AI Technical Summary

Technical Problem

In the high temperature and high humidity environment or poor temperature and humidity control, the expansion and contraction of the hole cavity after punching leads to material quality accidents, and the bonding and matching performance with the hot melt upper cover tape is poor, resulting in large fluctuations in peeling force and sudden changes in peeling force, affecting the normal use of electronic components.

Method used

The slurry combination with targeted chemical coniferous wood pulp and chemical broadleaf wood pulp as the main and recycled pulp as the auxiliary. Through the in-pulp application, molding, primary calendering, surface calendering and secondary calendering processes, the surface sizing agent with specific raw materials composition and proportion are used to optimize the bonding matching between the electronic paper carrier tape base paper and the hot melt upper cover tape.

Benefits of technology

It effectively solves the phenomenon of paper tape stratification after repeated winding in subsequent processing and downstream use of electronic paper tape base paper, improves the bonding strength between the layers of the base paper, optimizes the bonding matching with the hot melt upper cover tape, improves the peeling stability, reduces the fluctuation of peeling force, achieves accurate and stable control of the peeling force, and improves the performance of electronic paper tape base paper.

Abstract

The invention provides electronic paper carrier tape body paper and a surface sizing production method thereof, and relates to the field of carrier tape body paper. The surface sizing production method of the electronic paper carrier tape body paper comprises the following steps of slurry treatment, internal sizing, forming, primary press polish, surface sizing and secondary press polish. According to the electronic paper carrier tape body paper and the surface sizing production method thereof, the phenomenon that the electronic paper carrier tape body paper is prone to layering after being repeatedly wound for multiple times in subsequent processing and downstream use can be effectively solved, and the bonding strength between the layers of the body paper is effectively improved; the bonding matching property of the electronic paper carrier tape body paper and the hot-melting upper cover tape is optimized, and the possible galling or layering phenomenon in the process of stripping the hot-melting upper cover tape is avoided; the stripping stability is further improved, the stripping force fluctuation is reduced, the abrupt change of the stripping force is avoided, the accurate and stable control on the stripping force is realized, the range of the stripping force is effectively reduced, and the use performance of the electronic paper carrier tape body paper is further improved.
