Abstract

The invention provides a cover tape and the method for manufacturing the same. The cover tape comprises an antistatic layer, two intermediate layers, a base layer, two tie layers and a heat seal layer. These seven layers are formed by a co-extrusion process. The cover tape has a double-side antistatic characteristic of the heat seal layer and the antistatic layer and a characteristic of synchronous co-extrusion forming of layers, and has the advantages of simplifying manufacturing process steps and the like.

Description

technical field [0001] The invention relates to a covering tape and its manufacturing process, in particular to a covering tape formed by one-time extrusion of multi-layer materials and its manufacturing process. Background technique [0002] Electronic components such as integrated circuit chips are generally stored in carrier tape before being assembled on a printed circuit board. The carrier tape has a plurality of storage pockets or storage slots for accommodating electronic components, and the electronic components are packaged in the carrier tape in a heat-sealed manner by a cover tape. When assembling, the cover tape is peeled off first, and then the electronic components are taken out one by one by automatic equipment such as a robot arm along the direction of the carrier tape and placed on the printed circuit board. [0003] Generally, the cover tape must have sufficient light transmittance to facilitate observation and identification of electronic components in th...
