Miniature strain gage is advantageous in applications that benefit
from small size and higher resistance
MALVERN, Pa.--(BUSINESS WIRE)--
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.
