BorgWarner were interested to quantify the stresses applied on PCBAs for an HV Air Heater during an assembly process and whether the stresses applied were within acceptable limits.
IMaR obtained sample printed circuit boards from BorgWarner, sourced suitable uniaxial strain gauges, configured instrumentation and adhered the strain gauges to specified positions on each board. Strain measurements were undertaken in-situ, during the assembly process. IMaR analysed the data and reported the findings, detailing the maximum strain, maximum rate of change of strain and to what extent high strain coincided with high rate of change of strain. IMaR also supplied the raw data to the client.
