The conveyor rear rail is mounted on bearing blocks with dual ball screws on the Y-axes (front-to-back
direction). The position of the rear rail can be manually adjusted to the desired width of the PCB by means of a
hand crank knob inside the front cabinet of the machine. The Autoload conveyor is pneumatically raised for
PCB loading/unloading and uses belts to transport the PCB through the machine. Pneumatically actuated hard
stops locate the PCB at the correct position above the pressing fixture during loading.

Configurations
In-Line
The CAPI-6T Autoload option allows the press to be incorporated into a SMEMA left-to-right automated
PCB processing line (Production mode) and a SMEMA right-to-left automated PCB processing line
(Reverse Production mode). Changing modes requires a software configuration change and that the
SMEMA cables be exchanged from side to side. After the appropriate software configuration settings are
modified (contact TE Service for specifics) and the AEP application is restarted, the machine may require
a power cycle to complete the mode change. With regard to the cables, the SMEMA connector on the left
side of the machine is always the “upstream” connector and the SMEMA connector on the right is always
the “downstream” connector. Logically, operating the machine in
Reverse Production mode flips the
“upstream” and “downstream” directions; this requires the SMEMA cables be routed from the opposite
sides of the CAPI-6T, to the adjacent inline machines.
If the press is located at the beginning or end of a PCB line, then a Conveyor Extension (2018690-1) must
be attached to the left or right side of the press. The Conveyor Extension provides a safe PCB loading (or
unloading) position for the processing line and provides required safety guarding for the end of the press
that is not protected by an adjacent machine. A Conveyor Extension may also be required on the left side
to allow longer boards to completely load and buffer on the Autoload infeed conveyor.
Stand Alone
The CAPI-6T Autoload option can also be configured for stand-alone use (Reverse Shuttle mode). This
mode requires a Conveyor Extension attached to the right side of the press and safety guarding (block-off
plate) attached to the left side of the press. In this mode the conveyor loads a PCB from the Conveyor
Extension. After pressing, the PCB is returned to the Conveyor Extension for operator removal. This
machine configuration is also available under TE part number 1689700-3. See Figure 38.
