Abstract
The assembling of integrated circuits takes place in a welding post in which a film bearing circuit units advances step by step. Each integrated circuit is brought into the welding post by a rotating platform driven step by step in synchronism with the film. The integrated circuits are loaded in a loading post angularly separated from the welding post and very slightly separated from the exact position they should occupy following their transfer to the welding post. The position error is corrected in an alignment post by simply sliding the integrated ciruit over the platform surface. Thus three operations may be simultaneously performed (loading, alignment and welding) on three individual integrated circuits.
