Description
EO-B-023A is a No Clean flux of the latest generation. This multi-flux was developed for wave, selective and hand soldering processes and contains special highly effective activators that additionally strengthen the soldering process. It can be applied using all standard application methods (except foaming). The solids content is 2 wt.-% and is corrosion-free. Additional information on the ingredients (hazardous substances), safe handling, storage, transportation and disposal can be found in the current safety data sheet (SDS, SDS, MSDS). This flux is very versatile and OSP-compatible. Good results have been achieved in manual, wave and selective soldering as well as in cable assembly/strand tinning. The generally applicable rule that applied flux quantities should always be as low as possible also applies to this product.
Spray fluxing: With the dosing option quantify the flux, first set to 30 – 40 ml/min., observe the even distribution of flux on the circuit board (if necessary test with heatsensitive paper) and then adjust to the optimal quantity.
Preheating: With “simple” circuit boards a preheating temperature of 80 – 110 °C is recommended on the top side of the circuit board, with “more complex” boards from 100 – 130 °C. The flux can be used both in systems containing leades as well as those that are lead-free.
