Solder pastes


No clean solder paste for the electronics with metal alloy component,
lead-free and halide-free activators. (WEEE/RoHS-compliant)
low-melting // ANSI/J-STD-004 (IPC-TM-650): ROL0

Packaging units:
50 g bottle with brush
Application area: Repair work on circuit boards, tinning of components


This liquid solder paste (lead-free) with metal alloy component SnAg 0.4 Bi 57.6 (>80%) has been developed for repair work on circuit boards and components.
It is low-viscous and is 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 normally applied with a brush, but can also be applied individually.

The processing of EO-FLP-005 can be carried out using hot-air or soldering iron. Important information: This paste must be stirred before use!

Customer added value:

  • Low-melting (melting point of solder: 137°C, working temperature 190-350°C)
  • 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 odour, hardly any development of vapours


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 previously described.
