NOTE in re *)
If a plastic dust cover is still installed (earlier model), this must be replaced by the metal dust cover (see Sec-
tion 12.6.10).
12.6.7.1 Disassembly: Sensor Bracket
● Precondition: The "Preparatory Steps" (Section 12.6.6) must be completely finished.
CAUTION O
During the following steps, make certain that you do not damage the cable (bracket has sharp corners) or
place any strain on the cables.
● Undo the fasteners holding the dust cover on the machine base under the PCB conveyor module (three or
four washers and M4 socket-hex cap screws) and remove the dust cover.
● If a metal cover is over the flip-chip camera, removed it so that you can unplug the cables.
● Unplug the ribbon cable (illumination control) and the video lead from the flip-chip camera (see Fig.
12.6.8).
● Carefully loosen any cable ties along the ribbon cable.
● Undo the screws fastening the sensor cable to the sensor bracket (2 cable clips, 2 washers, 2 M4 socket
hex cap screws: see Fig. 12.6.8 -> 10).

● Unplug the connector of the "sensor cable coplanarity" on the sensor.
● Thread the "sensor cable coplanarity", the ribbon cable (illumination control) and the video cable in
through the hole in the sensor bracket (see Fig. 12.6.8 -> 2 and 6) and then out.
● Undo the screws fastening the coplanarity sensor to the sensor bracket
(three M4 x 3 socket-hex cap screws: (see Fig. 12.6.8 -> Pos. 8) and carefully put the sensor aside.
-> At least one of the 3 screws may be secured with Loctite but it must be loosened anyway.
NOTE:
If a dual conveyor is installed (stationary side on left or right) 2 spacer washers
HDFKRI
mm thick
must be placed under each screw fastening the sensor bracket. Make certain that these washers are not
lost when the bracket is dismantled.
● Undo the screws fastening the sensor bracket to the optional carrier (four M6 x 20 screws: see Fig. 12.6.8
-> 4) and remove the sensor bracket any any spacer washers under the screws.
12.6.7.2 Installation: Sensor Bracket
CAUTION O
While assembling the sensor bracket, secure the IC camera´s ribbon cable to prevent it from being
damaged.
During the following steps, be careful not to damage the cables (bracket has sharp corners) or exert any strain
on the cables.
● From inside of the sensor bracket, carefully thread the "sensor cable coplanarity", the ribbon cable (illu-
mination control) and the video cable from inside of the sensor bracket out through the hole in the side of
the sensor bracket to the right (see Fig. 12.6.8 -> 2 and 6).
● Fasten the coplanarity sensor to the new sensor bracket.
(three M 4 x 8 socket-hex cap screws: see Fig. 12.6.8 -> Pos. 8).
Do not fully tighten the screws yet: the sensor hasn’t been leveled (see below).
NOTE:
Fastening the sensor cable as follows ensures that the dust cover cannot cause damage to the cable.
● Connect the plug-in connector of the sensor cable to the sensor.
● Fasten the sensor cable to the side facing the IC camera to the sensor bracket (see Fig. 12.6.8 -> 9 and
10), 2 washers, two M4 x 8 socket-hex cap screws).

CAUTION O
In the case of SIPLACE machines with a dual conveyor (left-hand or right-hand conveyor side = stationary),
two
spacer washers 1 mm thick must be placed between the optional carrier and the sensor bracket per
fastening screw (see Fig. 12.6.8 -> 5. Item No.: see Section 12.6.2).
● Keeping the above NOTE in mind, mount the sensor bracket on the optional carrier
(four M6 x 20 screws: see Fig. 12.6.8 -> 4). Make certain that you do not pinch any cables.
● Reconnect the existing video and ribbon cable (= illumination control) to the flip-chip camera.
● Reinstall the cover over the flip-chip camera.
● Check that all cables have now been run and connected.
● Using a bubble level (accuracy = 0.4 mm/m) and a metal square, align the left-hand, vertical outside edge
of the sensor housing such that the sensor is exactly perpendicular to the IC head (Pick & Place head).
● While in this position, tighten the screws fastening the sensor.
No Loctite is applied to the screws (earlier module = applied).
● Assemble the machine as described in Section 12.6.14 "Final Steps".

12.6.8.1 Disassembly: Sensor Cable
CAUTION O
During disassembly and assembly of the control unit and all work inside the machine base, make certain that
you do not damage the cables or exert any strain on them.
Do not pull an existing cable harnesses and do not move them out of their position.
The sensor cable must be placed next to cable harness inside the machine base and fastened to it with cable
ties.
Precondition: The "Preparatory Steps" (Section 12.6.6) are completely finished.
● Disconnect the plug-in connection of the sensor cable on the "Coplanarity Processing Unit" (see Fig.
12.6.7 -> 7).
● Carefully push the sensor cable through the relief cut in the cover plate on the right into the control unit.
● Carefully remove the control unit. The cables must not be damaged.
● Undo the screws fastening the dust cover on the machine base, under the PCB conveyor module (three or
four washers and M4 sock-hex screws) and remove the dust cover.
● Disconnect the plug-in connection of the sensor cable on the sensor (see Fig. 12.6.8 -> 1, 7).
