摘要： A lead-frame for semiconductor devices having a mold with at least one air vent for the resin to seep out of during its injecting into the mold, the air vent being positioned between the upper and lower surface of the frame, wherein the frame provides a through hole positioned at the outlet of the air vent so that, when the resin has solidified, it forms a flash which is in coherence with the surface of the frame.

摘要： A lead frame support plate 200 and a window clamp 400 for wire bonding machines are disclosed herein. In a described embodiment, the lead frame support plate 200 includes a network of suction grooves 218 provided on a support surface 212, each suction groove 218 being arranged to be in fluid communication with at least a vacuum hole 216 to enable a suction force to be created, in response to a vacuum force, along the network of suction grooves for holding a lead frame against the support surface. A window clamp 400 having slots for compensating deformation of the window clamp and a method of fabricating the lead frame support plate are also disclosed.
