Dear All,

I'm just a budding engineer in EMS field.
Here we used to manufacture different classes of PCBA.

I would like to know about different process that need to be considered while manufacturing class 3 product.
If we are going for microscopic inspection then, need to know why it is required. If any one familiar with this , kindly advice
