Installing strain gauges is the most reliable method to measure loads, weight, torque, and mechanical stresses that have been long established and used throughout industries.

The aerospace industry being the pioneer of strain measurement techniques, has long benefited from the reliable data that a small and economically sound strain gauge can provide. This achievement has been used throughout industries and today remains the fundamental step toward the introduction of new products or investigating failures.

For the newly developed product or to perform failure analysis for the production products, measuring strain will provide the most accurate data only if the strain gauge has been installed correctly. while strain gauges measure a relatively small quantity in the range of   + 1 microstrain in material displacement, this measurement could be greatly affected by an error in installation or measurement techniques.

The installation of strain gauge requires meticulous attention to details such as the property of substrate material, temperature and environmental condition, the bonding method, and surface preparation of the material. In addition, the mechanical performance of adhesive, strain gauge matrix, and measurement technique can vastly influence the outcome of strain data.

Accuratio, through years of experience providing strain gauge installation and measurement for aerospace, oil and gas, automotive and other industries has gained an expert understanding of what requires to perform a proper strain measurement project.

we offer capabilities and expert service for all types of strain gauge installation including:

• High temperature and cryogenics application.
• Ceramic cement adhesive application.
• weldable strain gauges application.
• Fatigue and creep strain gauge application.
• static and dynamic application.
• composite and exotic material application.
• polymers and high elongation material application.

• residual strain measurement application.

in addition to on site installation of strain gauges (foil, free filament and semi conductor) Accuratio offers its expert service in installation of:

• Crack propagation and crack indicator gauges to measure and indicate crack.
• Thermocouples and RTD to measure temperature.
• LVDT and POTs to measure displacement.

All strain and crack gauges, thermocouples, LVDT's and other transducers installed by Accuratio will be thoroughly tested and confirmed both by our expert staff and clients to ensure all steps have been completed prior to starting a strain measurement project.

All strain gauges will be calibrated and balanced using state-of-the-art equipment and will be connected to a data acquisition system of the client's choice.

Accuratio will provide bridge completion for 1/4, 1/2  bridge circuitry, and temperature compensation bridges if required.

PCB Strain Gauge Installation Service

We provide PCB strain gauge installation and strain measurement service for all types of PCBs.

· Specialized in installation of micro miniature size strain gauges on PCB board per IPC/JEDEC guidelines

· Stacked rosette strain gauges or planner rosette strain gauge 0.76 mm (0.03" in) in length.

· Equipped with high speed data acquisition system to measure dynamics strain and strain rate.

· Live data interpolation and reduction for rosette strain gauges

· Expert in installing strain gauges for high temperature and cryogenic application.

Accuratio provides complete PCB strain gauge installation and strain measurement  to test printed circuit boards and assembly per IPC/JEDEC specification.

PCB strain measurement is used to determine the principal strains and strain rate levels to which surface mount components will be subjected during assembly, test and operation .

It's often required that PCB boards be tested for strain and mechanical loads during development. This will minimize the risk of cracks and failure of boards during production and transportation,.

Strain measurement is the only method that can reliably produce PCB performance data under mechanical loads.

Installing micro miniature sized rosette strain gauges on PCBs is a challenging task that takes many years to excel. A proper PCB strain measurement requires great attention to installation details and an experienced installer to avoid any probable installation error and consequent strain data error.  We  install stacked rosette gauges using optical microscope and micro sand blaster that are ESD safe. the installation is validated using strain gauge installation tool kit before testing starts. Accuratio will coat all installed gauges using proper coating material and techniques suited for the specific environmental condition.

By installing stacked rosette strain gauges or planner rosette strain gauges, strain measurements are taken from discrete points on the PCB .  Each rosette strain gauges consists of 3 strain gauges that measure strain gauges in 3 directions independently.  The strain measurement using rosette gauges will provide:

• Strain data at each grid (45º  or 60º apart)
• Maximum and Minimum principal strains
• principal angle
• Shear strain
• Diagonal Strain

using acquired strain data from the rosette strain gauge a complete stress analysis can be performed for the PCB board that will identify any area of concentrated stress. these data can be used to modify the board, fixture or production method to eliminate any cause and concern of board failure 

from the start of a typical strain measurement project we can help you to determine:

• Type of strain gauges that would best suit your project.
• Type of adhesive and installation that works for the temperature and material.
• Bridge completion and temperature compensation.
• Protective coating and wiring of strain gauges to obtain accurate measurement.
