Soldering
Lead-free or leaded soldering: processes and solders
Depending on the customer's wish we solder SMD assemblies lead-free or leaded. We solder THT lead-free, and in selective soldering the standard is the lead-free solder SN100C.
The processes at a glance
| Process | Solder |
|---|---|
| SMD, reflow | lead-free or leaded, as the customer wishes |
| THT, wave soldering | lead-free |
| Selective soldering | by default SN100C (lead-free), conversion to leaded solder if required |
Environmental and RoHS directives
Our processes comply with current environmental and RoHS directives.
