Description

This flux has been specially developed for solar technology, in particular for soldering solar modules, tabber and stringer material
as well as connecting cells. EO-S-011 is a No Clean-Flux, halogen-free formulated and optimized for use in wave, selective and manual soldering processes. EO-S-011 leaves no sticky residue. The activators are specially designed for the higher temperatures that are required in the
manufacture of solar modules, without affecting their effectiveness. The application can be carried out by any usual application method (except foams). The solids content is 2.0 wt.-%. EO-S-011 is totally free from corrosion action.

Instructions for use:
Sprayfluxing: If possible, try at first a quantity of 30 – 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, layout etc. In case of using lead-free solders, preheating temperatures of 100 – 140 °C on the topsides are possible.

Safety instructions: Please refer to the current MSDS
This flux is very versatile and OPS-compatible. There are good results for manual, wave and selective soldering, as well as for cable assembly / wire tinning. The general rule of applying fluxes applied in principle as low as possible also applies to this product
