Abstract
In the case of a curing installation, in particular for magazines with lead frames which are fitted with electronic chips, there is provided at least one box (R.sub.2) which can be closed by a door and in which at least one fan is arranged for subjecting the lead frames in the magazine to hot gas. The fan is supported on a housing of the box (R.sub.2) and is arranged in such a way that it produces in the region of the magazine at least one essentially horizontally directed gas stream essentially parallel to the longitudinal direction of the magazine, so that gas flows through the magazine. The fan may be designed as a helical fan or a radial fan, and the direction of the gas stream may be varied by reversal of the direction of rotation of the fan.
