ABSTRACT:
A combination lead straightening, lead aligning, and dielectric spacing implement for a semi-conductor package of the so-called TO (transistor outline) type. The implement has a generally annular body with hook-like formations or fingers spaced about the perimeter of and projecting into the body opening in a manner such that the implement may be installed on a semi-conductor package by inserting its leads through the body opening in the regions between the fingers and then rotating the body relative to the leads to engage the fingers in gripping relation about the leads. The leads are straightened by sliding the implement along the leads and are aligned with lead receiving holes in a circuit board or other mounting base for insertion into the holes by seating the implement on the base with its fingers aligned with the holes. The implement may be left on the leads of the semi-conductor package after installation on the base to space and insulate the body or can of the package from the base.
