Procedure
Step 1 Hold the crimped connector with the front side facing you and check whether the metal

To ensure proper contact between the crimped parts and the core wires, the heights and
sizes of the metal contact strips must be uniform and standard.
The metal contact strips must be parallel to each other and offset by no more than 5°.
The top margin of a strip must be parallel to the axis of the connector and offset by no
more than 10°.
To ensure proper conduction, the surface of the metal contact strips must be clean.
The metal contact strips must be in sufficient with the RJ45 socket. The plastic septa
must remain intact and be aligned properly.
The soldering edge of a metal contact strip must surpass the ends of the core wires. The
ends of the core wires must be in contact with the edge of the RJ45 trough. The distance
between them must be less than 0.5 mm.
