Definitions
- the present invention is in the field of electronic modules and methods of manufacturing said modules comprising a plurality of layers formed by superimposed sheets and at least one electronic component.
- the invention relates to modules manufactured by pressing and thermoforming of different successive layers, these modules comprising at least one electronic component defined here as an element such as a coil connected to a chip most often called a transponder.
- modules such as smart cards, electronic labels or electronic circuits are produced by assembling several sheets to form superimposed layers, namely a support called substrate, a conductive layer and protective sheets covering the faces of the module.
- the electronic component fixed on the substrate is connected to the tracks of the conductive layer. All these sheets are assembled either by heat bonding using a press, or by lamination.
- modules are made by coating an electronic circuit with a binder. After hardening of the binder, the faces of the module are, in general, covered with protective sheets serving as decoration.
- the object of the present invention is to provide a method for manufacturing electronic modules with high profitability. More particularly, this process is distinguished by stages requiring simplified tools allowing rapid production of a very large quantity of modules.
- the present invention also aims to obtain a reliable electronic module while having a very low final cost.
- This object is achieved by a method of manufacturing an electronic module comprising at least one electronic component transported on a tray used for handling electronic components and comprising cells, and a second insulating sheet characterized by the following steps:
- the electronic components are delivered by the supplier in a package, the basic element of which is a tray formed by a thermally formed insulating sheet.
- This tray used for transporting and handling the components, has cells regularly distributed over its surface.
- a cell contains a component.
- the use of such a component packaging element considerably reduces the number of operations in the module manufacturing process. Indeed, the preliminary stages of preparation of the first sheet, the manipulations and the positioning of the transponders which can prove to be delicate are no longer necessary.
- the first step of the process will therefore consist of superimposing a second insulating sheet on the first so as to close all the cells containing a component. Then, this assembly is hot pressed by means of a pressing plate applied to the second insulating sheet to form a plate incorporating a large number of components. This plate will be cut in order to obtain isolated modules comprising at least one component.
- a filling material consisting for example of a resin
- the assembly can be either hot pressed or, according to another variant, the second insulating sheet is applied by gluing alone without pressing.
- the second sheet may include a layer of self-adhesive material on the face intended to be applied to the first insulating sheet.
- the final cutting of the modules is carried out by stamping, for example, according to a contour defined by that of a cell of the first insulating sheet where the electronic component is housed.
- the contour of the module includes several cells.
- the present invention also relates to an electronic module comprising an assembly of a first insulating sheet, at least one electronic component and a second insulating sheet characterized in that the first insulating sheet comes from a material handling tray.
- electronic components comprising cells each containing at least one electronic component.
- the module may include a layer of filler material between the first and second insulating sheets. This material, generally in the form of resin, coats the electronic component (s).
- FIG. 1 shows a general view of a tray comprising cells each containing a transponder.
- FIG. 2 shows a sectional view of the tray containing the transponder
- FIG. 3 shows a sectional view of the tray containing the transponder with a second sheet closing the cells
- FIG. 4 shows a variant of Figure 3 where the second sheet is thermoformed.
- FIG. 5 shows a variant with two superimposed trays
- FIG. 8 shows a sectional view of the assembly after pressing with several superimposed sheets.
- FIG. 1 illustrates an overall view of the first insulating sheet (1) in the form of a tray constituting the basic element for the packaging and handling of electronic components provided with cells (2) each containing a transponder (3).
- the cells (2) are, in general, adapted to the dimensions and the shape of their content.
- This tray is introduced as is with the components (3) in the module manufacturing process. The first two stages of the process which would consist, on the one hand, of preparing a first sheet and then on the other hand, of depositing the components in a precise manner on this sheet are thus eliminated.
- Figure 2 shows a section along the axis A-A of the first insulating sheet (1) whose cells (2) contain the transponder (3).
- Figure 3 shows the first step of the shortened process which consists of superimposing a second sheet (4) on the first insulating sheet (1) so as to close all the cells (2) containing a transponder (3).
- This second sheet may include a layer of self-adhesive material on the internal face applied to the first sheet (1).
- the cells can be filled with a resin before the assembly of the second insulating sheet (4) in order to coat the electronic component (3).
- FIG. 4 illustrates a variant where the second sheet (5) has cells obtained by thermoforming. The dimensions of these cells are chosen so that these cells can fit into the cells (2) of the packaging element (1) when the second sheet (5) is superimposed on the first (1).
- This second sheet (5) can also be a second tray for handling electronic components whose cells are empty.
- FIG. 5 illustrates another variant where two plates (1, l ') containing an electronic component (3, 3') are superimposed.
- the second tray is covered by a cell sheet (5) as in FIG. 4.
- This example shows that several trays containing components can be stacked so that the cells interlock with one another.
- the last tray is covered by a sheet with cells or not (see Figure 3).
- this type of configuration is advantageously used for the manufacture of modules comprising several transponders each working at a different frequency.
- Figure 6 shows an exemplary embodiment where a sheet (6) is added between the packaging element (1) and the second sheet (4).
- An additional sheet is added between the packaging element (1) and the second sheet (4).
- (7) can also be assembled on the opposite face of the assembly.
- the intermediate sheets or those assembled last can include a decoration or a marking allowing the identification of the modules after their cutting in the pressed plate.
- one or other of the sheets constituting the external faces of the final module can comprise a layer of self-adhesive material serving to adhere the module to the surface of any support.
- such a module constitutes, for example, an electronic label used to identify an object.
- the sheets used (4, 5, 6) may include transparent zones playing the role of windows making all or part of the transponder or of the component visible.
- some intermediate sheets may have openings which are generally covered by the transparent areas of outer sheets or by fully transparent sheets. These openings are made in the area where the component is located so as to allow it to appear entirely, partially or in parts distributed over the surface of the module. This property makes it possible to distinguish an authentic transponder module from an imitation comprising no component.
- Figure 7 illustrates the assembly after hot pressing of the base sheet (1), transponders (3) and the cover sheet (4).
- the product thus obtained is a thin plate formed by the juxtaposition of the two sheets (1, 4) between which the transponders (3) are embedded.
- the electronic modules are then cut from the plate according to a predefined contour in the zones (D) separating the cells.
- the sheets conform to the shape of the components after pressing because of their thinness.
- This type of embodiment is suitable for example for electronic labels intended to be affixed to objects.
- FIG. 8 illustrates an assembly after hot pressing of several sheets superimposed on each face (1, 4, 5, 6, 7), between which there are transponders (3).
- the product thus obtained is a thick, rigid plate with substantially flat faces. This achievement applies for example to the manufacture of badges, keys or electronic cards.
- All the insulating sheets used in the module manufacturing process may include orifices (holes, slots) and / or relief structures (grooves, channels, embossing) used to evacuate the air trapped in the cells during pressing operations. Indeed, the air escapes through the orifices and / or laterally through the edges of the plate thanks to the relief structures, which prevents the formation of undesirable bubbles on the surface of the modules.
- the orifices or relief structures of the insulating sheets also serve to evacuate the excess resin from the cells during pressing.
