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
