Abstract
A roll has a structure in which a film is wound around a hollow core. The film is a dicing die bonding film having a surface where depressions and protrusions are formed. The roll is placed in a storage bag. Side plates are provided to both end portions of the roll being placed in the storage bag. Protruded portions of the side plates are attached by being inserted into both end portions of a follow portion of the core. With a pair of the side plates being attached to top and bottom ends of the roll, the side plates and the roll are secured with two to four bands. The bands are provided all around the outer portions of the side plates and the roll (storage bag) such that at least two bands cross, whereby the side plates and the roll are secured.
Claims6
A dicing die bonding film packing structure, comprising:
- a roll including a hollow core and a long dicing die bonding film which is wound around the core and pre-cut into a predetermined shape,
- side plates each having a protruded portion corresponding to a hollow portion of the core, and
- two to four bands for securing the roll and the side plates, wherein:
- the protruded portions are attached to be inserted into both ends of the core,
- at least two of the bands cross each other at a portion of the side plates, and
- an amount of change in a distance between a pair of the side plates disposed vertically at a time when the side plate on an upper side is lifted upward is equal to or lower than 1% of a distance between the side plates before the side plate on the upper side is lifted.
A dicing die bonding film packing method, comprising:
- winding a long dicing die bonding film having been pre-cut into a predetermined shape around a hollow core to form a roll;
- attaching to the roll a pair of side plates each having a protruded portion corresponding to a hollow portion of the core such that the protruded portions are inserted into both ends of the core;
- and
- securing the roll and the side plates with two to four bands such that the two to four bands cross at the side plates and an amount of change in a distance between a pair of the side plates disposed vertically at a time when the side plate on an upper side is lifted upward is equal to or lower than 1% of a distance between the side plates before the side plate on the upper side is lifted.
