Turret terminals soldering, the preferred wrap conditions achieve a mechanical connection between the lead/wire and the terminal sufficient to assure that the lead/wire does not move during the soldering operation. Typically the mechanical connection includes a 180° mechanical wrap to effect mechanical connection.
1, Target - Class 1,2,3
• Wraps parallel to each other and to the base.
• Wire mounted against terminal base.
• On straight pins, the top wire on terminal is one wire diameter
below the top of the terminal.
• Wraps are a minimum of 180° and a maximum of 270°.
2, Acceptable - Class 1,2,3
• Wires and leads mechanically secure to terminals before soldering.
• Wires and leads wrapped a minimum of 180° and do not overlap.
3, Defect - Class 2
• Wrap has less than 90° contact between the wire and terminal.
4, Defect - Class 3
• Minimum wrap for round posts has less than 180° of contact between the wires and the terminal.
