Abstract:
Provided is a flux, flux residue of which keeps a predetermined viscosity during reflow and after a reflow step without hindering wettability of a solder alloy, the flux being compatible with an underfill in an underfill hardening step. The flux contains a thermosetting resin, a hardening agent, an organic acid and a solvent in which the flux contains 3% or more by mass to 8% or less by mass of the resin, 1% or more by mass to 5% or less by mass of the hardening agent to remain within a limit of an additive amount of the resin, 5% or more by mass to 15% or less by mass of the organic acid and a remainder of the solvent.

Claim (Index 1):
A flux comprising:\n a thermosetting resin; a hardening agent; an organic acid; and a solvent, wherein the organic acid is a long-chain dibasic acid mixture in which long-chain dibasic acids having the following compositions (1) through (4) are respectively mixed at a predetermined ratio thereof, 2-Methylnonanedioic acid, 30% to 60% by mass; 4-(Methoxycarbonyl)-2,4-dimethylundecanedioic acid, 8% to 20% by mass; 4, 6-bis(Methoxycarbonyl)-2,4,6-trimethyltridecanedioic acid, 8% to 20% by mass; and 8,9-bis(Methoxycarbonyl)-8,9-dimethylhexadecanedioic acid, 15% to 30% by mass, the ratios of the long-chain dibasic acids having the compositions (1) through (4) are as follows when the entire of the long-chain dibasic acid mixture is set to be 100%, and the flux contains 3% or more by mass to 8% or less by mass of the resin, 1% or more by mass to 5% or less by mass of the hardening agent to remain within a limit of an additive amount of the resin, 5% or more by mass to 15% or less by mass of the long-chain dibasic acid mixture and a remainder of the solvent.
