Solder paste

Disclosed is a solder paste that includes, within a flux, an activator that has: a dibasic acid with a molecular weight of no more than 250, a monobasic acid with a molecular weight in the range of 150 to 300, and a dibasic acid with a molecular weight in the range of 300 to 600; and at least one re...

Beschreibung
Zusammenfassung:	Disclosed is a solder paste that includes, within a flux, an activator that has: a dibasic acid with a molecular weight of no more than 250, a monobasic acid with a molecular weight in the range of 150 to 300, and a dibasic acid with a molecular weight in the range of 300 to 600; and at least one resin additive that is selected from among the group comprising high-density polyethylenes and polypropylenes. The solder paste has in the range of 4 wt% to 12 wt% resin additive within the flux, and the viscosity of the solder paste at 80°C is at least 400 Pa·s.
