Abstract

Electronic components are mounted on a substrate from thin-walled magazines which are arranged in a configuration corresponding to a desired implantation of the components. Stacks of components are pushed upwards in the magazines by a pulse of compressed gas in order to press the components against the substrate which has been arranged over the magazines with conductor tracks facing downwards. Local application of an adhesive solder paste to the substrate causes the component on the top of each stack to adhere to and be lifted simultaneously with the substrate.

Claims

1. A device for placing a plurality of components against a carrier in a given configuration, comprising

a plurality of tubular magazines formed with thin walls and adapted to contain respective stacks of components, each magazine having an open top end, an opening adjacent the other end, and transverse sections corresponding to the cross-section shape of the components to be contained therein,

a follower member disposed in each magazine arranged to have a friction fit with respect to walls of the magazine,

an element having an upper surface and a lower surface and holes extending from said upper to said lower surfaces, said plurality of magazines being disposed in said holes substantially parallel to each other, with their top ends arranged in said given configuration adjacent said upper surface,

a fluid-tight housing arranged so that said element forms a housing cover, said element being a plate having holes arranged in said given configuration, said magazines passing through said holes with top ends of said magazines being adjacent said holes;

said housing and cover enclosing a space, said openings adjacent the other end of each magazine communicating with said space; and

said plate further including means for positioning a carrier in aligned relationship with and adjacent said open top ends,

means for admitting a fluid under pressure into said space below said follower members, for pressing the top component of each stack against a carrier which has been positioned adjacent said open ends, and

a platform arranged within said fluid-tight housing for sliding movement arranged such that by sliding the platform the magazines may be extracted through the plate.

2. A device for placing a plurality of components against a carrier in a given configuration, comprising

a plurality of tubular magazines adapted to contain respective stacks of components, each magazine having an open top end and an opening adjacent the other end,

a follower member disposed in each magazine arranged to have a friction fit with respect to walls of the magazine,

an element having an upper surface and a lower surface and holes extending from said upper to said lower surfaces, said plurality of magazines being disposed in said holes substantially parallel to each other, with their top ends arranged in said given configuration adjacent said upper surface,

a fluid-tight housing arranged so that said element forms a housing cover, said housing and cover enclosing a space, said openings adjacent the other end of each magazine communicating with said space,

means for positioning a carrier in aligned relationship with and adjacent said open top ends, and

means for admitting a fluid under pressure into said space below said follower members, for pressing the top component of each stack against a carrier which has been positioned adjacent said open ends,

characterized in that said element is a block of an elastomer material arranged to constitute a cover of the housing, said magazines passing through and being supported in the desired arrangement by said elastomer which thereby positions said magazines,

said means for positioning said carrier includes elements embedded partially in said elastomer, and

said device further comprises at least one ejection element arranged to correspond to a reference point on a carrier, said ejection element including at least one portion moved by a spring force from a lower position to an upper position and a further portion of said element which projects slightly when said first mentioned portion is in the lower position.
