WebA way to experimentally determine wetting is to look at the contact angle (θ), which is the angle connecting the solid–liquid interface and the liquid–gas interface (as in the figure). If θ = 0°, the liquid completely wets the substrate. If 0° < θ < 90°, high wetting occurs. If 90° < θ < 180°, low wetting occurs.
WebIf a solder tip is left hot without a covering, it can react with oxygen and lead to improper wetting. High or low soldering temperatures.
