Peel Strength(After solder floated, P/S-S4)kgf/cm
Remark : product lot mentioned above shall be referred to as the Production Master Roll, which
is produced from a continuous surface treatment process and from the same electrodeposited
foil lot.
5.PACKING CONDITION
Copper foil roll or cut sheets shall be suitably wrapped in packaging sheet and vacuum packed to
prevent oxidation, and boxed in wooden box. It shall be marked in accordance to Mitsui Copper Foil
(M) Sdn. Bhd.'s standard packing labels.
6.QUALITY ASSURANCE TERM
The Quality Assurance Term shall be three (3) months from the arrival date with the condition
that the copper foil shall be tightly sealed and stored in the atmosphere with temperature of
25 O C and below and maximum relative humidity of 60 %.
7.ASSIGNMENT OF LOT NUMBER
One continuously treated roll at surface treatment process is defined as one lot.
Definition of Lot number
Example :0-01-0357-01
0: Production year, ie. 0 for 2010
01:Surface treatment machine number, ie. 01 for Treater #1
0357:Number of treated roll or master roll. This number started from
0001 on Jan 01st of every year and increase in sequence
01:Slit roll number from the master roll
8.IDENTIFICATION OF BOX NUMBER
It consists of an alpha-numeric character which is assigned based on the box code, the shipment year and running
numbers (in ascending order).
Definition of Box number
Example:ABC-0S-0001
ABC:Refers to abbreviation from End-user name.
0:Indicates last digit of the year, i.e. 0 for 2010
S:Indicates the foil size and thickness.
0001:Indicates box sequence number in ascending order.
9.MISCELLANEOUS
Any revision and amendment made of the above requirement shall be with mutual agreement
between both party or authorized party, and made through writing.
