Definitions
- the present invention relates to an electronic component mounting method in which terminals formed on a side surface of an electronic component and electrodes formed on a substrate on which the electronic component is mounted are mounted by solder bonding.
- soldering for example, an electrical connection terminal provided on the side surface of the ceramic package to an electrode provided on the substrate.
- connection electrode is electrically connected to the circuit electrode of the substrate.
- solder joint the location where the solder is connected, that is, the solder joint, is formed on the terminal on the side surface of the electronic component and the electrode on the board, so that the electrical and mechanical reliability of the solder joint is sufficiently secured.
- solder joints are reinforced with a resin adhesive that is difficult to handle (for example, Japanese Patent Application Laid-Open No. 2004-146433).
- FIG. 4A shows a part of a conventional electronic component.
- solder paste mixed with Sn-Bi-based lead-free solder particles in a conventional thermosetting flux that does not contain plasticizer the terminals 14 on the side of the electronic component 10 are connected to the electrodes 12 on the substrate 11.
- the solder joint structure when soldered is shown.
- solder joint structure shown here it is difficult to form a solder fillet of a desired shape due to the characteristics of Sn—B lead-free solder, and sufficient joint strength is often not secured. That is, most of the solder supplied for joining the electrode 12 and the terminal 14 is In reflow, the solder balls 18d become discrete along with the flux components. For this reason, a sufficient amount of solder can be secured in the solder joint 18a, and the solder joint tends to be irregularly shaped.
- FIG. 4B shows a conventional solder joint structure, in particular, a solder joint structure using a solder paste in which a plasticizer is mixed in a thermosetting flux.
- this indicates a malfunction that occurs when the relative relationship between the softening start temperature of the plasticizer and the liquidus temperature of the solder is inappropriate.
- a soldered part once soldered such as a first-side part on a double-sided mounting board, is used for soldering of other parts. If the undesired overheating treatment is performed, it will be heated again during reflow.
- the solidified solder joint 18a is again heated above the liquidus temperature and remelted and fluidized.
- the resin reinforcing portion 18b formed so as to cover the solder joint portion 18a is similarly heated.
- the softening start temperature of the plasticizer is higher than the liquidus temperature of the solder, the plasticizer remains in a solid state at the time of solder melting, so that the resin reinforcing portion 18b is not softened and the soldering portion 18b is not softened.
- the joint 18a prevents free expansion of the molten solder.
- the melted solder also causes the gap between the grease reinforcing part 18b and the terminal 14 to flow outside, protruding (see arrow a), and generating a void (see arrow b) in the grease reinforcing part due to the outflow of solder.
- the solder joint 18a may have an abnormal shape.
- FIG. 4B the same reference numerals are used for the same portions as in FIG. 4A.
- the grease adhesive is supplied to the substrate or the electronic component. Therefore, a special process such as resin coating with a dispenser is required. In addition, the manufacturing process becomes complicated, and as the electronic components to be mounted become smaller and smaller, it becomes difficult to secure a space for supplying the resin adhesive.
- An object of the present invention is to provide a mounting method of an electronic component that can improve the reliability of electrical and mechanical joining of the joining terminals in the electronic component.
- an electronic component having a terminal on a side surface is used as an electrode of a substrate.
- This is a mounting method of electronic components to be mounted by solder bonding. It includes a solder paste printing process in which solder paste, in which solder particles are mixed into thermosetting flux, is applied to the electrodes provided on the substrate. Then, the terminals provided on the electronic component are brought into contact with the solder paste applied to the electrodes provided on the substrate.
- the electronic component mounting step of mounting the electronic component on the substrate in a state where a gap is provided between a part of the electronic component and the substrate facing the electronic component is provided.
- a heating process is provided in which the solder of the solder paste is melted by heating the substrate, the thermosetting flux of the solder paste is fluidized and infiltrated into the gap, and then thermally cured.
- a solder paste in which solder particles are mixed in a thermosetting flux is applied to an electrode provided on a substrate, and a terminal of an electronic component is brought into contact with the applied solder paste.
- the electronic component is mounted on the substrate and reflowed with a gap provided between a part of the bracketed electronic component and the substrate facing the bracket. Thereby, the solder of the solder paste is melted.
- the thermosetting flux of solder paste is fluidized and penetrates into the gaps, and then the electronic components are reinforced with thermally cured grease to improve the electrical and mechanical reliability of the terminal joint.

- the terminal 4 is soldered to an electrode formed on the substrate, so that the body of the package substrate 2 is fixed to the substrate and the terminal 4 is electrically connected to the electrode provided on the substrate.
- the solder paste 7 used for mounting the electronic component 1 on the substrate 5 by solder bonding contains a metal component containing solder particles, a thermosetting resin and a solid resin as a plasticizer, and has an active action to remove the solder oxide film. It is a composition in which a thermosetting flux is mixed. Solid resin is a so-called thermoplastic resin that is solid at room temperature and has the property of changing to a liquid state upon heating. As the solder, so-called lead-free solder that does not contain lead components is used, and two types of solder are used depending on the characteristics of the board and electronic component to be mounted.

- Sn (tin) -Bi (bismuth) solder (liquidus temperature 139 ° C) is used for electronic components where it is desired to set the heat treatment temperature as low as possible.
- Sn-Bi solder can improve the bonding strength of the solder by adjusting Ag (silver) to a blending ratio of lwt% to 3wt%. These solders are contained in the solder paste at a compounding ratio in the range of 70 wt% to 92 wt%.

Show the state. As shown in FIG. 3, the electrode 6 and the terminal 4 are connected by a fillet-shaped molten solder. Further, the thermosetting resin contained in the solder paste 7 softens and softens as the temperature rises, and is placed in a fluid state together with the liquid plasticizer. The oil component placed in the fluid state acts so as to cover the solder joint portion 8a and the electrode 6 also with the upper surface side force. A part of the resin component penetrates into the gap S between the electronic component 1 and the substrate 5 by capillary action. Through these processes, thermosetting of the thermosetting resin in the solder paste 7 proceeds simultaneously.
- the substrate 5 is taken out of the reflow apparatus and returned to room temperature.
- the plasticizer and molten solder contained in the solder base 7 are solidified.
- the melted solder is solidified to form a fillet-shaped solder joint 8a in which the electrode 6 and the terminal 4 are connected.
- the resin component covering the solder joint 8a and the electrode 6 also covers the upper surface side force, so that the resin reinforcement 8b that reinforces the solder joint 8a is formed.
- the resin component that has entered the gap S between the electronic component 1 and the substrate 5 is solidified, whereby a resin adhesive portion 8c that fixes the electronic component 1 to the electrode 6 is formed.
- a solder joint structure 8 formed by soldering the terminals 4 of the electronic component 1 and the electrodes 6 of the substrate 5 using the solder paste 7 is formed.
