Switching to the 3mm LED diode with 53mm long pins delivered key improvements:
-
Eliminated the need for custom wiring extensions
-
Reduced assembly time by 35%
-
Achieved perfect LED alignment through all housing layers
-
Improved reliability due to fewer solder joints
The redesign significantly streamlined their production workflow and reduced long-term maintenance issues.
