Definitions
- the present invention relates to a flux containing a surfactant.
- the flux used for soldering removes the metal oxides present on the metal surface of the solder alloy and the object to be soldered, and allows the movement of metal elements at the boundary between them. Has the effect of For this reason, by performing soldering using a flux, an intermetallic compound can be formed between the solder alloy and the metal surface of the object to be joined, and a strong joint can be obtained.
- the electrode pitch which is the soldering part of the electronic components, has been narrowed.
- a solder bump is formed by applying flux to the electrodes and heating a core ball or solder ball coated with a metal core such as Cu with solder, if the electrode pitch is narrowed, a solder bridge is formed between the pitches. It tends to occur. The solder bridge causes the reliability of soldering to be impaired.
- Solder bridges are likely to occur when the surface tension of the flux is high. A flux having a high surface tension does not easily spread in a direction horizontal to the substrate, and tends to stay between the electrodes when the solder is melted. Adjacent molten solder is attracted by the flux between the electrodes, and when the solders stick together, they form a bridge.
- Patent Document 1 discloses a flux composition containing a rosin ester surfactant or an amide surfactant.
- Patent Document 2 discloses a brazing flux containing a cationic surfactant and a nonionic surfactant.
- the conventional flux has a problem that even if it contains a surfactant, if the electrode pitch is further narrowed, the bridge of the solder cannot be suppressed and a bridge is generated.
- the present invention solves such problems, and provides a flux that can suppress bridging even for electrodes having such a narrow pitch that solder bridging occurs with conventional fluxes. For the purpose.
- the technical means of the present invention taken in order to solve the above-mentioned problems are as follows. (1) 15% by mass to 35% by mass of polyoxyalkyleneethylenediamine, 2% by mass to 15% by mass of organic acid, 10% by mass to 30% by mass of base material, and 3% by mass to 30% by mass of amine

- the polyoxyalkyleneethylenediamine is at least one of polyoxypropyleneethylenediamine, polyoxyethyleneethylenediamine, polyoxymethylethyleneethylenediamine, or polyoxyethylenepolyoxypropyleneethylenediamine, as described in (1) above Flux.
- FIG. 2 is an enlarged photograph of a flux residue after soldering in Example 1.
- FIG. 4 is an enlarged photograph of a flux residue after soldering in Comparative Example 1. It is an enlarged photograph of the flux residue after the soldering of the comparative example 3.
- the flux of the present embodiment contains polyoxyalkylene ethylenediamine, organic acid, base material, amine and solvent.
- Polyoxyalkylene ethylenediamine is a surfactant.
- Polyoxyalkylene ethylenediamine is represented by the following chemical formula.
- R1 to R4 represent side chains.
- polyoxyalkylene ethylenediamine two polyoxyalkylene groups are bonded to N atoms at both ends of ethylenediamine.
- the polyoxyalkylene ethylenediamine used in the present embodiment is added in an amount of 15% by mass to 35% by mass, and examples of the polyoxyalkylene ethylene diamine include polyoxypropylene ethylene diamine, polyoxyethylene ethylene diamine, polyoxymethyl ethylene ethylene diamine, or polyoxy It is preferably at least one of ethylene polyoxypropylene ethylenediamine.
- polyoxypropylene ethylenediamine two polyoxypropylene groups are bonded to N atoms at both ends of ethylenediamine.
- polyoxyethylene ethylenediamine two polyoxyethylene groups are bonded to N atoms at both ends of ethylenediamine.
- polyoxymethylethyleneethylenediamine two polyoxymethylethylene groups are bonded to N atoms at both ends of ethylenediamine.
- polyoxyethylene polyoxypropylene ethylenediamine at least one polyoxypropylene group and at least one polyoxyethylene group are bonded to four side chains R1 to R4 bonded to ethylenediamine in total.
- Organic acid is added in an amount of 2% by mass to 15% by mass as an activator component in the flux.
- organic acid glutaric acid, succinic acid, adipic acid, azelaic acid, glycolic acid, diglycolic acid, thioglycolic acid, thiodiglycolic acid, malic acid, tartaric acid and the like are used.
- the base material is added in an amount of 10% by mass to 30% by mass, and polyethylene glycol, polyoxyethylene polyoxypropylene copolymer or the like is used as the base material.
- the amine is added in an amount of 3% by mass to 30% by mass as an activator component in the flux.
- the amine include polyoxyalkylene diamines such as polyoxyethylene diamine, polyoxypropylene diamine, and polyoxyethylene polyoxypropylene diamine, polyoxypropylene glycol triamine, N, N, N ′, N′-tetrakis (2-hydroxy Propyl) ethylenediamine, N, N ′, N′-polyoxyethylene-tallow-1,3-diaminopropane, N, N ′, N′-polyoxyethylene-alkyl-1,3-diaminopropane, diethanolamine, triethanol
- examples include amines, diisopropanolamine, and triisopropanolamine.
- Solvent is added in an amount of 20% by mass to 40% by mass to dissolve the solid content in the flux.
- the solvent is selected from generally known glycol ether compounds.
- the solvent preferably does not volatilize at a low temperature range of 120 ° C. to 150 ° C. in order to efficiently bring about the action of the activator.
- the boiling point of the solvent is preferably 200 ° C. or higher.
- the solvent hexylene glycol, 2-ethylhexyl diglycol, phenyl glycol, butyl triglycol and the like are used.
- additives for the above-mentioned flux for example, a resin, a thixotropic agent, a colorant and the like may be appropriately added within a range that does not impair the performance of the flux.
- Example 9 contains 20% by mass of base material, 5% by mass of organic acid, 10% by mass of amine, 30% by mass of polyoxyethylene polyoxypropylene ethylenediamine, and 35% by mass of solvent. In all of Examples 1 to 9, bridging between the electrodes was suppressed.
- Example 1 As shown in FIG. 1, in Example 1, as described above, bridging between the electrodes was suppressed after soldering.
- the solder balls are mounted on the substrate 3 and the flux of Example 1 is applied.
- the flux of Example 1 is liquefied by heating at the time of reflow and becomes in a low surface tension state. If the heating is further continued, the flux further spreads. Because the flux spreads thinly, the molten solder does not approach or stick to each other. Therefore, the solder 11B solidified after melting does not become a bridge.
- bridging is suppressed as in the first embodiment.
- bridging was suppressed because the flux of Examples 1 to 9 contained polyoxypropylene ethylenediamine or polyoxyethylene polyoxypropylene ethylenediamine in the above-described range, and thus liquefied flux during reflow. This is presumed to be due to thin and wet spreading.
- Comparative Example 1 contained polyoxyethylene octadecylamine ether, and a bridge was generated between the electrodes.
- Comparative Example 2 contained polyoxyethylene stearylamide, and a bridge was generated between the electrodes.
- Comparative Example 3 did not contain a surfactant, and a bridge was generated between the electrodes.
- FIG. 4A to 4C show the bridge generation process of Comparative Example 1.
- FIG. 4A in a step before reflow, solder balls 21 are mounted on the substrate 3A, and the flux 22 of Comparative Example 1 is applied.
- the flux 22 of Comparative Example 1 is liquefied as shown in FIG. 4B. Since the substrate 3A has a narrow pitch and the liquefied flux 22 has a high surface tension, the fluxes 22 gather together and rise on the substrate 3A to form a flux pool 22A. Since the flux pool 22A is formed, the molten solder 21A is attracted to the flux pool 22A. When the solder 21A is attracted, the adjacent solders 21A approach each other.
- the adjacent solders 21A adhere to each other, and become a solder bridge 21C as shown in FIG. 4C.
- a residue 22B remains on the substrate 3A.
- the flux pool 22A is formed in the same manner as in Comparative Example 1, so that solder bridges 21C and 31C are generated and residues 22B and 32B remain.
- Examples 3 and 9 and Comparative Examples 1 and 2 all have the same composition ratio of the base material, the organic acid, the amine and the solvent, and all contain 30% by mass of a surfactant, In Examples 3 and 9, bridging could be suppressed, but in Comparative Examples 1 and 2, bridging could not be suppressed.
- Examples 3 and 9 and Comparative Examples 1 and 2 have different types of surfactants contained therein.
- Example 3 contains polyoxypropylene ethylenediamine
- Example 9 contains polyoxyethylene polyoxypropylene ethylenediamine
- Comparative Example 1 contains polyoxyethylene octadecylamine ether
- Comparative Example 2 contains polyoxyethylene stearylamide. .
- polyoxypropylene ethylenediamine or polyoxyethylene polyoxypropylene ethylenediamine is used as an example of polyoxyalkylene ethylenediamine, but other polyoxyalkylene ethylenediamines can similarly suppress the bridge.
- the flux obtained by replacing the polyoxyethylene polyoxypropylene ethylenediamine of the flux of Example 9 with polyoxyethylene ethylenediamine or polyoxymethylethyleneethylenediamine had the same result as the flux of Example 9.
- content of a base material, an organic acid, an amine, and a solvent is not restricted to the quantity described above.
