The present disclosure, in one aspect, relates to: comprises a solvent (component A) and HansenAn amine (component B) having a solubility parameter with a polarity term (δ p) of 7.8 or less and a diphosphonic acid (component C) represented by the following formula (VI); or a cleaning agent composition for removing flux residue, which is prepared by mixing the component A, the component B and the component C.
Description
Technical Field
The present disclosure relates to a cleaning agent composition for removing flux residue, a cleaning method using the cleaning agent composition, and a method for manufacturing an electronic component.
Background
In recent years, in mounting electronic components on printed wiring boards and ceramic substrates, from the viewpoint of low power consumption and high-speed processing, the size of the components has been reduced, and the gap to be cleaned in cleaning the solder flux has been narrowed. In addition, lead-free solder has come to be used from the viewpoint of environmental safety, and rosin-based flux has come to be used in association therewith.
For example, international publication No. 2011/027673 (patent document 1) discloses a cleaning agent for removing a water-soluble flux of lead-free solder, which contains 5 to 100 parts by weight of a glycol ether compound per 100 parts by weight of water.
International publication No. 2005/021700 (patent document 2) discloses a cleaning agent for removing solder flux, which is characterized in that: the content of benzyl alcohol is set to be 70-99.9 wt% and the content of amino alcohol is set to be 0.1-30 wt% when the content of diol compound is less than 1 wt% relative to the total amount, and the content of benzyl alcohol is set to be 15-99 wt% and the content of amino alcohol is set to be 0.1-30 wt% when the content of diol compound is 1-40 wt%.
Japanese patent laid-open No. 2004-2688 (patent document 3) discloses an aqueous cleaning composition which contains 5 to 30% by weight of an organic solvent, 5 to 30% by weight of a glycerin ether having an alkyl group or alkenyl group having 4 to 12 carbon atoms, and 5% by weight or more of water and is used for precision parts such as metal parts, electronic parts, semiconductor parts, and liquid crystal display panels.
Japanese patent laid-open publication No. 2018-21093 (patent document 4) discloses the following cleaning agent composition for screen printing plates: the composition comprises an amine or a salt thereof having a solubility of less than 10g in 100g of water at 25 ℃, a solvent having a solubility of 0.02g or more and less than 10g in 100g of water at 25 ℃, and water, wherein the amine is at least one selected from the group consisting of primary amines, secondary amines, and tertiary amines having 6 or more and 26 or less carbon atoms.
Disclosure of Invention
The present disclosure relates, in one aspect, to a cleaning agent composition for removing flux residue, which contains a solvent (component a), an amine (component B) having a hansen solubility parameter with a polarity term (δ p) of 7.8 or less, and a diphosphonic acid (component C) represented by the following formula (VI), or a cleaning agent composition for removing flux residue, which contains the component a, the component B, and the component C.
[ chemical formula 1]
In the formula (VI), X is an alkylene or hydroxyalkylene group having 1 to 6 carbon atoms.
The present disclosure relates, in one aspect, to a cleaning method including a step of cleaning an object to be cleaned having flux residue with the cleaning agent composition of the present disclosure.
In one embodiment, the present disclosure relates to a method for manufacturing an electronic component, including the steps of: at least one step selected from a step of mounting at least one component selected from a semiconductor chip, a chip-type capacitor, and a circuit board on the circuit board by soldering using a flux, and a step of forming a solder bump for connecting the component and the like on the circuit board; and a step of cleaning at least one selected from a circuit board on which the component is mounted and a circuit board on which the solder bump is formed by the cleaning method of the present disclosure.
Detailed Description
In recent years, the size of a semiconductor package substrate has been reduced, solder bumps have been miniaturized, and a gap between the solder bumps and a component to be connected has been narrowed. Further, since the solder bumps are miniaturized and the gap between the solder bumps and the members to be connected is narrowed, the cleaning agent composition disclosed in the above patent document is insufficient in removability of flux residue (flux removability) and is not satisfactory in cleanability. Further, the cleaning agent composition is also required to have improved removability (tin removability) for tin oxide and tin salt generated during reflow soldering. In addition, a stable liquid state that does not separate is required for the cleaning agent composition.
Accordingly, the present disclosure provides a cleaning agent composition for removing flux residue, which ensures a stable liquid state and is excellent in flux removability and tin removability, a cleaning method using the same, and a method for manufacturing an electronic component.
According to the present disclosure, a cleaning agent composition for removing flux residue, which ensures a stable liquid state and is excellent in flux removability and tin removability, can be provided.
The present disclosure is based on the following recognition: a stable liquid state is ensured and flux removability and tin removability are improved as compared with the conventional one by using a cleaning agent composition containing a specific solvent (component A), a specific amine (component B) and a specific diphosphonic acid (component C) or a cleaning agent composition containing component A, component B and component C.
That is, the present disclosure relates, in one or more embodiments, to a cleaning agent composition for removing flux residue containing a solvent (component a), an amine (component B) having a hansen solubility parameter with a polarity term (δ p) of 7.8 or less, and a diphosphonic acid (component C) represented by the above formula (VI), or a cleaning agent composition for removing flux residue containing component a, component B, and component C (hereinafter, these are also collectively referred to as "the cleaning agent composition of the present disclosure"). In accordance with the present disclosure, in one or more embodiments, flux residue may be removed with good efficiency. In addition, according to the present disclosure, in one or more embodiments, tin oxide and tin salt generated during reflow soldering can be efficiently removed. Further, according to the present disclosure, in one or more embodiments, a highly stable, uniform and transparent cleaning agent composition for removing flux residue can be obtained.
The mechanism of action of the effect of the detergent composition of the present disclosure is not yet clarified in detail, but is presumed as follows.
That is, in the cleaning agent composition of the present disclosure, the component a (solvent) penetrates the flux and the flux residue deteriorated by reflow or the like to reduce the viscosity and make the flux easily flowable, and the component B (amine) functions to decompose or hydrophilize the flux and the flux residue and make the flux and the flux residue easily soluble in the cleaning agent composition.
It is also presumed that the solubility in water in the washing step after washing of the flux and the flux residue is increased by the component B (amine), the flux removability by washing is improved, and the flux residue remaining after washing and washing can be reduced.
Further, when the component B and the component C form a salt in the cleaning agent composition of the present disclosure, the salt of the component B (amine) and the component C (diphosphonic acid) having a high affinity with tin acts on tin oxide and tin salt which are generated by reflow soldering and adhere to the flux residue and the object to be cleaned, and is easily dissolved in the cleaning agent composition. It is also presumed that the solubility of tin oxide or tin salt in water in the rinsing step after washing is increased by the salt of component B and component C, so that the tin removability is improved, and the residual amount of tin oxide or tin salt after washing and rinsing can be reduced.
Further, it is presumed that, as for the salt of the component B and the component C, by setting the polarity term (δ p) of the hansen solubility parameter of the component B (amine) to 7.8 or less, the salt with the component C (diphosphonic acid) can be dissolved in the component a (solvent), and a uniform and stable detergent composition can be obtained.
However, the present disclosure is not limited to this mechanism and can be explained.
The "flux" in the present disclosure refers to a rosin-based flux containing rosin or rosin derivatives used in soldering for removing oxides that inhibit the connection between metals such as electrodes and wires and solder metals and promoting the connection, and a rosin-free water-soluble flux, and the "soldering" in the present disclosure includes soldering by a reflow method and a flow soldering method. By "solder flux" in this disclosure is meant a mixture of solder and flux. In the present disclosure, "flux residue" refers to residue derived from a flux remaining on a substrate after solder bumps are formed using the flux and/or a substrate after soldering is performed using the flux. For example, when other components (for example, a semiconductor chip, a chip capacitor, another circuit board, and the like) are stacked and mounted on a circuit board, a space (gap) is formed between the circuit board and the other components. The flux used for the mounting also remains in the gap as flux residue after soldering by reflow soldering or the like. In the present disclosure, the term "cleaning agent composition for removing flux residue" refers to a cleaning agent composition for removing a flux residue after forming a solder bump and/or soldering using a flux or a solder flux. In terms of the remarkable effect of the cleanability based on the cleaner composition of the present disclosure being exhibited, the solder is preferably a tin-containing lead (Pb) -free solder.
In the present disclosure, Hansen solubility parameter (hereinafter also referred to as "HSP") is a value published by Charles m.hansen in 1967 for predicting the solubility of a substance, and is a parameter based on the viewpoint of "2 substances having similar intermolecular interactions are easily dissolved in each other". HSP contains the following 3 parameters (units: MPa)0.5)。
δ d: energy based on intermolecular dispersion force
