INTRODUCTION
Based on VFR’s Bulk Metal Z-Foil technology, the VFCP
Series (foil resistor flip-chip) excels over all previous
stability standards for precision resistors with an order
of magnitude improvement in high-temperature stability,
load-life stability, and moisture resistance. These new
benchmark levels of performance provide design
engineers with the tools to build circuits not previously
achievable while reducing costs and space in the most
critical applications by eliminating the need for corrective
circuitry and reducing the large land patterns needed
for a wrap-around configuration. The device’s flip-chip
configuration saves up to 35% PCB space compared with
a surface-mount chip with wraparound terminations while
also providing better strain relief to eliminate cracked
substrates and board delamination.
In addition to its remarkably improved load-life stability,
the VFCP Series is noise-free and provides ESD
protection of 25 kV or more for increased reliability. The
device’s solid element alloy is matched to the substrate,
forming a single entity with balanced resistance versus
temperature characteristics for an unusually low and
predictable TCR over a wide temperature range from
–55°C to more than +125°C. The adhesive that holds the
foil to the flat substrate withstands high temperatures,
pulsing power, moisture incursions, shock and vibration,
and low-temperature exposure while still holding securely
to the foil element. Resistance patterns are photo-etched
into the element to permit the trimming of resistance
values to very tight tolerances as low as 0.01%.
The Flip Chips devices are qualified as anti-sulfurated
resistors for use in environments with high levels of
contamination. Such environments include alternative
energy applications, industrial control systems,
sensors, RTDs, electric instrumentation, weather and
communication base stations, and any electronic
appliance used in high concentrations of sulfur. The
combination of flip-chip terminations and Z-Foil
construction and materials results in the most stable
resistors available, requiring the lowest error allowance.
This means that more error allowance can be transferred
to active devices—resulting in lower costs—or applied
to the foil resistors themselves, allowing for looser initial
tolerances than would be required for other resistor
technologies.

Note
To acquire a precision resistance value, the Bulk Metal Foil
chip is trimmed by selectively removing built-in “shorting bars.”
To increase the resistance in known increments, marked
areas are cut, producing progressively smaller increases in
resistance. This method reduces the effect of “hot spots” and
improves the long-term stability of VFR resistors.

HARMONIC DISTORTION
Harmonic distortion is an important consideration in the
choice of precision resistors for sensitive applications. A
significant signal voltage across the resistor may change
the resistance value depending on the construction,
material, and size. Under these conditions Bulk Metal Foil
resistors behave more linearly than other resistor types.
FLOWER OF SULFUR
ASTM B 809, also known as flower of sulfur, is a test to
determine the porosity of metallic coating using humid
sulfur vapor. This vapor can penetrate conformal coatings
and cause damage to the device when it reacts with
lower layers of silver. Surface-mount Bulk Metal Foil chip
resistors avoid this problem with a special coating that
is proven to be reliable in extreme environments and
even against sulfur. The flower of sulfur test is especially
