EO-B-013 is a powerful NO-CLEAN flux. Alcohol-based with di-carboxylic acids and synthetic resin.
This flux has been developed for wave processes, as well as for dip soldering processes and strand tinning. It can be applied with all common application processes (except foaming).

Recommendations for the processing of this fluxing agent:
This flux is very versatile in use, good results have been achieved both with wave soldering and special applications. The general rule to apply as little quantity of flux as possible, is also applicable for this product.

Spray fluxes: With the dosing option quantify the flux, first set to 15 – 30 ml/min., observe the even distribution of flux on the circuit board (if necessary test with heat-sensitive 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 lead as well as those that are lead-free.
