This photo shows a fairly even, but not perfect, crimp taking place.
What we are really looking at here is a run-of-the-mill quality three piece terminal. While it is a three-piece terminal, this one does not feature a brazed seam and we can see that even with a fairly even crimp the seam is beginning to open. Brazed seam insulated terminals, like the AMP PIDG terminals, cost more but are a better quality terminals.
