Embodiment Construction

[0026] In order to make the purpose, features and advantages of the present invention more obvious and understandable, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0027] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical," "horizontal," "left," "right," "u...

Abstract

The invention discloses an easy-to-tear cover tape, comprising a wax layer, an antistatic layer, a base material layer and a heat-sealing layer sequentially arranged from top to bottom. On both sides of the bottom of the material layer, the top of the wax layer is provided with several pressing blocks, the pressing blocks are protruding, and the strength of the pressing blocks is greater than the maximum strength of the wax layer, the antistatic layer and the substrate layer , The two heat-sealing layers are respectively provided with extruding blocks facing each other, the extruding blocks are arranged obliquely, and the upper end thereof is closer to the center line of the base material layer. When tearing off the cover tape, you can press the pressing block first, so that the pressing area can sag. At this time, the air pressure between the cover tape and the carrier tape will increase, which can push the extrusion block, which is equivalent to giving the extrusion block an oblique upward movement. The force is on the inner edge of the heat-sealing layer, which weakens the connection force between the heat-sealing layer and the carrier tape. With the external pulling force, the cover tape can be quickly torn. The invention also discloses a preparation method using the above cover tape.

Description

technical field [0001] The invention relates to the technical field of electronic packaging, in particular to an easy-to-tear cover tape and a preparation method. Background technique [0002] In order to protect electronic components from contamination and damage during transportation, they are usually loaded into pockets of carrier tape and sealed on the surface of the carrier tape with cover tape to form a closed package. [0003] Cover tapes are divided into heat-sealed cover tapes and pressure-sensitive cover tapes, among which heat-sealed cover tapes are more widely used. The heat-sealing cover tape is mainly a heat-sealing layer arranged on both edges of the cover tape. By melting the heat-sealing layer, the heat-sealing cover tape can be covered and pasted on the carrier tape to realize the packaging of electronic components. Electronics are quickly removed by peeling off the cover tape. [0004] The existing cover tape is not easy to be torn, and when the cover ta...
