Description

Technical Field

[0001] The invention relates to the technical field of chip back-end packaging equipment, and in particular to a back-end packaging device for disc-shaped chips. Background Art

[0002] At present, after the integrated circuit chips are taped into a roll, they usually need to be wrapped with protective tape and the joints of the protective tape need to be sealed. After the disc-shaped chips are manually inspected and re-inspected, a fixed length of protective tape is manually taken, and after it is wrapped around the reel once, masking tape is pasted on the joints of the protective tape.

[0003] The protective tape can better protect the chip and prevent it from being damaged. In addition, the protective tape can also prevent the chip from being damaged during transportation. However, the original chip back-end packaging operation mode has the following disadvantages:

[0004] The winding of existing protective tapes and adhesive tapes is done manually, which has the problems of high labor intensity, low production efficiency, and high labor costs. In addition, if the protective tape or adhesive tape is forgotten during manual operation, the chip will be easily damaged. In addition, the tightness of the winding varies with manual operation. If it is too loose, the protective tape will spread out and will not play a protective role. If it is too tight, the chip in the tape will be crushed. At the same time, there are differences in the pasting position of the masking tape, which is poor in aesthetics.

[0005] There is also a Chinese invention patent with publication number CN102991773A, which provides a winding device for integrated circuit chip packaging. Although it can automatically wind the protective tape and sponge strip, it only discloses the use of equipment such as a gluing machine and a winding machine, but does not disclose the specific structure of the equipment, and has no practical reference value.
