Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of semiconductor production, specifically relates to a mounting device for improving the attaching effect of radiating fin. BACKGROUND

[0002] With the increase of chip integration and power consumption, the heat per unit area of the chip is higher and higher when the chip works. Usually, radiating fins are attached outside the chip to make the heat generated by the packaged chip during work transmitted to the environment by the radiating fins.

[0003] To improve the heat dissipation performance of chip on film (COF) products, a radiating fin is usually attached to the surface of the product for heat dissipation. The radiating fin machine table first adsorbs the radiating fin through a marker head, moves above the position where the radiating fin needs to be attached, and then uses a roller to press, so as to fix the radiating fin on the product surface.

[0004] The radiating fin needs to completely cover the surface of the chip and ensure that the two are in contact to achieve better heat dissipation performance. The existing marker head is in a horizontal state when picking up and attaching the radiating fin, and it is not easy to expel bubbles during rolling, resulting in the accumulation of bubbles in the radiating fin. The marker head contacts the dry food product during the existing marker head attachment process, which can produce indentations on the surface of the dry food product, thereby causing the product to be scrapped.
