The X axis essentially consists of the following main modules:
– Gantry arm (1)
– Head mount with X-axis linear motor (primary part) (2)
– Linear distance measuring system (3)
– Guide system (4)
– Permanent magnet (secondary part of the X-axis linear motor) (5)
– Cable and hose carrier (8)

The head mount (2) holds the following components:
– Sub-gantry camera (PCB camera for the PCB vision module) (6)
– Set of head boards (7)
– Measuring head for the measuring system
– Collect&Place CA head or SIPLACE TwinHead
The gantry arm (item 1 in fig. 3.12 - 3
) is made of a carbon fiber compound, which makes the mod-
ules extremely light while, at the same time, being very rigid.
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.
