DELAYED ADHESIVE ACTIVATION
Apparatuses, methods, and systems are disclosed for an adhesive including an activated portion and an unactivated portion. The adhesive is interposed between and binds the first substrate to a second substrate. The unactivated portion includes moisture, and the activated portion is activated to adhere in response to the removal of moisture. Similarly, the unactivated portion of the adhesive may be activated in response to the removal of moisture, removal of air, applying radiation, heating, and/or catalyzing a functional group.

METHOD FOR MANUFACTURING SMART CARD, SMART CARD, AND CONDUCTIVE PARTICLE-CONTAINING HOT-MELT ADHESIVE SHEET
A method for manufacturing a smart card capable of achieving excellent connection reliability and bending resistance, a smart card, and a conductive particle-containing hot-melt adhesive sheet. A conductive particle-containing hot-melt adhesive sheet containing solder particles of a non-eutectic alloy in a binder containing a crystalline polyamide having a carboxyl group is interposed between a card member and an IC chip and subjected to thermocompression bonding. The crystalline polyamide having a carboxyl group improves the solder wettability of the non-eutectic alloy, thereby achieving excellent connection reliability. This effect is considered to be a flux effect due to the carboxyl group present in the crystalline polyamide, and as a result, it is possible to prevent the decrease in the elastic modulus of the adhesive layer which would be caused by the addition of a flux compound and to achieve excellent bending resistance.
