5.1 Overview Gantry
The 2 gantries of the HF machine or the three gantries of the HF3 machine consist of one X- and
one Y - axis. Both axes are driven by a linear motor which is equipped with an integrated temper-
ature sensor. The Y-axis moves from the right to the left side in positive counting direction if you
look in transportation direction, the X-axis moves from the the input conveyor to the output con-
veyer in positive counting direction. The placement heads are mounted on the head plates of the
respective X axis.

Legend:
Please Note: On the HF machine are only two gantries. The name of this Gantries with Sta-
tionsoftware 505.xx are Gantry 1 and Gantry 3.

Legend
Instead of the normal PCB camera (sensor type 5.sst). You can use the option multicolor camera
(sensor type 18.sst).
The advantage of the multicolor camera is the fiducial recognition on ceramic substrate on ac-
count of different illumination colors.

5.1.1 Mechanical structur of the X- and Y- axes
Please Note:
X- and Y- Axes have the same basic mechanical parts.

Please Note: The temperature sensor compensates according the temperature of the head
mounting plate the offset between PCB camera and nozzle to ensure the highest accuracy.
(1) X-axis (carbon fiber composite material) (2) Head mounting plate with integreted temperatur sensor
(3) Incremental scale X-Axis (4) Linear guidance (above/below the magnet)
(5) Secondary part X-axis (Magnet) (6) PCB-camera below the X-axis
(7) Boards (Head interface with Vision board
below -vertical- is the Adapter board)
(8) X- trailling cable
