POST MANUFACTURE OPERATIONS (PMO)
What is the importance of resistor stability in an electronic circuit?
Answer: The circuit was probably not intended for just a onetime
use. Also, the equipment may have to endure some environmental
and operational stresses. So, the ongoing use of the equipment is
expected and the more stable the resistors, the longer the time
before recalibrations. FRSM offers the most stability in all categories
but there is more than recalibration at stake here: extremes of surge
voltage can cause thin film resistors to go open while the Foil resistor
based on the Z-1 technology is not affected. An open means the
equipment must be returned to the maintenance department to have
the resistor replaced or, worse yet, mission failure. The cost of a Foil
resistor would have been insignificant compared to the cost of
mission failure or the cost of returning an instrument for repair or
replacement of a blown resistor. Add to this the down time of the
equipment.
the end of that period, and in spite of permissible service conditions,
the equipment is expected to still be functional in its intended service
and within its accuracy limits. All the components contribute in some
way to the stability of the equipment but the resistors are the devices
relied upon most to retain the original accuracy of the equipment.
Any departure from the end-of-life accuracy limits set for one resistor
renders the entire equipment “out of service” and subject to repair or
recalibration. The prospect of repair or recalibration is unthinkable in
certain applications (space for example) and only devices that can
be given an appropriate initial tolerance with the expectation of
retaining proximity to the initial value throughout the service life are
suitable. This is especially true of the resistors in a circuit which may
have power applied causing self heating, load applied for extended
periods or load life and load applied differentially from other resistors
resulting in a ratio offset. The equipment itself may see elevated
temperatures for extended periods of storage. Foil resistors are the
best solution when these factors come into play.
Designing for extended service - All electronic equipment is
expected to do something useful for a specified period of time. At
