用于引线框识别的中间层
Abstract:
本发明提供一种制造集成电路IC装置的方法，所述方法包括提供引线框薄片堆叠，每一引线框薄片包括多个引线框和一个插入在所述引线框薄片的邻近引线框薄片之间的中间层部件(101)。所述中间层部件包括识别所述引线框薄片的标记(101)。将所述引线框薄片堆叠装载到装配机器上(102)。从第一引线框薄片移除第一中间层部件(103)。将所述第一引线框薄片转移到所述装配机器的安装表面(104)。将半导体裸片附接到所述第一引线框薄片上的引线框(105)。所述方法可包括从所述第一中间层部件读取所述标记以确定所述第一引线框薄片的零件编号和引线表面纹理表层，从而通过与建立列表进行比较而验证所述第一引线框薄片的零件编号，并且仅在所述零件编号被验证的情况下才将所述第一引线框薄片转移到所述装配机器的安装表面上。
Abstract(English):

A method of making an integrated circuit (IC) device includes providing a stack of leadframe sheets each including a plurality of leadframes and an interleaf member interposed between adjacent ones of the leadframe sheets (101). The interleaf members include indicia that identifies the leadframes sheets (101). The stack of leadframe sheets is loaded onto an assembly machine (102). A first interleaf member is removed from the first leadframe sheet (103). The first leadframe sheet is transferred onto a mounting surface of the assembly machine (104). Semiconductor die are attached to leadframes on the first leadframe sheet (105).; The method can include reading the indicia from the first interleaf member to determine a part number and lead surface texture finish for the first leadframe sheet, verifying the part number for the first leadframe sheet by comparing to a build list, and transferring the first leadframe sheet onto a mounting surface of the assembly machine only if the part number is verified.
