Abstract:
A method of forming microelectronic packages of the type including a microelectronic device, a receptacle formed of an insulative material and defining a cavity for receipt of the microelectronic device, and a leadframe formed of a conductive material and facilitating electrical connection of the microelectronic device to an external circuit, characterized in that the packages are formed in a continuous process comprising:moving a continuous strip of an electrically conductive substrate material along a feed path; at a removal station along the feed path, the step of removing material from the continuous strip to define a series of successive connected leadframes from the remaining material with each leadframe including a series of leads; and at a forming station along the feed path, spaced downstream from the removal station, the step of forming a receptacle of electrically insulative material on the substrate strip at a respective leadframe, with each receptacle defining a cavity for receipt of a microelectronic device and with each receptacle formed integral with the respective leadframe, such that the leads of the leadframe extend from the cavity to the exterior of the receptacle to facilitate electrical connection of the microelectronic device to an external circuit; and at an attachment station, the step of placing a microelectronic device in the receptacle.
