Wire prepare is important for wire harness manufacturing, it's the first step to make the preparation.IPC-A-620 defind the wire conductor deformation and separation spec in 3.2/3.3 section. Below is the spec for reference.
Target – Class 1,2,3
• Strands are not flattened, untwisted, buckled, kinked or otherwise
deformed.
Acceptable - Class 1,2,3
• Wire strands disturbed during insulation removal have been
restored to approximate their original lay.
3.3 Wire Separation (Birdcaging)
Target - Class 1,2,3
• No birdcaging.
Acceptable - Class 1,2,3
• Wire strands have separation (birdcaging) but do not exceed
the lesser of:
• One strand diameter or
• Do not extend beyond wire insulation outside diameter.
