BRAZING CREAM, PROCESS FOR PREPARING SUCH A BRAZING CREAM, AND BRAZING METHOD USING THE SAME

摘要

The invention relates to a solder cream containing, in a vehicle, particles of a brazing metal alloy having a melting temperature of 260 ° C or less, and metal formate particles having a lower decomposition temperature or equal to the melting temperature of the brazing metal alloy plus 30 ° C. Depending on the metal formate used, this solder cream can be used at a lower brazing temperature, or the solder that it allows to form has an increased resistance to tearing stresses at the brazing temperature. This solder cream is especially of great interest for the manufacture of double-sided electronic cards.
