Abstract
A process for mounting chip type circuit elements on printed circuit boards and apparatus therefor are capable of eliminating the necessity for arranging an X-Y table, thereby to simplify the structure of the apparatus, and decreasing the time required to mount one circuit element on a printed circuit board. Chip type circuit elements are sucked up by a plurality of suction pins arranged in each mounting head, transferred to a centering and turning section and then progressively mounted on a printed circuit board. The mounting head is adapted to carry out the reciprocating movement in the X-direction a plurality of times while it carries out the reciprocating movement in the Y-direction one time.
