In known pick-up heads for orienting electrical components the component, supported by a pick-up tool, is engaged by a plurality of pairs of opposed jaws to urge the component into a desired orientation. When the components become oriented, the pairs of jaws exert a slight gripping force on the component which can damage fragile components, for example so-called "chips". In the invention, a datum face of the pick-up tool against which the component is supported has the same peripheral shape as the component but each dimension is slightly larger than the corresponding dimension of the component and orienting faces of the jaws are disposed to engage the periphery of the pick-up tool when the component is oriented so that the components are not gripped between the pairs of jaws. Likelihood of damage is thus reduced. |
