 Micro Model Board Comparison
Model Board
ComparisonTM
(MBC) can identify defects on devices by
comparing their thermal behavior to a model. Models are created by
testing one or more known good devices.
MBC can detect
very small temperature differences between functional and defective devices
that are nearly impossible to detect using any other temperature measurement
method. During an MBC test, a sequence of thermal images is captured
while the device is energized. devices are energized by powering them or
by running a functional or diagnostic test. The I/O module provides
relay outputs and digital inputs that are used to control power to the
device.
Model Board Comparison
Settings
Models are
created by adding tests of known good devices to a group. Acceptance
Criteria determines how the device is compared to the model. Board
tests can be automatically saved to hard disk after each test.
Set the test
length and the rate at which images are evaluated during a Model Board
Comparison test.
Set the time
that each relay will be activated during the test. Only one relay is
needed when powering a device. Multiple relays can be used to perform
more sophisticated tests such as powering different device circuits or applying
different loads at different times. Relays 6 and 7 and the digital
inputs are used to synchronize tests with external test equipment.
