[ Problem Point ]
Heatproof of the heat-shrinkable tubing and heatproof of the sheath of the electric wire were different, and the electric wire scorched.
[ ⇒Kaizen Point ]
The tube heated with the Halogen Point Heater.
Shrinkage went well because the temperature rise and the cooling time were
short, and the temperature limiting was easy.
Because it was point heating, the heat stress of the electric wire was
suppressed to the minimum.
