Title: Method for partial or complete coating of metal surfaces with solder and bonding agent
Inventor: SUCKE NORBERT-WILLIAM DIPL PHY
IPC: B23K1/00
Filed: 1997-10-10
Abstract: The bonding agent is applied in exactly measured, preferably toleranced amounts in a process step separately from application of the solder. The method consists of the following steps:  a) at a bonding agent station (18) the bonding agent is applied to the metal surface (17);  b) at a powder station (19) the layer of the bonding agent is covered by solder powder;  c) at a hardening station (20) the layer consisting of the bonding agent and the solder is hardened; d) surplus solder is blown away at a blower station (21);  e) after this a detector station (22) is used for control of the coating process. Alternatively the solder powder is applied first, followed by application of the bonding agent, and removal of the surplus solder and flux. The concentration of the materials in the layer is checked by a detector, and finally the layer is hardened. Only solder is applied at the powder station (19). Flux is applied at a last process step, and is bonded to the solder and bonding agent layer by means of heat. Alternatively a mixture of solder and flux powders is applied at the station (19). Additionally such a mixture can include constituents which improve the corrosion and/or wear resistance of the layer. A pressure roller is used before the hardening station (20) to press the solder powder to the bonding agent. Polyacrylate with a hardening temperature of 150  deg C is used as the bonding agent. The solder consists of a mixture of aluminum and silicon. Alternatively it consists of pure silicon.
