Component with a surface to be soldered

摘要

The invention relates to a surface of an object, especially a heat exchanger, e.g. a lateral part, a wavy rib, or a tube of a heat exchanger, which is to be soldered by means of a flux layer (2). In order to improve the properties of the surface that is to be soldered, said surface is provided with at least one more layer (3; 13, 16) in addition to the flux layer (2). The at least one more layer (3; 13; 16) contains an additive which modifies the surface to be soldered, said additive being reacted in order to modify the surface when the surface that is to be soldered is soldered.
