Well understood supplier must produce spec according to our requirement ,, I have emphasized to them .
However , they would like to hit our target spec but it seem difficult to make it happen when he run for sample roll ( weight and elongation are A BIT out of spec ) , that’s why he has such below questions to get more understanding our product and adjust to the next sample roll .
Purchasing tries utmost to get the better thing , due to our current supplier Xinyu has no comfortable to accept our MRR and sign does not good , that’s why we need to find alternative source if any unexpected problem happen in future .
Anyway , noted your comment and thanks for your support .
