ABSTRACT OF THE DISCLOSURE During the assembly of electronic components on circuit boards, the problems of ductile smear cusps produced on wire ends by traditional scissor-type shearing are addressed by a spiral orbital shear apparatus. This apparatus includes a first fixed plate having an array of apertures and a second plate also having the array of apertures. The first and second plates have abutting surfaces. A first eccentric drive member is connected to rotate at a first rate in a first direction. A second eccentric drive member is connected to the second plate and rotates with the first eccentric drive member. The second drive member is also rotated at a second rate in the first direction independently of the rotation of the first drive member.
