Testing Methods

AOI Testing
Checks for solder paste 
Checks for components down to 0201\" 
Checks for missing components, offset, incorrect parts, polarity

X-Ray Inspection
X-Ray provides high-resolution inspection of: 
BGAs 
Bare boards 

In-Circuit Testing
In-Circuit Testing is commonly used in conjunction with AOI minimizing functional defects caused by 

component problems. 
Power-up Test
Advanced Function Test
Flash Device Programming
Functional testing
