A method is provided for electrically connecting a first electronic component which is not resistant to a reflowing temperature and a second electronic component which is resistant to the reflowing temperature to a substrate. The method includes the steps of applying cream solder to a first predetermined portion of the substrate so that the first electronic component is connected therewith and to a second predetermined portion of the substrate so that the second electronic component is connected therewith, mounting the second electronic component on the substrate, heating the second electronic component mounted on the substrate by reflowing so as to solder the second electronic component onto the substrate, forming a pre-soldered portion made of cream solder on the first predetermined portion of the substrate, applying flux to one of the first electronic component and the pre-soldered portion, mounting the first electronic component on the first predetermined portion of the substrate, melting the cream solder of the pre-soldered portion by heating the substrate locally, and soldering the first electronic component onto the substrate. Another method for electrically connecting an unwashable electronic component and a washable electronic component to a substrate includes similar steps to those of the method above.

A film material for the manufacture of a film carrier has a lead pattern including an outer lead portion formed independent of the electrode arrangement of a semiconductor chip to be mounted on the film carrier, and an inner lead formation portion a part of which is selectively removable in accordance with the electrode arrangement of the semiconductor chip to be mounted thereon, the inner lead formation portion being contiguous and connected to respective leads of the outer lead portion. A method for manufacturing the film carrier includes the steps of forming a conductive layer of material on a film; forming the lead pattern by etching part of the layer formed on the film into an outer lead portion having a pattern independent of the electrode arrangement of each semiconductor chip to be mounted thereon, and by leaving another part of the layer as it is to form an inner lead formation portion having a pattern which is changeable according to the electrode arrangement of the semiconductor chip to be mounted thereon; and selectively removing part of the inner lead formation portion by laser processing in accordance with the electrode arrangement of the semiconductor chip to be mounted thereon.

A package is used for keeping an electric circuit board with no electronic components provided thereon in an air-tight cavity thereof and for preventing from oxidation during the transportation to the process wherein the electronic components are mounted on the electric circuit board. The cavity is composed of the lower and upper sheet of gas-impermeable materials, which are bonded at the bonded area by the fusion bonding, adhesive agent or viscous agent. The cavity is kept in non-oxidizing atmosphere by filling inert gas or evacuating air therefrom. The lower and upper sheets are composed of single layer or multi-layers, which may be made of flexible material or rigid material. An electric circuit board accommodated in the cavity of the package is taken out by the device comprising a separation roller pair. The device weakens the bonding strength to enable easy pulling of the lower and upper sheets to unpackage the circuit board.
