Miniature strain gage is advantageous in
applications that benefit from small size and higher resistance
The Micro-Measurements® brand of Vishay Precision Group, Inc.
(NYSE: VPG) (www.micro-measurements.com), industry experts in the
design, development, and manufacture of resistive-foil sensors for
high-precision strain, high-stress and force mechanism
measurements, today introduced the G1350 C2K-Series strain gage, a
miniature stacked rectangular rosette sensor built to meet the
developing need for precise, consistent, and reliable stress
analysis of PCBs, even in severe environments. The G1350 is
designed to detect PCB surface strains at critical locations in
consumer electronics. The miniature strain gage is particularly
advantageous in applications that can benefit from its small size
and higher resistance of 120 ohms and 350 ohms.

The G1350 is ideal for applications in Structural Health
Monitoring (SHM), Industrial Internet of Things (IIoT), autonomous
vehicles, instrumentation & control, machinery & equipment,
motion control, Industry 4.0, robotics, smart cities, smart
manufacturing, smart infrastructure, wearable electronics, and
wireless applications.
Designed using the same rigorous standards as traditional
Micro-Measurements gages, the new line of C2K series strain gages
is based upon advanced technology manufacturing processes that
allows high resistance in small-sized gage patterns. The uniaxial
linear stacked rosette C2K-06-G1350-350 features an active grid
length of just 0.040” and an overall matrix of 0.20”diameter to
allow spot-on installation on surface-mount components. The 3
meters of pre-attached three-conductor cable is built to ease and
speed-up installation processes by eliminating the need of lead
wire soldering after bonding.
Miniaturizing consumer electronics will result in higher
component density, increased thermal stresses, new requirements for
surviving repeated loadings, and a larger need for impact stress
survival. In order to meet these requirements, precise knowledge of
strains in the PCB and on-board components is a must. The most
accurate, swift, and cost-effective manner to detect strains on a
PCB is through strain gage measurement, which can also be used in
developing loading fixtures and test plans to optimize the testing
phase.
The new strain gage features a Modified Karma, or K-alloy (C2K),
and an epoxy overcoat for grid encapsulation. The second generation
of the G1350 is based on K-alloy, with its extensive areas of
application, representing a vital member in the family of strain
gage alloys for PCB testing. Categorized by strong fatigue life and
excellent stability, K-alloy strain gages can be exposed to
temperatures as high as +150°F (+66°C). An inert atmosphere will
strengthen stability and extend the useful gage life at high
temperatures. Among its other advantages, K-alloy offers a much
flatter thermal output curve than A-alloy, allowing more precise
correction for thermal output inaccuracies at temperature extremes.
Like constantan, K-alloy can be self-temperature-compensated for
use on materials with different thermal expansion coefficients.
K-alloy is the normal selection when a temperature compensated gage
is required that has environmental capabilities and performance
characteristics not attainable in A-alloy gages.
As required by standards in the electronics industry, PCAs must
be tested to determine if the design can withstand the rigor of
manufacturing, packaging, transporting, and day-to-day use of
electronic devices. Some of the methods in the process in which
strain gages are used for printed circuit assembly testing include:
ensuring appropriate surface preparation materials are on hand,
selecting an adhesive, selecting a protective coating that will
resist environmental conditions, and selecting the measurement
instrumentation.
