As described above, in the conventional solder supply method for soldering electronic parts,
Solder was supplied by the above-described various methods to each portion of the individual electronic component that requires soldering. Therefore, there is a problem that it takes a considerable amount of time and labor to supply the solder. Further, in the method of connecting the electronic component and the case with the conductive adhesive, it is necessary to supply a relatively large amount of the conductive adhesive in order to hold the electronic component in the case. Therefore, a space for accommodating a relatively large amount of the conductive adhesive is required, which hinders downsizing of electronic components.

In this embodiment, the electronic component 7 constitutes the ceramic oscillator as described above, and the solder coating films 6a 'and 6b' have already been formed on the electrode portions which need to be soldered.
Is given. Therefore, the electronic component 7 shown in FIG.
After being inserted into the case, the printed circuit board, the terminal or the like, it can be immediately joined to the case, the printed circuit board or the terminal by soldering by the reflow soldering method. As described above, in the electronic component soldering method of this embodiment, the solder coating films 6a and 6b are formed at the stage of the mother electronic component unit 1. Therefore, conventionally, while solder was supplied in units of individual electronic components, a solder coating film can be formed in a portion where soldering of a plurality of electronic components is required by a single solder supply step, It can be seen that the efficiency of the electronic component soldering method can be dramatically improved.

In the soldering method of the above embodiment,
As shown in FIG. 2, the solder coating film was formed by dipping the mother electronic component unit 1 into the molten solder 5, but as shown in FIG. 5, a cream solder layer smoothed to a predetermined thickness by a squeegee. It is also possible to press the mother electronic component unit 1 against the stage 9 having 8 so that cream solder is attached and dried on the electrodes 3a and 3b to form a solder coating film. Further, in the above-described embodiment, as shown in FIG.
As is apparent from the above, the solder coating film is not formed on the side surface 7a of the obtained electronic component 7. Therefore, the soldering method of the present invention can be preferably used to apply the solder plating to the external electrodes of the chip-type electronic component which does not require soldering on the side surface.

According to the present invention, the solder coating film is formed by solder dipping or cream solder dipping at the stage of the mother electronic component unit. Therefore, the solder supply process can be performed more efficiently than the conventional method in which the solder is supplied to each part where soldering of individual electronic components is required, and the work process of the entire electronic component soldering method is simplified. In addition, it is possible to shorten the time required for the manufacturing process of the electronic component.

Since the thickness of the solder coating film formed by the solder dip is usually as thin as about 0.05 to 0.1 mm, the solder coating film is formed on the mother electronic component unit as described above. Even if it is installed, it does not hinder cutting with a dicer or the like. In addition, as described above, the solder is not supplied to the cut surface in the individual electronic components obtained by cutting the mother electronic component unit,
Handling of electronic components during soldering becomes easy, and work such as transfer can be performed more reliably. Therefore, according to the present invention, it is possible to improve the handleability in the production of electronic components without causing any trouble, and it is possible to significantly enhance the productivity of electronic components.
