EO-B-026 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. The application can be carried out by any usual application method (except foams). EO-B-026 is totally free from corrosion action.
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:
Sprayfluxing: If possible, try at first a quantity of 15 – 30 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.
