The method thus has the advantage of connecting components of different shape and or presented at different stages of finishing or coating (already coated, partially or not at all).
- FIG. 1 and 2 show a method of manufacturing an electronic box according to the invention
- FIGS. 3a and 3b show a variant provided by the invention for applying a first insulating layer on an island.
- Figures 1 and 2 show a system and a manufacturing method according to the invention.
- a first step S1 - of a method according to the invention - consists of depositing a chip 1 (from the slab) on an adhesive support 2 - such as an adhesive tape.
- the carrier 2 is preferably pulled to convey the chip - as indicated by the arrow D.
- the chip 1 is deposited on the adhesive support 2, the active face of the chip pointing downwards.
- said active face is directly in contact with the adhesive support 2.
- Figure 1 describes a chip 1 having two contact pads 1 a visible and present on said active face.
- the adhesive of the support 2 makes it possible to maintain it during the first stages of the manufacturing process.
- the adhesive hes 2 support is an adhesive strip whose width is 35 or 70 millimeters in order to be compatible with many equipment used, according to the state of the art, in the industry. Smartcard.
- the invention provides the manufacture of housings or modules respectively comprising one or more chips per housing or module. Such a device may even include an electronic component such as a capacitor for example, or a resonator. To simplify the presentation of the invention, we will first describe a first embodiment in connection with Figures 1 and 2, for which a housing has only one chip 1. Other examples of applications will be described later.
- a chip 1, deposited in step S1 moves with the aid of the adhesive support 2 to reach the vicinity of means 20 provided for molding a resin 3 around said chip 1.
- the second step S2 of the method can thus consist of a molding-transfer of a resin 3 applied around and on the non-active face of the chip.
- This resin 3, hardening, provides protection to the chip. It can also constitute the support or even directly the body of an electronic object such as, for example, a mini-UICC card. In the latter case, the thickness of the resin 3 is sized to meet the dimensional criteria of said object.
- the invention provides a variant for which S2 is applied to a resin 3, not only on a chip but also on a plurality of chips. We thus obtain a set "resin 3 plus chips 1" constituting what we will call an "island". We will see later that it is possible, at the end of the manufacturing process - by a division operation of said island - to find, not a single box, but a set of boxes from the same island.
- the shape of the island can be adapted to the chosen configuration.
- the molding applied to the non-active face of the chip while it is positioned on the support 2 is particularly advantageous: it does not weaken said chip.
- this molding technique allows to have islands whose active faces of the chips are flush and at the same level as the surface upper resin 3 forming the island.
- Step S3 of a method according to the invention thus consists in returning an island conveyed by the adhesive support 2 so that said island exposes the active faces of the chips.
- the invention provides different techniques for performing island rollover.
- a preferred embodiment is S3 to use a second towed adhesive medium 30 whose tack properties are 2.
- Such a support 30 - such as, for example, a band of a width comparable to the band 2 of FIG. 1 - is applied to the back of an island conveyed by the support 2.
- contact carrier 30 on the island causes the detachment of the latter support 2 and thus the flipping of the island since the latter is now véh iculé on the support 30, the active faces of the exposed chips.
- the invention provides that the reversal step S3 may consist of using a gripping tool to grip an island conveyed on the adhesive support 2, detach it from the latter, turn it over and deposit it, the active faces of the chips exposed on it.
- a support 30, such as an adhesive tape or a honeycomb support or any other type of support adapted to convey an island thus returned. Any other technique for returning an island could also be implemented according to the invention.
- the support 2 may be in the form of a consumable type band: it serves only a single pass.
- the invention provides that such a strip can be unwound at the beginning of the process and rewound at the end of step S3 so that the band can be reused a second time.
- a continuous band could also be exploited provided that the adhesive properties thereof remain sufficient to provide the functions of maintenance and conveying.
- FIG. 2 illustrates the subsequent steps of steps S1, S2 and S3.
- an island 10 is conveyed on a support 30 in a direction D.
- step S4 such an island is in the vicinity of means 41 for applying to the island 10 a layer of insulating material 4
- this layer does not completely cover the surface of the island 1 0 to leave at least one contact pad 1, a chip not covered by said insulating layer. It is thus possible, for example, to render inoperative a contact pad serving essentially to perform electrical tests upstream of the manufacturing method according to the invention.
- the means 41 may consist of a print head of an insulating ink.
- the means 41 are capable of producing a jet of an insulating material on said island.
- step S4 may be preceded by a step (not shown in FIG. 2) for depositing, on the active face of a chip 1 and / or on resin 3, a primer to facilitate the hangs up materials to drop.
- the following step S5 consists of depositing a conductive material 5 mainly to constitute a contact pad in connection with a contact pad 1a.
- a conductive material 5 mainly to constitute a contact pad in connection with a contact pad 1a.
- the means 51 are a print head - with numerical or piezoelectric control - capable of printing a conductive ink as a material 5.
- This embodiment is particularly advantageous because it is very easily adaptable to the topography of the plots of the chips. Other digital printing techniques could be used to deposit conductive inks such as, for example, aerosol ink deposition.
- the means 51 are associated with means 52 for adhering and facilitating the conductivity of the deposited conductive material.
- the means 52 can implement a pressure and / or heating action to cause the coalescence of nanoparticles contained in a conductive ink 5.
- Contact pads and / or electrical circuit elements may comprise or consist of nanoparticle particles.
- the means 52 may facilitate the removal of a jet-promoting solvent from an ink or conductive material by heating, for example, an island or drawing hot air thereon.
- the invention provides the use of any means adapted to fix the conductive material 5 and promote conductivity.
- FIG. 2 illustrates a subsequent and optional step S6 making it possible to deposit a second layer of insulating material 6.
- the island is positioned near means that are similar or identical to the means 41 and 42 described in connection with step S4 of FIG. process.
- This step makes it possible to isolate connection tracks made with conductive material 5, tracks that one does not wish to expose. It is thus possible to let appear contact pads, flush with the surface of the island, respectively connected to the pads 1a of the chip 1.
- insulating material arranged in a layer on the islands may be constituted or comprise insulating nanoparticles.
- FIG. 2 shows an embodiment for which the island is positioned near lasers 71. Under the action of a laser beam island 10 is cut precisely to the required dimensions.
- this step S7 makes it possible to individualize several sub-islands 10a, 10b, 10c from the island 10. We can from this how to factor the production of a set of modules or boxes to optimize the manufacturing time and split at the end of the process modules or modules.
- Other cutting techniques could be used: water jet, mechanical machining, diamond saw, etc.
- the invention preferably provides that inks can be used to make the insulating, conductive or bonding primer layers.
- the means 42, 52, 62 are adapted to the type of ink used: infrared lamp or diode, ultraviolet, pulsed hot air, microwave, oven, etc.
- the invention provides, alternatively, that printing techniques, such as screen printing, pad printing or any other printing technique can be used in addition to or in lieu of an inkjet or material.
- step S1 may consist in depositing, on the adhesive support 2, a set of chips and / or components necessary for producing a housing.
- the adhesive of the support 2 makes it possible to ensure the topography of the various electronic elements.
- Step S1 may also make it possible to deposit a plurality of component assemblies in order to factorize the manufacture of a plurality of packages.
- a step S2 makes it possible to mold in the same island all the electronic elements - or even a plurality of sets.
- the active faces of the chips and / or electronic components are all flush and at the same level as the upper surface of the resin 3.
- Step S5 of a method according to the invention makes it possible, besides materializing contact pads, to make all the connections between the electronic elements: more gold wires, less scrap associated with faulty wire connections, etc. .
- insulating and conductive layer deposition steps may be repeated to achieve a complex topography (or layout in English).
- the steps S5 and S6 can be repeated as much as necessary to achieve a crossing of conductive tracks for example.
- a step of type S7 makes it possible to individualize modules or housings thus manufactured. It can make it possible to refine the cut of said module or box according to strict standardized criteria.
- the invention provides an alternative embodiment as shown in connection with Figures 3a and 3b.
- FIG. 4 an adhesive support 2 comprising a thin layer of insulating material 2a. During the steps for depositing S1 a chip and for molding S2 the resin 3, the insulating material 2a is thus applied to the island.
- an island is detached from the support 2 but the layer 2a remains present as shown in Figure 3b. It is thus transferred from the adhesive support 2 to the island 10.
- the invention provides that part of said insulating layer 2a can be eliminated using various techniques (laser, thermal, ultraviolet, etc.).
- Fig ure 3b thus has an island 10 whose contact pads 1 has chips 1 are thus released.
- Such an island deposited on a support 30 can be treated subsequently according to the steps S5 to S7 as described previously with reference to FIG. 2.
- the invention provides for integrally keeping the film 2 applied to the islands and to pierce it at the pads so as to have a large protective layer above the chips or components.
- the invention also provides, in order to facilitate the step S3 of molding the resin 3, to use a mold whose walls coming into contact with the adhesive support 2 are treated (for example with teflon) in order to reduce the adhesion. of the latter on the support 2.
- the adhesive support 2 may be devoid of adhesive material on outer strips so that the mold does not come into contact with said adhesive material.
- the invention has been described and illustrated in the field of manufacturing modules or electronic boxes operated in the chip card industry.
- the invention can not be limited to this single application example but can also be applied to other fields and technologies.
- the invention generally relates to a method for manufacturing an electronic box (10a, 10b, 10c) comprising a chip (1) whose active face comprises at least one contact pad (1 a), said method being comprising the steps following:
- the support is not necessarily towed, it can be supplied in plate.
- the chips can be fixed by any means on the support: adhesive or mechanical or physical attachment means.
