Dear K.Suwit
Please consider about UPT mention and offer you to provide other way for prevent the problem :
1. Fast pass way to quickly get spare part ( how can we reduce lead time, less than 10 day after PO)
2. Spare part service from Nichepack (stock some importance part for UPT in Thailand)
3. Spare part shelf life , survey to check m/c
It’s better for us if we have new way to reduce probem , lead time in the future.

Phuwadon
