Hi Victor- IPC allows thick film resistors to be placed up-side down: the resistive material has an insulator over it. AND you can buy resistors which have no wrap on the ends and so must be placed this way. These parts are used in situations where the little "stubs" of the wraps might degrade signal quality (extremely high speed/high frequency stuff).
