Dickmann soldering technical guides: choosing alloy, format and process
The Dickmann technical guides bring together in one place the information needed to choose alloy, format and process: compositions, melting temperatures, reference standards and typical applications. They are designed for engineering departments, purchasing, EMS providers, installers and craftsmen. Start from the process you use, or from the alloy or product you know: each guide links to the related alloys and products.
Lead-free alloys
RoHS-compliant lead-free alloys for electronics and industry
Lead-free alloys: selection guide
Overview of lead-free alloys and the right alloy for each process.
SAC305 alloy
Sn96.5/Ag3/Cu0.5, 217–220 °C: the reference alloy of the electronics industry.
Low-silver SAC0307 alloy
Sn99/Ag0.3/Cu0.7: costs less than SAC305 in wave, selective and HASL.
SAC405 alloy
4 % silver for highly stressed joints, when the specification calls for it.
Sn-Cu tin-copper alloys
Sn99.3Cu0.7 for electronics, Sn97Cu3 for copper pipes.
99SnCuNiGe (SN100C equivalent)
Silver-free Sn-Cu-Ni-Ge alloy, eutectic at 227 °C.
Leaded and special alloys
For applications where lead is still permitted
