Abstract
A freely positionable placement head (1) removes presented flip chips (6) from a wafer (5), the connection side of said chips being directed upward. The placement head has a turning device (9), in which, by the time they are placed onto a substrate (8) to be provided with placed components, the flip chips are turned in such a way that they can be placed with their connection side onto the substrate. This makes it possible to dispense with a complex turning device assigned to the wafer (5).
Claims10
A device for placing flip chips on a substrate in the form of a leadframe, the device comprising a movable placement head, which picks up the flip chips from a stock of components and places them on the substrate, the placement head being provided with a flipping device for the flip chips, the placement head being provided with a multiplicity of grippers circulating in a turret-like indexed manner, the flipping device being assigned to a stationary part of the placement head, the flipping device taking one of the flip chips in a first holding station of the grippers and after flipping the chip, returning the flipped chip to one of the grippers in one of the downstream holding stations.
