PCB Clamp
–
Each fixture should provide a means to clamp the PCB down. This prevents the PCB
from being lifted when an insertion tool is retracted from a pressed connector. Also, the clamp holds
the PCB flat to the fixture.

CAPI-6T (Conveyor Loaded Press)
Support Fixture Plate
(Figure 34)
The press uses a custom fixture (similar to that used on the CAP-6T) specific to the PCB to support the
board during the pressing cycle. The fixture is located on the fixture support plate that is affixed to the
table top of the machine. The fixture support plate has fixture locating M6 dowel holes as well as M5 x 0.8
threaded holes.
An automatic conveyor system moves the PCB over the fixture plate, lowers it onto self-centering pins,
and then clamps the board in place. At the completion of pressing, the board is automatically unloaded
from the machine by the conveyor system.

CAUTION
Consideration must be given to any portion of the fixture that is close to the conveyor side rail, to ensure that the fixture height
and the Press tool length are adequate to prevent the press head from contacting these areas during pressing.

Height
–
The fixture height as measured from the fixture support plate is based on the PCB resting on
the fixture with the conveyor slightly below it. This height minimum is 32 mm [1.26 in.]. If the fixture
height is less than that, damage to the conveyor will occur. The maximum fixture height as measured
from the fixture support plate is based on the required clearance of components on the bottom side of
