Abstract
Abstract A method for positioning an electronic component and its contacts on a card is disclosed. The electronic component is first of all placed in the cavity of the card, then the electrical contacts are placed on the card and electrically connected to the output terminals by a so-called tape automatic bonding process using a film on which the electrical contacts are deposited.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
153 words
A method to fix an electronic component and its external contacts on a support, said support comprising a cavity to house said component, said method comprising the following operations: (a) positioning the electronic component (22) in the cavity (21), so that output terminals (23-26) of the component are accessible through the opening of the cavity; (b) positioning the external electrical contacts (27-30) on a supporting film (31), according to a pattern appropriate to the geometry of the output terminals of the electronic component; (c) positioning the electrical contacts on the support (20) by means of the supporting film (31); (d) simultaneously electrically connecting said electrical contacts (27-30) to the output terminals (23-26) of the electronic component (22); wherein prior to the first positioning step (a), the electronic component is coated with resin which allows the output terminals (23-26) to extend through said protective resin coating whereby the surface of the component is protected.
Claim 2
Independent Claim
153 words
A method to fix an electronic component and its external contacts on a support, said support comprising a cavity to house said component, said method comprising the following operations: (a) positioning the electronic component (22) in the cavity (21), so that output terminals (23-26) of the component are accessible through the opening of the cavity; (b) positioning the external electrical contacts (27-30) on a supporting film (31), according to a pattern appropriate to the geometry of the output terminals of the electronic component; (c) positioning the electrical contacts on the support (20) by means of the supporting film (31); (d) simultaneously electrically connecting said electrical contacts (27-30) to the output terminals (23-26) of the electronic component (22); wherein prior to the first positioning step (a), the electronic component is coated with resin which allows the output terminals (23-26) to extend through said protective resin coating whereby the surface of the component is protected.
Claim 3
Dependent Claim
26 words
A method according to claim 1, wherein said resin is a heat settable resin and is hardened by heating to a temperature of about 300° C.
