Latest Patents

Uehata holds a patent for a flux that effectively removes metal oxides to enhance solder wettability. This invention also allows for the fixation of the object to be soldered with flux residue. The flux comprises a thermosetting resin and a long-chain dibasic acid mixture. This mixture includes a first long-chain dibasic acid with an alkyl group in its side chain, which serves as a hardening agent for the thermosetting resin. Additionally, it contains a second long-chain dibasic acid that has both an alkyl group and an alkoxycarbonyl group in its side chain, with a carbon number of eight or more in the main chain between the carboxyl groups at opposite terminals. The optimal content of the thermosetting resin is between 30% and 70%, while the long-chain dibasic acid mixture should be between 20% and 60%.
