Preparation method of high-stability electron carrier tape base paper with square holes at high temperature and high humidity

Abstract

The invention discloses a preparation method of high-stability electronic carrier tape body paper with square holes at high temperature and high humidity, and relates to the technical field of carrier tape body paper preparation processes. Defibering, pulping and mixing the pulp; the method comprises the following steps: defibering and pulping bleached softwood commercial pulp and bleached hardwood commercial pulp respectively, and then mixing together to form mixed pulp; s2; sizing in the mixed slurry, molding and drying; carrying out papermaking on the mixed pulp through a three-layer rotary screen paper machine, and spraying starch between layers for compounding; (S3); sizing and calendaring the surface of the dried paper sample; the paper sample is subjected to infiltration and film transfer sizing, and then the paper sample is subjected to super calendering to prepare the electronic carrier tape body paper. The problems that in the prior art, punching forming operation needs to be carried out on a carrier tape before braiding, the size of a hole after punching is changed due to water absorption of carrier tape paper, and consequently electronic components stand laterally or are clamped in the packaging process are solved.
