Definitions
- the present invention relates to a desiccant container and an adhesive tape reel.
- anisotropic conductive tape is known as an adhesive tape used for connecting members to be connected having a large number of electrodes and fixing a lead frame.
- anisotropic conductive tape for example, when connecting a semiconductor element such as an IC or LSI to a substrate such as a printed wiring board, a glass substrate for LCD, or a flexible printed board, the opposing electrodes are made conductive while the adjacent electrodes are connected to each other. The insulation state can be maintained.
- an adhesive layer containing an adhesive component containing a thermosetting resin and conductive particles blended as necessary is formed on a substrate such as a polyethylene terephthalate film (PET).
- PET polyethylene terephthalate film
