Technical Field

[0001] The utility model relates to the technical field of semiconductors, and particularly relates to a dust sticking fixture for a protective tape. Background Art

[0002] In recent years, chip packaging mostly adopts the tape automated bonding technology. Before packaging, it is usually necessary to cover a protective tape on the tape first to isolate the direct contact between two adjacent tapes wound on the reel. During use, particles will be generated due to the adhesion and friction between the protective tape and the tape. Since the protective tape is recycled repeatedly, it is necessary to clean the particles on the protective tape in time. Most of the existing cleaning methods are to place a dust sticking pad on the particle receiving plate, and the staff manually makes the protective tape contact with the dust sticking pad to stick and remove the particles. However, in the actual operation process, the protective tape is very easy to adhere to the dust sticking pad and lift it up, affecting the work efficiency. Content of the Utility Model

[0020] As Figures 1-5 shown, a dust-removing jig for a protective tape includes a receiving plate body 1, a dust-removing pad 2, and a separator plate 3. Through holes 11 are formed at the top ends on both sides of the receiving plate body 1 in a matching manner. The dust-removing pad 2 is located at the top of the receiving plate body 1, and the separator plate 3 is arranged above the dust-removing pad 2. The separator plate 3 is made of acrylic material, and a plurality of through holes 31 are formed in the separator plate 3. The diameter of the through holes 31 is 20 mm, and the distance between adjacent through holes 31 is 10 mm. At the same time, silicone pads 33 are provided at the four corners and the middle position of the bottom of the separator plate 3. When in use, the staff passes the protective tape through the through hole 11 on one side into the top of the receiving plate body 1, places it on the separator plate 3, and then passes it out through the through hole 11 on the other side. During the pulling process, the protective tape contacts the dust-removing pad 2 through the through holes 31 on the separator plate 3, so as to remove the particles on the protective tape.
