    摘要: The invention relates to a method for shortening the process time during the soldering of electric or electronic components by means of electromagnetic induction heating, in particular the soldering of electric contact elements to solder connection surfaces that are applied to a non-metallic substrate, in particular a pane of glass. According to the invention, an electric contact element is first produced, designed as a solder foot, made of a material with an iron-nickel or iron-chromium alloy base. Subsequently, a lead-free connecting material is applied to the solder foot. After the solder foot has been positioned on the respective solder connection surface, the solder foot is inductively heated by means of high frequency energy with increased heating of the solder foot material and reduced heating of the silver-containing material of the respective solder connection surface. The soldering stage is completed after a time of

    摘要: Provided is a flux which can remove metal oxides to improve solder wettability and can fix the object to be soldered with flux residue. The flux contains thermosetting resin, and long-chain dibasic acid mixture including one or more species of first long-chain dibasic acid having an alkyl group in a side chain, the first long-chain dibasic acid being added as a hardening agent for hardening the thermosetting resin and an activator, and second long-chain dibasic acid having an alkyl group and an alkoxycarbonyl group in a side chain and having carbon number of 8 or more in a main chain between the carboxyl groups at opposite terminals. It is preferable that content of the thermosetting resin is 30 % through 70 % and content of the long-chain dibasic acid mixture is 20 % through 60 %.

    摘要: Problem: Even if the strength of a solder composition close to a SnBi eutectic composition was improved, it was brittle, so when it was used for small electronic devices such as mobile phones or notebook computers, the resistance to drop impacts when the small electronic equipment was dropped was low. Therefore, interface peeling often took place between the soldered surface and a printed circuit board, resulting in the devices being destroyed.
    Means for Solving the Problem: When soldering using a solder paste containing a SnBi-based low-temperature solder, at least one type of solder composition selected from a Sn-Ag, a Sn-Cu, and a Sn-Ag-Cu solder composition is diffused into the solder paste by simultaneously supplying at least one type of preform selected from a Sn-Ag, a Sn-Cu, and a Sn-Ag-Cu solder composition, whereby resistance to drop impacts is improved.
