Application area: Repair work on circuit boards, tinning of components


These rework paste (lead-free) with metal alloy component [Sn 96.5 Ag 3.0 Cu 0.5] (>85%) have been developed for repair work on circuit boards
and components and are distinguished, among other things, by a high level of activity as well as good wetting and spread.
Due to these properties the paste should be applied sparingly. The paste is applied with a dosing syringe via a metal dosing needle.
This enables a precise dosing resp. positioning of the paste.

The processing of the rework paste can be carried out using hot-air or soldering iron.

Customer added value:

  • Highly effective
  • Perfect soldering results
  • Very wide process window
  • Versatile application possibilities
  • Economical in use
  • Contaminated pads and pins are also activated
  • No crystal formation, paste remains homogeneous and stable
  • Careful and targeted dosing
  • Low odor, hardly any development of vapors


In individual cases, which must be checked by the user, the wave soldering of critical components can also be supported with this paste.
The paste is applied as described.
