Another important of connector quality is crimp quality.

 
Comprehensive crimping can be inspected by micrograph .  Crimp height, a criterion to determine the crimping quality of terminals as following picture. 
 
A good crimp quality is to  meet the performance specifications related to crimp force, height and width; pull-out force; strip length; and insulation area. 
 
We use microscope to inspect the quality of crimped terminal cross-section. The crimp barrel must also show a slight deformation on its inner surfaces and exhibit no gaps.
