For low voltage Min Chen names:
- Too many types of terminals
- Angle of automatic clip assembly
- Limited digital visual detection technology
- Branch of harness lead to difficulties for automation
For high voltage two other challenges arose:
- Cutting aluminium foil by laser could burn the laser shielding layer
- The coaxiality of the silicone cables affects the quality of the stripping
And last but not least, the costs are an important factor too. High investments mean long pay-back periods.
