Abstract

The invention discloses a semiconductor package transfer mechanism and a semiconductor package transfer method. The semiconductor package transfer mechanism includes a plurality of pickup units, which are movable along a shaft extending in one direction and operated individually from each other, and a vision inspection apparatus installed across a moving route of the pickup unit in order to inspect defects of the semiconductor packages transferred thereto by means of the pickup units. The pickup units pick up a predetermined amount of semiconductor packages adapted for one-time photographing capacity of the vision inspection apparatus and instantly transfer the semiconductor packages to the vision inspection apparatus. Time delay and waiting time for the semiconductor packages are significantly reduced during the process of the handler system, thereby significantly improving the transfer efficiency and vision inspection efficiency.

Description

technical field [0001] The present invention relates to a transmission mechanism and a transmission method for semiconductor packages, in particular to a semiconductor package that is picked up by a pick-up unit and adapted to the one-shot capacity of a video detection device, and immediately delivered to the video detection device The delivery mechanism and delivery method of the prepack. Background technique [0002] Generally, to make a semiconductor package, a semiconductor chip having highly integrated circuits such as transistors and capacitors is attached to a semiconductor substrate made of silicon, and the upper surface of the semiconductor substrate is molded with resin. After the molding process, a ball grid array (BGA) as a lead frame is adhered to the lower surface of the semiconductor substrate so that the BGA is electrically connected to the semiconductor chip. Afterwards, the sawing process of the semiconductor substrate is completed by a sawing machine, so ...
