ABSTRACT:
Apparatus and method for aligning the leads of electronic devices having a body portion and plurality of leads extending from the body portion having pads at the free terminal ends comprising means for positioning the electronic device at a lead straightening station. A pair of lead straightening heads comprised of a plurality of fingers engages between the leads on opposite sides of the electronic device. The lead straightening heads are actuated relative to the electronic device through a straightening cycle including a first phase where the fingers engage between leads of the electronic device while in a floating condition and a second phase after the electronic device is clamped in place on a support surface to pivot the leads on either side of a plane extending transversely to the body portion and thereby align each of the leads relative to this plane. Coplanarity means is provided for positioning the pads of the leads so that they all lie in a common plane.
