What's the IPC spec of Discrete Wire Termination – End Connectors?
Below is the IPC spec for such IDC connection.
Target - Class 1,2,3
• Wire fully seated into the contact.
• Wire extends at least 50% of the distance between the contact edge and the back wall of the connector.
Acceptable - Class 1,2,3
• Wire touches back wall with slight deformation but the top of the wire does not rise above the back wall.
• Portions of bare conductor are visible but no bare conductor extends outside the connector body.
• Exposed conductors do not violate minimum design electrical clearance.
Defect - Class 1,2,3
• Wire stripped or partially stripped before being inserted into the connector.
• Wire not within retaining barbs.
• Two wires into a single contact unless the contact or connector specifications indicate that this is acceptable.
• Deformation of the connector body due to wires with oversize insulation.
• Insufficient stress relief on wires entering connector.
• Wire size does not meet connector parameters.
• Wire not fully seated in both sets of v-notches of the IDC contact.
• The wire extends less than one wire diameter out of the rear contact.
• Broken retaining barbs on the connector.
