automatic placement system is equipped with a revolver placement head and an IC
placement head. Both placement heads are mounted on a common gantry.
The IC head is fixed to the gantry with two M4 x 16 or M4 x 25 fillister head screws. Two parallel pins ensure
that the IC head is mounted precisely on the gantry.

The z axis consists of the following principal components:
– Servo motor, tachogenerator and incremental encoder
– Synchroflex toothed belt
– Sleeve and
– End position BERO
The servo motor moves the sleeve in the vertical direction by means of the Synchroflex toothed belt. The res-
olution of the incremental position measurement is 27.7 digits per millimeter travel.The end position BERO
signals the upper sleeve position.
During the approach to the reference point, the z axis moves up to the upper stop, changes direction,
searches for the zero pulse and then moves to the 0 digit position by the amount indicated by the zero point
correction. The gantry axes must not start to move until
– the z axis is in the 0 digit position and
– the end position BERO has been activated.

The dr axis consists of the following principal components:
– Servo motor with tachogenerator
– Pair of friction wheels
– Incremental encoder
The angular resolution of the dr axis is 72,000 digits per 360°, i.e. 1 digit corresponds to 1/200°.
