Crimping isn't just pressure; it's a cold weld. A properly executed crimp extrudes the wire strands and terminal barrel into a solid mass with no voids. This is governed by IPC/WHMA-A-620.
Crimp Height Verification
Crimp height is the most critical non-destructive measurement. If it is too loose, pull force fails and resistance spikes. If it is too tight, the wire strands shear off.

Common Mistakes in Crimping Standards
- Assuming static theoretical values over empirical testing.
- Ignoring thermal derating curves in enclosed routing spaces.
- Applying generic global standards without cross-referencing European ISO 6722 limits.
Frequently Asked Questions
What is the primary standard for this?
Typically governed by IPC/WHMA-A-620 for manufacturing and ISO 6722 for the physical wire attributes.
How frequently should tools be calibrated?
At least every 50,000 cycles, or per shift for high-volume automated lines.
