PCB testing methods during manufacturing and assembly?

We plan to visit factory next week. Could we know more about how many basic PCB testings in EMS field?
  1. VISUAL INSPECTION
  2. IN-CIRCUIT TESTING (ICT)
  3. FLYING PROBE TESTING（FPT）
  4. AUTOMATED OPTICAL INSPECTION (AOI)
  5. AUTOMATED X-RAY INSPECTION（AXI）
  6. FUNCTIONAL TESTING (FCT)
  7. BURN-IN TESTING

What Others Are Asking

How can I determine BGA land pad diameter for given ball diameter?

I’m working on a project which requires the use of a CSP package. The product’s datasheet provides ball pitch and ball diameter but nothing about the preferred land pad diameter.
How can the pad diameter be worked out from these figures assuming an NSMD land?
