Electronic apparatus mounting arrangement

摘要

In a thin electronic calculator having a circuit board unit in which an IC pellet (10) is directly mounted on a film board (71) by means of metal foil lead (74) fixed to one surface of the film board, the circuit board unit is fixed to a wiring board by an anisotropically electrical conductive adhesive (12), and the electronic component assembly constituted by the circuit board unit and the wiring board is received in upper and lower covers, and is adhered by adhesive islands deposited on the covers.
