Å Hold the retainer firmly (G in Fig. 10.8 - 1). Press the clamp (F in Fig. 10.8 - 1) downwards and
remove the retainer by pressing it out sideways.

10.9.1 Defining the Height Clearance
Height clearance means the distance between the upper transport edge of the PCB and the upper
edge of the component, i.e. 10
10
10
In other words, the height clearance specifies the height that a placement head needs in order to
avoid the risk of a head crash when holding a component. 10
10.9.2 How to Verify a Height Clearance of 21 mm with the Pick&Place Head
In the past, the height clearance for a 6x or 12x Collect&Place head when holding a component
was limited to 11.5 mm in order to prevent the risk of a head crash when inserting tall components.10
10
A recently implemented function now enables components with a height clearance of up to 21 mm
to be inserted with the IC head. To do this, the nozzle is removed from the Collect&Place head for
the entire duration of the program for a segment. During placement by the IC head, the segment
is rotated into the bottom star position without a nozzle. 10
10
In order to insert a component with a height clearance of more than 11.5 mm, the line computer
generates a nozzle configuration without a nozzle for the 6x or 12x Collect&Place head. A mes-
sage also appears on screen to inform the operator that 5 or 11 nozzles are in use. Before the
placement program starts, the Collect&Place head sets down the extra nozzle in the nozzle
changer. If no nozzle changer is installed, the operator is prompted to remove the nozzle manually.10
WARNING
The extended height clearance function is only suitable use with 12 - 72 mm tape feeder modules.
It is not intended for use with wafflepack changers, manual trays and linear conveyors. 10

Height clearance = PCB height + component height
