In selective solder machines, solders with a phosphor content leads to passivation of the wettable nozzles. FELDER electronics solder Sn99Ag+ - PHOSPHOR-FREE contains definetely no phosphor. Lead-free solderings in the industrial component manufacturing as well as high-temperature applications e.g in the automotive industry (good temperature change stabilty at high temperatures). Minimum long-term temperature stability up to 120°C. Also usable in older wave soldering machines which crucible and nozzles were still manufactued of V2A and do not provide innert gas. The experience of our customers shows that in most cases innert gas is not necessary. Besides of the known advantages of the Ni-endowed solders, by adding germanium our alloys achieve improved wetting properties on all common surfaces in the electronics manufacturing and minimal dross formation compared to all other lead-free solders. A special advantage is the low deallyoing rate of copper (compared to common SnAgCu-alloys 5 times lower). The low silver addition of 0.3 % in "Sn99Ag+" has no negative effect on the corrosive influence on stainless steel components. Futhermore, the Ag-addition leads to an additional reduction of the working temperature, an improved passage at THT applications und to a better wetting of the solder joint.
