Second optical mouse support lead foot of foot, both sides is respectively equipped with several the first central tap feet for extending to PAD region and
Two central tap feet, several first central tap feet and the second central tap foot are connected to chip by die bond bonding wire respectively, if
Dry first central tap foot is detached with PAD region, and the second central tap foot is connect with PAD region.
Specifically, the optical mouse holder terminal body is made of plastic material.
Specifically, the optical mouse holder terminal body is rectangular platy structure.
Specifically, the second optical mouse support lead foot of side is flatly to the centre of optical mouse holder terminal body
Position is extended with third optical mouse support lead foot.
Specifically, the second optical mouse support lead foot of both sides extends outward optical mouse holder terminal body respectively
Outside.
Specifically, the both ends of the PAD region, which each extend over, is connected to third optical mouse support lead foot and the first light
Electric mouse support terminal pin.
