The invention relates to a device for inspecting and rotating electronic components, particularly flip chips, comprising a component which is rotatably mounted at a position of rotation and which is used to rotate electric components. A first receiving element is fixed to the outer side of the component in order to receive a single electronic component of a carrier and to secure it during a rotational movement of the component. A second receiving element is arranged on the outer side of the component opposite the first receiving element in relation to the point of rotation such that when the component is rotated by 180° it respectively faces the carrier, and a through opening is arranged in the component between the receiving elements such that when the component is rotated by 90° or 270° the through opening faces the carrier. The invention relates to a method for inspecting and rotating electronic components, particularly flipchips.
Method for checking and rotating electronic components, in particular flip chips, which are picked up individually from a sandwich of electronic components arranged on a substrate, by means of a first pickup element arranged on a pivoting part, and are deposited in a rotated position, the pivoting part being placeable between the substrate and a first optical facility for checking the surface and the correct position of a single component arranged on the substrate, characterized in that during a 180° rotation of the pivoting part a pickup by the first pickup element of a single electronic component arranged on the substrate, a check of a surface and the correct position of a further electronic component arranged on the substrate, by means of the optical facility and a through opening arranged in the pivoting part, a depositing of the electronic component held by the first pickup element on a placing facility after a 180° rotation of the pivoting part and at the same time a further pickup of the further individual electronic component arranged on the substrate, by a second pickup element arranged externally opposite the first pickup element on the pivoting part, are executed.
