ABSTRACT:
An apparatus for placement of electronic components on a fluxed hybrid circuit substrate. In accordance with an automated program, the apparatus at a single work station places with high precision a plurality of chips of various types and physical and electrical sizes on a single substrate. Components are successively placed by a pair of hollow pick and placement spindles operating alternately and having motion in the X-Y planes. Precise location of stored chips is not required; the apparatus orients and centers each chip after selection and prior to placement.
