Normally inspector is operating the verification station - such as checking the components found by AOI, feedback to the system about real defects and false calls, scanning barcode to find certain board, load data for the recipe and so on... Line ope

AOI should be operated by an INSPECTOR! Inspectors do not operate assembly machines or automated assembly equipment, why would an operator run an Automated Inspection? Are your operators certified to IPC standards to make calls on bad solder joints o

We have a board that has been diagnosed with inner layer separation from the barrel wall. This board is .093 thick and 12 layers. Several layers, in some cases, have little or no thermal relief making soldering difficult. We have since switched t

We're with your customer. We believe inner layer separation is not linked to a heating excursion. What you are seeing is separation between the hole wall and the copper plating in the barrel of the hole on an unstressed PTH. Although, it's possibl

I know plenty of 1980's CP3's & IP1's still out there, and the CP4's & 6's, IP2's & 3's are still going very strong after a decade or so & still commanding top dollar second hand. It depends on how well a machine is made & the type of engineering u

most pick and place machines will run for a very long time provided the operators keep them clean and well lubricated (10 years +). Often we end up replacing equipment not due to inoperability as much as due to capability. as packages and use chang

MKS, You do not need to reach a temp of 245C to form a joint and surely not for 0603s. Since you are using such a high temp your flux is getting dried out.. Also if you are going to reach a peak of 245C on a brd that has Sn/Pb compt and Pb-free.. yo

I agree with Grant, I posted a reply to your other thread as well so wont go into detail on machines but if quality matters, go with a tier one supplier. Even Fuji is dropping thier prices. We picked Universal, I cant believe the difference in pick r
