Title:
VENT MEMBER, METHOD FOR MANUFACTURING ELECTRONIC DEVICE INCLUDING VENT MEMBER, AND MEMBER SUPPLY TAPE
Document Type and Number:
WIPO Patent Application WO/2020/196211
Kind Code:
A1
Abstract:
The member of the present invention is a vent member arranged and used so as to cover a ventilation hole of a housing in order to allow gas to permeate between the outside and the inside of the housing via the ventilation hole and to prevent dust and/or liquid from entering from the outside to the inside via the ventilation hole. The member of the present invention has a porous film having air permeability in the thickness direction and a temporary protective film joined to the porous film so as to cover the porous film from the outside. The temporary protective film is not air-permeable in the thickness direction or has air permeability in the thickness direction lower than the air permeability of the porous film. The temporary protective film and the porous film are joined together in such a manner that the temporary protective film can be removed from the porous film. Even when the member of the present invention is reduced in size, adsorption failure is less likely to occur during adsorption with an absorption device, and damage to the porous film during adsorption can be suppressed.
