Method for creating a multifunctional module and device including same
View Patent ↗The invention relates to a method for creating a multi-component device, including the following steps, creating a module having a multilayer structure comprising electrical/electronic components arranged on at least one substrate in stacked layers, the components each having a main surface exposed to the outside, wherein the components are arranged such that the respective main surfaces thereof are oriented in mutually opposite directions. The invention also relates to the corresponding device.
1. A method for creating a multi-component device, including or forming a chip card module, with said method including the following steps:
making a chip card module having a multilayer structure comprising electrical/electronic components connected together and arranged on at least one substrate in stacked layers, the components being mounted on respective portions of the at least one substrate which face in mutually opposite directions, and
inserting said chip card module, including said components and said at least one substrate, into a recess of a body of the device, said device body having an opening on a main face, with the insertion being performed through said opening,
wherein the components include a microcontroller in the form of an integrated circuit chip which drives at least one other of the components, and wherein the components are arranged so that a main surface of at least one of said components is exposed to the outside at the opening for a direct visual or tactile interaction with a user, and said at least one of said components is mounted to a surface of the at least one substrate, wherein said surface faces the opening.
2. A method according to claim 1 , wherein the components are positioned on two opposite faces of the substrate.
3. A method according to claim 1 , wherein the substrate is a double-folded substrate, and the components are positioned on the same face of the double-folded substrate.
4. A method according to claim 1 , wherein the components are positioned each on different substrates assembled back-to-back afterwards.
5. A method according to claim 1 , wherein the recess opens onto each opposite main face of the body of the device.
6. A multi-component device including or forming a chip card module with a multilayer structure comprising at least two electrical/electronic components connected together and arranged on at least one substrate in stacked layers, wherein the components include a microcontroller in the form of an integrated circuit chip which drives at least one other of the components, and wherein the components are mounted on respective portions of the at least one substrate which face in mutually opposite directions, said chip card module, including said components and said at least one substrate, being inserted into a recess of a body of the device, said device body having an opening on a main face, with the insertion being performed through said opening, wherein the components are arranged so that a main surface of at least one of said components is exposed to the outside at the opening for a direct visual or tactile interaction with a user, and said at least one of said components is mounted to a surface of the at least one substrate, wherein said surface faces the opening.
7. A device according to claim 6 , wherein the components are positioned on two opposite faces of the substrate.
8. A device according to claim 6 , wherein the substrate is a double-folded substrate, and the components are positioned on the same face of the double-folded substrate.
9. A device according to claim 6 , wherein the components are positioned each on different substrates assembled back-to-back.
10. A device according to claim 6 , wherein the recess has an opening on each opposite main face of the body of the device.
