After terminal crimping, we need to inspect the conductor crimping area, to ensure the conductor brush is in the specified area. If the conductor brush extend too much, will affect the terminal mating; if the conductor brush extend not enough, the terminal easy to fall off from the wire. So we need to follow IPC-A-620 to inspect the conductor brush after crimping.
Acceptable - Class 1
Process Indicator - Class 2,3
• Conductor strands not protruding past but flush with the end of the conductor crimp area of the contact (Figure (1)).
Acceptable - Class 1,2,3
• Conductor strands flared out but not extending outside of the contact (Figure (2)).
• Conductor strands extend past the end of the crimp of insulated terminal.
Acceptable - Class 1
Defect - Class 2,3
• Any conductor strands extending outside of the contact (Figures 5-37, 5-38).
• The conductor strands extend into the mating area of the contact (Figures 5-39, 5-40).
Defect - Class 1,2,3
• Outer insulation of insulated terminal is damaged exposing metal (Figure 5-40).
