Detailed Description
The invention is further described with reference to the following figures and embodiments:
As shown in fig. 1-2, an SMT adhesive tape for receiving materials comprises a release base film 1 and a working adhesive film 2, wherein the working adhesive film 2 is uniformly arranged on the release base film 1, a positioning sensing opening 3 is formed in the release base film 1, and the positioning sensing opening 3 is arranged in front of the working adhesive film 2; the working adhesive film 2 is a three-piece adhesive film, which includes a first adhesive film 21, a second adhesive film 22 and a third adhesive film 23.
Preferably, in a specific embodiment, the widths of the first adhesive film 21, the second adhesive film 22 and the third adhesive film 23 are all 18.6mm, the length of the first working adhesive film 21 is 36mm, the length of the second adhesive film 22 is 46mm, the length of the third adhesive film 23 is 25mm, and in addition, the arched concave portions 231 are uniformly arranged on the 25mm length of the third adhesive film 23, and the arched concave portions 231 are adjacent to the second adhesive film 22, that is, the arched concave portions 231 face the tape unwinding discharging direction. The arch concave 231 is designed mainly to avoid a transmission hole of the SMT material belt, and in addition, when the adhesive tape is subjected to die cutting, the gap between the arch concave 231 and the second adhesive film can conveniently discharge waste materials, so that the production quality and efficiency of the adhesive tape can be improved.
