US 7,682,871 B2 · Method for forming a joint

Abstract

A method for forming a joint. A module is introduced including a paper or plastic substrate, an integrated circuit on a chip mounted on the substrate and in electrical contact with contact areas of the module being located on the surface of the substrate. A web is introduced including one circuitry pattern after another provided with contact areas of the circuitry pattern. Settable isotropically conductive adhesive is dispensed on the contact areas of the circuitry pattern. The contact areas of the module are attached to the contact areas of the circuitry pattern by the isotropically conductive adhesive. The isotropically conductive adhesive is cured at the ambient atmospheric pressure. Settable nonconductive adhesive is dispensed at the side of the module in such a manner that the adhesive is sucked underneath the module by capillary forces. The nonconductive adhesive is cured at the ambient atmospheric pressure.

Dependent claims

A method for forming a joint, comprising:

providing a module comprising a paper or plastic substrate, the module further comprising first contact areas located on a surface of the substrate, and the module further comprising an integrated circuit on a chip mounted on the substrate and being in electrical contact with the first contact areas;
providing a web comprising a plurality of adjacent circuitry patterns comprising second contact areas;
dispensing a settable isotropically conductive adhesive on the second contact areas;
attaching the first contact areas to the second contact areas;
dispensing a settable nonconductive adhesive at a side of the module such that the settable nonconductive adhesive is sucked underneath the module by capillary forces;
curing the settable nonconductive adhesive at an ambient atmospheric pressure;
reeling the web up after curing the settable nonconductive adhesive;
and
storing the reeled up web for a time and temperature effective to cure the isotropically conductive adhesive at the ambient atmospheric pressure after curing the settable nonconductive adhesive.
