Hi Anyone aware of any AOI machine that capable of inspection underfill fillet before curing. regards

I must have been confused on the email chain when I originally bought the machine back in 2020. Stephen Nigro told me it would be 12.9k + travel expenses. Do the manuals include service manuals/exploded views for ordering parts?
