Description

EO-G-011C is a no-clean flux, universally suitable for wave and selective soldering of printed circuit boards and contains organic, halogen-free and resin-free, activating additives specially adapted to the soldering processes. This flux has been developed in a combination with lead and lead-free solders specially adapted to the thermal requirements of the soldering process.

EO-G-011C is based on a novel formulation to stabilize and improve the application process and residue behaviour compared to conventional water or partially water based fluxes. This flux leaves no sticky residue.
EO-G-011C is a water-based electronic flux and non-corrosive. The solids content is 4%.

Customer added value

  • Non-flammable (no legal restrictions for transportation, storage and handling)
  • Very good soldering properties (capillarity, wetting)
  • Broad process window (high thermal stability, good activity over a long interval)
  • Very good residue behavior (optically clean, high SIR)

Recommendations for the processing of this flux:

This flux must be applied by spraying. After application, it is advisable to dry the flux in order to transform the liquid into fusible phase which favours the soldering operation.

Foam fluxes: Not recommended

Spray fluxing: If dosing is possible, first set the flux quantity to 15 – 20 ml/min, observe the even flux distribution on the PCB (test with thermal paper if necessary) and then correct to the optimum quantity.

Preheating: For “simple” PCBs a preheating temperature of 80 – 110 °C is recommended, for “more complex” PCBs 110 – 130 °C on the top side of the PCB. It can be used in both leaded and lead-free solder systems.
