Description

EO-B-026A is a flux of the latest generation. It is a high-performance No Clean-Flux based on alcohol with di-carboxylic acid activator complex and rosin. This flux was used for selective and wave soldering processes, as well as for dip soldering process and cable-strands-tinning developed. This variant was specially developed for full-tunnel nitrogen applications and guarantees significantly better soldering results than conventional adipic acid solutions under full nitrogen thanks to a wide process window and high temperature stability. The application can be carried out by any usual application method (except foams). EO-B-026A is totally free from corrosion action.

Customer added value

  • Wide range of applications
  • Very good soldering properties (capillarity, wetting)
  • Virtually residue-free despite higher solids content
  • Best soldering results even with outdated or overlapping PCBs and components
  • Wide process window (very high thermal stability, very good activity over a very long interval)
  • Successful passing of internal test (SIR selective)
  • Best results, especially with OSP and ENIG soldering surfaces

Instructions for use:
This flux is very versatile and OPS-compatible. There are good results for manual, wave and selective soldering. The general rule of applying fluxes applied in principle as low as possible also applies to this product.

Recommendation from practice:
Spray fluxing: If possible, try at first a quantity of 25 – 50 ml/min. and observe the distribution of the flux. After that, correct the quantity. Air-pressure: 18 – 20 l/min.

Preheating (if preheating system is used): Entering the solder-wave, the temperature on the topside of the pasteboards should be 80 – 110 °C, dependent on type of boards, lay-out etc. In case of using lead-free solders, preheating temperatures of 100 – 130 °C on the topsides are possible.
