The X axis mainly consists of the following modules:
– Gantry arm (1)
– Head mount with X axis linear motor (primary part) (2)
– Linear distance measuring system (3)
– Guidance system (4)
– Permanent magnet (secondary part of the X axis linear motor) (5)
– Trailing cable (8)

The head mount (2) takes up the following components:
– Sub-gantry camera (PCB camera of PCB Vision module) (6)
– Set of head boards (7)
– Measuring head for measuring system
– Placement head
The gantry arm (item 1 in fig. 3.11 - 2
) is made of a carbon fiber composite. This technology allows
assemblies to be made with extremely low weight and high rigidity.
The X axis is driven by a linear motor. The secondary part of the drive consists of a permanent
magnet and is mounted on the gantry arm. The primary part is bolted to the head mount. The head
mount is designed to work with all placement head types - another reason for the high flexibility
achieved with SIPLACE placement machines.
