Strain Gage Analysis tips | 17 July, 2003

We have started an initiative to eliminate component damage within our SMT area in order to achieve <10ppm defect levels.

I would like to evaluate component stresses throughout the SMT assembly processes and wondered if anyone out there has experience of undertaking such an exercise.

Questions that arise are:

-What type of strain gages to use? -Where to position them? -What are the likely causes of component damage? -How to test a placement machine? -How to test other processes?

Can anyone advise me?

Cheers.

We doubt that stain gages will provide the granularity or repeatability to provide meaningful data.
