Utility Tests simplified by the interaction of the measurement system with various environmental test chambers. Interaction with the environmental test chamber The AMR can be connected to three environmental test chambers for testing. Interaction with the environmental test cha mber enables temper at u re a nd humidity monitoring, management of the time schedule, and it displays an alarm when a failure is detected. Real-time monitoring of temperature and humidity AMR monitors and records the temp. and humid. inside the environmental t e s t c h a m b e r. D a t a a r e r e c o r d e d...

Evaluation DC or AC measurement can be selected according to your test requirements. Example: reliability evaluation of BGA and CSP solder ball connections (Daisy chain evaluation) DC and AC application evaluation Case in which signals between measured channels do not interfere with each other (communication between channels is independent from each other IC chip Using AC micro current to measure small voltage changes without being affected by thermal electromotive force. It is suitable for the obser vation of ch a nge s i n c ond uc t ive r e sist a nc e evaluations. DC application only...

Evaluation Two failure recognition methods can be performed to detect the failure in conductive resistance of the joint parts. Failure recognition using the absolute value The date obtained at measurement intervals are evaluated using the preset absolute value. It will detect small changes of conductive resistance due to micro-cracks, and will do so until total opening of the crack. Ab s olu t e v a lu e c a n b e s e t i n h ot condition and cold condition to have separate identif ications f rom both t empe r at u re e nd s.
