ECSS-Q-ST-70-08C - Manual soldering of high-reliability electrical connections (6 March 2009)

Definition

angle enclosed between half-planes, tangent to a liquid surface and a solid-liquid interface at their intersection

Notes

NOTE In particular, the contact angle of liquid solder in contact with a solid metal surface. An approximate value for this can be determined by shadow projection or other means, by measuring after the solder has solidified. The contact angle is always the angle inside the liquid
