Note:Customer can adjust the technology based on the real condition when processing.
(1)Peel off protection layer first, and then bond to FPC, 80℃Heating table can be used for pre bonding.
(2)Laminate in accordance with the above process, take out, and then peel off the carrier film after cooling.
(3)Solidification process.
Packing
（1） Standard Specification of product: 250mm×100m.
（2）After removing static electricity, the products are packed in aluminum foil paper and also put drier in it.
（3） Outside is packed in paper cartons and fixed to ensure the safety of products during transportation and handling, and avoid damage.
Storage and Attention
（1）Recommended Storage Condition
Temperature: (0-10)℃; Humidity: below 70%RH
（2）Attention
（2.1）Please do not open the outside package and balance the shielding film at room temperature for 6 hours before using to reduce the effect of frost and dew on the shielding film.
（2.2）Suggest to be used as soon as possible after take out from the cold storage, in case of quality changing under the normal temperature for long time .
