Abstract:
A sucker for catching and transferring packaged semiconductor devices, comprising:a position rod (10) having an air extraction channel (11) formed axially therethrough;an elastic buffer pad (20) having an aperture (21) formed in an upper surface thereof for coupling with an end of said position rod (10), said elastic buffer pad having a first air hole (22) formed in a lower surface thereof and in open communication with said aperture (21) and said air extraction channel (11); anda sponge (30) attached to said lower surface of said elastic buffer pad (20), said sponge (30) having a single second air hole (31) formed therethrough in open communication with said first air hole (22), said sponge (30) being sufficiently soft and elastic to conform to a packaged semiconductor's contours and thereby provide a vacuum seal when air is extracted from said air extraction channel (11).
