Abstract

The invention discloses paper for packaging a carrier tape and a preparation method thereof. The paper and the preparation method are characterized in that the thickness of the paper for packaging the carrier tape is 0.25mm-1.00mm, the thickness deviation is plus or minus 0.02mm, the compactness is 0.80-0.95g/cm<3>, the moisture content is 6.0%-9.0%, the deflection is greater than or equal to 30mN.m, the peel strength between all the layers is greater than or equal to 80ftlb/1,000in2, the critical wax rod strength of a surface layer is greater than or equal to 18A, and the residual rate of burrs (soft flocks) greater than 0.1mm in a carrying hole punched by using a punching mould is less than 5/1000. According to the paper for packaging the carrier tape and the preparation method thereof, by utilizing short fiber paper pulp subjected to pulp grinding treatment, and adding and spraying a high-molecular polymer resin adhesive, dry-strength resin, wet-strength resin, a stiffening agent, a sizing agent and the like into the paper pulp and between made wet paper sheet layers, a three-dimensional network structure is formed by bonding paper pulp fibers with various polymer resin macromolecules, so that paper boards have relatively high interlayer bonding strength, surface strength and stiffness, and the fibers are easier to cut off during punching to reduce the production of the soft flocks, so as to meet the quality requirements for the packaging the carrier tape.

Description

technical field [0001] The invention belongs to the technical field of electronic information materials, and in particular relates to a tape carrier packaging paper used for packaging chip electronic components in the field of microelectronics and a preparation method thereof. Background technique [0002] With the development of miniaturization of electrical appliances, the requirements for the miniaturization of electronic components are getting higher and higher. Chip electronic components are the mainstream form of discrete electronic components, and their size is getting smaller and smaller. From 3216 to 1608, its application The mainstream size is transitioning from 1608 to 1005. At present, the smallest has developed to 0603 or even 0402. At such a small scale, the packaging, transportation and access of components must have corresponding carriers. Plastic carrier tape is used as a packaging carrier, but it is acceptable to use plastic carrier tape when the size is la...
