    Tombstone...

    Well...maybe a partial tombstone. A real tombstone looks like it's ready for sex. That one is a bit pathetic.

    cold solder joint

    brittle solder joint is kindof related, kindof unrelated.

    but a cold solder joint also can be kindof partial, kindof brittle in the end.

    There can be many reasons including: wrong or old flux, wrong combination of metal alloys, wrong temperature, movement, wrong cooling, oxydized surfaces, solder not the right kind, just plain wrong manual handling
