形成预成型引线框的方法
摘要：
一种形成增加括脚的预成型引线框的方法，该方法包括以下步骤：将第一带附接到引线框的第一面和将第二带附接到引线框的第二面。将附接了带的引线框放进模具中，并开始模塑料的第一流。该模塑料的第一流填进第一带和模具的上模套之间的空间。然后，开始模塑料的第二流。该模塑料的第二流填进引线框的管芯焊盘和引线之间的空间。接着，将第一带和第二带从引线框中移走。由于模塑料的第一流压低了第一带，所以提供了增大的括脚。
摘要（英）：

The invention relates to a method for forming a pre-formed lead frame which expands an expanding pin, and the method comprises the following steps: a first band is attached to the first surface of the lead frame, and a second band is attached to the second surface of the lead frame. The lead frame with the attached bands is arranged in a mold, and the first flow of a molding compound is started. The first flow of the molding compound is filled in the space between the first band and an upper mold sleeve of the mold. Then, the second flow of the molding compound is started. The second flow of the molding compound is filled in the space between a tube core bonding pad of the lead frame and a lead wire. After that, the first band and the second band are removed from the lead frame. As the first flow of the molding compound presses down the first band, the method provides the expanded expanding pin.
