ELSOLD SIMIOO(Ag) MA Solder Micro-alloyed lead free solders Good wetting properties Smooth and shiny surface Reduced copper leaching Description ELSOLD SN1 OO(Ag) MA solders are designed to replace commercially available tin/lead alloys by lead-free alloys in existing production processes of electronic manufacturing with the pretension to improve properties of lead-free alloys. ELSOLD SNIOO(Ag) MA solders provide the lowest leaching rates for Copper. SAC305 is the mostly accepted alloy of the SnAgCu group. Elowever, high metal prices have caused introduction and increasingly interest in solders with lower or no silver contents, which provide good results in many applications at lower cost. Application As it is the case for lead-free alloys, changes of the temperature profile at the soldering equipment are required for ELSOLD SNIOO(Ag) MA solders as well. Typical soldering temperatures are in the range of 255 - 265 °C (up to 320 °C for selective soldering). The quality of the resulting solder joints is in many aspects comparable to traditional SnPb and conventional lead free solders. Physical properties are not changed by the micro-alloy additions (Co, Ni, Ce). The differences between non-micro-alloyed and ELSOLD SNIOO(Ag) MA are as follows: ■ Finer grains, resulting in smoother and shinier surface, caused by changed solidification behaviour ■ Clearly reduced copper leaching ■ Extended useful life of the solder baths due to reduced copper absorption ■ Reduced wear on the soldering equipment Storage/Shelf Life The material can be stored for a minimum of 60 months from the date of manufacturing. Care should be taken, however, to store the material in a clean environment. Using the material beyond the official shelf life is possible without any problem in most cases. Elowever, this should be confirmed by adequate trials before actual usage. Health and Safety ELSOLD SNIOO(Ag) MA solder alloys are not considered to be harmful. Information relating to health and safety should be taken from the respective material safety data sheet.
