Tin in solder or some other meals can form spiky crystals when under stress. These whiskers can form short circuits if not properly insulated or not alloyed with other metals.

Tin whiskers usually don’t occur with most solders, are solders are formulated to prevent them. Perhaps this is defective solder, or there was a high thermal gradient, or repeated heat cycling has fractionated the alloy?
