A support assembly comprises a support device and a plurality of press-fit contact pins. The support device has a preformed body with a first row of slits or holes and a second row of slits or holes. The press-fit contact pins each have a contact portion at a first end and a press-fit portion at a second end opposite the first end. Each of the contact pins is disposed in one of the slits or holes of the first row or the second row with the press-fit portion protruding from a first side of the support device and the contact portion protruding from a second side of the support device opposite the first side. The press-fit portions of the contact pins disposed in the first row of slits or holes are aligned with the press-fit portions of the contact pins disposed in the second row of slits or holes.
