The cause of cold solder after a drop test => Cold solder prior to properly performing a well designed drop test.

Actually, "cold solder" means different things to different people. Two dull solder connection conditions are: * "Disturbed" solder joint: a solder joint that has an "angular faceted" appearance that is caused by the solder joint being moved as it solidified. * "Grainy" solder joint: a solder joint that has a rough, gritty appearance that is caused by the solder microstructure giving the solder joint surface relief.
