsink 3 is attached to a circuit board 1.
- a copper foil with or without bores, for example, is present on the printed circuit board 1 and is to be cooled.
- the frame 2 is placed around this point, and, as mentioned at the beginning, a fixation can also be carried out.
- 2 adhesive in the form of an adhesive film 5 is inserted into the interior 4 of the frame.
- the metallic element 3 forming the heatsink is also inserted into the opening 4 of the frame and glued to the circuit board 1 with the aid of the adhesive film 5. This creates an arrangement as shown in Figures 1 and 2.
- the gap between the frame 2 and the adhesive is selected.
- FIG. 4 shows a possibility where the heatsink 3 is not arranged within the frame 2 but lies on the side of the frame 2 facing away from the printed circuit board 1 .
- the interior 4 of the frame 2 is completely filled with adhesive 5 in this case.
- a defined dielectric strength can also be achieved in this way.
- the heatsink 3 can also protrude beyond the frame 2 on one or more sides. In this way, the volume of the heatsink and its surface serving to radiate the heat can be increased with a likewise defined dielectric strength.
- the heatsink 3 can of course also have other shapes.
