Strain gauges for PCB testing are used for measuring various mechanical properties of PCBs in computers, instrumentation, digital products, household appliances, control devices, aviation quantitative assessment and identification. Use of these miniature strain gages helps to check and prevent various possible failure problems (such as BGA chip installation, circuit board installation stress, mechanical vibration, solder joint health monitoring, etc. ). These strain gages fully comply with IPC / JEDEC-9704 «Printed circuit board strain test guide» standard requirements.
