Why Won T My Solder Stick To Circuit Board. Make sure the tip of the iron is nice and shiny. Circuit board wont desolder.

It happens when the iron gets a coating of crap on it so the solder cant directly contact the metal. Sometimes a solder Bridge will occur joining two pads together. If solder doesnt stick well during soldering that is usually a sign of lack of flux or the parts being soldered being either too cold during soldering or dirty not clean bare metal during.
Touch some solder on it and it should melt almost instantly.
The proper amount of heat must be applied to both the foil a. Melted soldering parts will destroy sensitive welds and links on a circuit board that could house important fans or critical CPUs. Overloading causing tensile rupture fracture long-lasting permanent loading creep cyclic loading fatigue. Failed Solder Connections.
