摘要:
The present invention relates to a cover tape and to an electronic component package that uses the cover tape, the cover tape comprising at least a substrate layer, a heat seal layer, and an antistatic layer, the antistatic layer containing (A) an ionic liquid including a cyclic quaternary nitrogen-containing cation, (B) a quaternary ammonium salt, and (C) a polyalkylene glycol being formed on a surface toward the heat seal layer, and an anion constituting the (A) ionic liquid including a cyclic quaternary nitrogen-containing cation and the (B) quaternary ammonium salt being one or more anions selected from the group consisting of carboxylic acids, sulfuric acid esters, phosphoric acid esters, sulfonic acids, and phosphoric acids.
摘要:
A cover tape having a temperature at which a heat shrinkage rate in at least one of a machine direction and a transverse direction perpendicular to the machine direction is 5% or more between 80°C to 200°C.
摘要:
A cover tape is provided for sufficiently suppressing corrosion of a metal part of an electronic component, even when the electronic component is stored in a high temperature and high moisture environment for a long period of time, and a carrier tape system for packing the electronic component is provided for stably obtaining a suitable peeling strength at the time of peeling the cover tape. The cover tape is provided with at least a base layer and a heat seal layer, and has; (1) an antistatic layer, which includes an antistatic agent and an antirust, and is formed on the surface of the heat seal layer, or (2) an average surface roughness (Ra) of 0.3-1.0μm on the seat seal layer side, and has an antistatic layer whereupon an antistatic agent is applied on the surface.
摘要:
An embossed carrier tape suitable for a high-speed mounting and a sheet for an embossed carrier tape. The tear strength conforming to JIS-K-7128-3 of the sheet is higher than 105 N/mm, thereby providing a sheet for an embossed carrier tape with superior high-speed mountability.
摘要:
A sheet excellent in antistatic properties, transparency and impact strength, and a formed product thereof. The sheet is made of a resin composition comprising an elastomeric styrene polymer and component (B) in a mass ratio of from 98/2 to 80/20, wherein the elastomeric styrene polymer comprises styrene monomer units, (meth)acrylate monomer units, etc., and component (B) comprises (B1) an amino carboxylic acid having at least 6 carbon atoms, a lactam, or a salt of a diamine with a carboxylic acid, having at least 6 carbon atoms, (B2) at least one diol compound and (B3) a polyether ester amide having a C?4-20#191 dicarboxylic acid copolymerized.
