Abstract
The process for mounting an integrated circuit (11) on a support (10) comprising a structure (13) of conductors (14) comprises connecting the conductors to respective terminals (12) of the integrated circuit without interposing a part of the support for insulating the conductors of the integrated circuit as in the standard TAB technology. The connection can be made directly by thermocompression or ultrasound, or indirectly through ball bonds. It is only after the connection that the insulation between the conductors and the integrated circuit is applied. The insulating substrate of the TAB support (10) can be attached to the conductors outside the integrated circuit, before or after the connection of the conductors.
Claims5
A process for fitting an integrated circuit (11) with a structure (13) of conductors (14) provided for connecting input-output terminals (12) of the integrated circuit, each said conductors (14) including a respective end portion and a corresponding body portion, said process comprising the steps of:
- connecting a free end portion of each conductor to a respective terminal of the integrated circuit without interposing an insulator between a corresponding body portion of said each conductor and the integrated circuit during said connecting step;
- separating the body portion of said each conductor from the integrated circuit by applying a force (F) to the face of the integrated circuit, the force (F) being perpendicular to the face, without interfering with the connection of the free end portion of said conductor;
- and
- maintaining a separation of said body portion from said integrated circuit by adding an insulator between said body portion of said each conductor and the face of the integrated circuit.
The process according to aim 2, wherein the separation is maintained by introducing at least one electrically insulating spacer (22) between said conductors (14) an d said integrated circuit (11).
The process according to claim 4, further including linking said at least one insulating spacer (22) to an insulating frame (24) attached to the conductors at an attachment point located outside the integrated circuit area.
