Abstract

Abstract: Maleic acid monodehydroabietyl ester(MAMDE) was synthesized with dehydroabietic acid and maleic anhydride as starting materials. And the structure of MAMDE was characterized by means of ATR-FTIR, ¹H NMR and MS. Dehydroabietic acid was transformed into dehydroabietic alcohol through LiAlH4 reduction reaction, and the MAMDE was obtained after the dehydroabietic alcohol reacted with maleic anhydride. The physical performance of MAMDE based flux (25% content) was tested and the soldering ability to Sn37Pb, Sn0.7Cu and Sn3.0Ag0.5Cu solder alloys were studied by using the spreading ratio method. The results showed that the physical stability, dryness and corrosivity to copper plate of MAMDE based flux, and the surface insulation resistance after welding were all met the standard, the expansion rates of Sn37Pb, Sn0.7Cu and Sn3.0Ag0.5Cu were 76.6%, 81.6% and 75.3%, and the soldering ability was better than refined hydrogenated rosin (RHR) based flux under the same condition. Sn37Pb and Sn0.7Cu solder alloys showed neater and brighter welding spots by using the MAMDE based flux compared to those by using refined hydrogenated rosin.

Key words: maleic acid monodehydroabietyl ester, refined hydrogenated rosin, flux, SnPb solder alloy, lead-free solder alloy
