A system for positioning a carrier relative to a travel path which includes a base having a pair of opposing side walls extending normal to the base and defining a path therebetween. A force applying device is disposed in one of the side walls and extends into the path for applying a force in the direction of the other side wall. A pair of rotatable eccentric members is secured to the other of the walls and extends into the path for selectively positioning a carrier between the eccentric members and the force applying device.

System for positioning a carrier relative to a travel path

A system for applying a rotary force to strips of varying widths. The system includes a plurality of adjacent tracks of progressively greater width, each of the tracks disposed at a height above all tracks of lesser width. A plurality of rotating members are provided, one rotating member extending into one of the tracks and extending to the surface of the associated track. An adjustable drive disc is adjusted to be disposed over a preselected one of the rotating members and is movable toward the rotating members to apply a rotary force to a strip disposed between the rotating member and the disc. Each of the tracks is defined by a pair of spaced apart surfaces with all of the rotating members being on a common rotating shaft.

System for applying a rotary force to strips of varying widths

A method of curing a die attach material for a semiconductor device which includes providing a carrier containing a plurality of stacked leadframe strips, each leadframe strip with a die attach material thereon. One leadframe strip is ejected from the carrier, travels into a chamber and is centered therein. The leadframe strip is then heated and the die attach material is cured selective to the leadframe strip using a tungsten-halogen lamp. Simultaneously volatile products of the cure are exhausted from the chamber. The leadframe strip is then returned to its original position in the carrier, the carrier is elevated so that a different leadframe strip is in position for ejection from the carrier and is ejected.

The invention is a lead frame (30) with tie bars (32-35) having reenforcing channels (44, 53, 64) extending at least a portion of the length of the tie bar. The lead frame (30) and channels (44, 53, 64) in the tie bars (32-35) may be formed either by stamping or by chemical etching. Each channel tie bar has at least two parts (51,52) forming a channel, the parts extending from each other at an angle less than 180.degree..
