    Why is it advantageous to remove solder by 3S-Wick®?

    Wicking avoids damaging and life reducing heat shocks to components, printed circuit boards copper tracks (peel off danger if overheated) and surrounding components. Wicking also protects these parts against excessive temperatures of idling mechanical solder suckers. 3S-Wick® is made from high heat conductive copper. The cold 3S-Wick® end is pressed with the hot soldering iron tip on solder ot be absorbed. The cold wick and cold solder increase now gradually in temperature. There is no sudden teperature increase with large temperature gradients causing exteme thermal stress. When wick and solder rise to the melting temperature range of solder, the solder liquefies and is almost instantaneously drawn by capillary forces into the wick, like ink into a blotter. Wick and tip are now simultaneously lifted. The wick end with the absorbed solder is cut off preparing for the next de-solder operation.

    3S-Wick® is made from high heat conductive copper and protects therefore against those "deadly" hot idling iron tip temperatures.
    The extreme heat conductive copper of 3S-Wick® naturally cools down the solder tip.
    Too small a solder tip in comparison to the 3S-Wick® size will cause the temperature to drop too low. The resulting temperature of the wick end, solder and tip might even fall under the melting point of the solder. Naturally suck a combination will not give a satisfactory result. If the temperature drops below the melting temperature then it will rise only slowly by the wattage heating of the iron. The de-soldering operates slowly. The size of tip should be capable of storing sufficient heat to result in a temperature above melting point. Wicking uses the stored heat in the tip to permit quick heat up of the cold wick and solder. The stored heat should permit sufficient temperature increase of wick and solder to give a continuous, undelayed one-cycle de-soldering.

    3S-Wick® technology provides the fast flux response to permit capillary forces undelayed action.
    De-soldering by wicking means actually soldering the wick with the unwanted solder, removing it from one place into the wick end. The solderability of the wick is therefore a direct quality indicator. How do you test solderability to compare differnt makes of wick?
