A heat spreader frame is provided including: heat spreaders having upper surfaces; a peripheral frame surrounding the heat spreaders; spreaders, the peripheral frame having stand-off legs; tie bars having upper surfaces and a pin identifier at an end portion of the tie bars, the heat spreaders connected to one another and to the peripheral frame by the tie bars, the width of the stand-off legs wider than widths of the tie bars; at least portions of the upper surfaces of the tie bars being thinned to reduce heights of the tie bars; the upper surfaces of the heat spreader in an elevated position supported by the peripheral frame; and the heat spreaders and the tie bars covered by an package molding compound exposing the upper surface of the heat spreaders and one surface of the pin identifier coplanar to the upper surfaces of the heat spreaders.

Leadframe-based mold array package heat spreader and fabrication method therefor

A method for fabricating a heat spreader is provided. Heat spreaders are formed and surrounded by a frame. The heat spreaders and frame are connected to one another by tie bars, the heat spreaders and tie bars having respective upper surfaces. At least portions of the upper surfaces of the tie bars are thinned to reduce the heights of the tie bars at least on a singulation line thereon. The frame is formed to support the heat spreader upper surfaces in an elevated position with respect thereto.

A method for forming a heat spreader, and the heat spreader formed thereby, are disclosed. An array heat spreader having a plurality of connected heat spreader panels is formed. Slots are formed in opposing sides of the heat spreader panels. Legs are formed on and extending downwardly from each of the heat spreader panels in at least an opposing pair of the slots on the heat spreader panels. The legs are integral with the respective heat spreader panels from which they depend.

Array-molded package heat spreader and fabrication method therefor

A method of manufacturing a pre-molded leadframe for use in a semiconductor package includes providing a leadframe having a die pad and a plurality of leads. A first molding material is formed in the leadframe to expose the upper surface of the die pad and the upper surfaces of the plurality of leads.

Pre-molded leadframe and method therefor

An optoelectronic sensor is attached to an optically transparent substrate, such as glass, and encapsulated to form an optoelectronic device. An optical assembly can be mounted opposite the optoelectronic sensor. Filters and refractive index matching materials may be included between the optoelectronic sensor and the optically transparent substrate.
