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.

Rosette PCB Strain Gauges

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

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
