A set of suction heads can be mounted to the head carrier in any desired arrangement, corresponding to the desired chip arrangement on the circuit board, by having their holders removably engaged in selected ones of the array of mounting holes in the head carrier. The template assembly is likewise made adaptable for a variety of chip arrangements, by having a set of open-top positioning vessels removably engaged in selected ones of an array of mounting holes formed in a template.
