FIELD: radio engineering, in particular, for embedding integral circuits into cards. SUBSTANCE: invention discloses device design which provides targeted control of heat flow which enters integral circuit assembly from outside due to either heat insulation layer introduced between flexible carrying ribbon of integral circuit assembly and integral circuit glued over it, or recesses in surface or layer of metal contacts. Heat flow from hollow upper die which is located in external region of metal contacts is interrupted in direction towards integral circuit which is mounted in center. EFFECT: prevention peelings between cover body and integral circuit which is embedded by means of hot gluing. 4 cl, 4 dwg
