Crinkling
When the solder mask is applied to the circuit board after the tinning, it may happen that the heat is not dissipated and individual points overheat so that the tin layer melts under the mask, distorting the solder resist and forming wrinkles known as "orange peel". The reason for this phenomenon is the ratio of the internal tension of the solder mask and the cohesive strength of the solder. |
