12/2004 Edition 2.10 Activating the option

menu.

In the following cases, a note or an error message appears on screen:

– A note appears if you select the SITEST menu option "None" or "Oblique lighting", i.e. a

menu option without mechanical ceramic substrate centering, even though the mechanical

ceramic substrate centering hardware is still installed.

The note text says that the mechanical ceramic substrate centering unit must be removed

from the corresponding conveyor and the plug-in connections on the conveyor control con-

version board must be detached before continuing.

Otherwise the PCB and / or the mechanical ceramic substrate centering unit (X axis cen-

tering unit) may be damaged.

– An error message appears if you select the SITEST menu option "Mechanical" or " Mechan-

ical and Oblique lighting", i.e. a menu option with mechanical ceramic substrate centering,

even though the mechanical ceramic substrate centering hardware is not or is not fully in-

stalled.

The message states that the option is not installed in the corresponding conveyor or, if the

option has been retrofitted successfully, the corresponding plug-in connection on the con-

veyor control is missing or is poorly or incorrectly inserted.

: If a dual conveyor is used, then select from the Edit menu:

"Ceramic substrate centering conveyor 2".

Configure the mechanical substrate centering as described above for conveyor 1.

Note the possible combinations between conveyor 1 and 2, however:

– The combination of "None" and "Mechanical substrate centering" is possible if the conveyor

concerned is set up accordingly (with or without mechanical ceramic substrate centering).

– It is not possible to combine position detection with oblique lighting on one conveyor and

normal lighting or "None" on the other conveyor. If this combination is selected, the position

detection with oblique lighting is automatically adopted for both conveyors. In this case, the

mechanical ceramic substrate centering option is always removed from both conveyors and

the plug-in connections must be detached on the conveyor control conversion boards.

Otherwise the PCB and / or the mechanical ceramic substrate centering unit (X axis cen-

tering unit) may be damaged.

: Click on "Accept" to exit the "Machine Configuration" menu.

If the selected menu option differs from the situation defined by the hardware (mechanical ce-

ramic substrate centering present / not present), an error message or note as described above

appears if the machine is configured for conveyor 1.

: Exit the SITEST program.

: Shut down the machine and restart in order to accept the configuration.

2.11 Checking the functions 12/2004 Edition

: Check that the setting was made correctly.

: Test the mechanical ceramic substrate centering functions.

2.11 Checking the functions

2.11.1 Check the functions of the X-axis centering unit, WITHOUT substrate

: WITHOUT a substrate, check that the mechanical substrate centering opens and closes cor-

rectly, i.e. that the proximity switch (control LED) and solenoid valve are working correctly and

that the reducing valve is set correctly.

: In the Conveyor Functions menu, click on the Ceramic substrate cent. button in the "Process-

ing area 1" box.

Ceramic substrate centering 1 is opened.

: Click on the Ceramic substrate cent. button again in the "Processing area 1" box. Ceramic

substrate centering 1 is closed.

: Make sure that the lifting carriages of the centering unit do not bounce while opening or open

too slowly.

- If they open too slowly, the proximity switch signal may be 1, but it arrives too late.

- Bouncing causes the sensor to become free once more (signal 1 -> 0 -> 1).

: In the event of an error, correct the reducing valve setting for the opening movement accord-

ingly (see Fig. 2.8 - 1 -> 7).

: Repeat the procedure described above for "Processing area 2".

: Then continue with the check and adapting the stopper position.

12/2004 Edition 2.11 Checking the functions

2.11.2 Check the overall functioning and the stopper position, WITH substrate

Use the following test sequence with substrate to check the substrate centering functions in the

transport sequence (lifting table up / down) and, at the same time, carry out a visual inspection to

check that the substrate and thus the stopper position are centered correctly.. 2

NOTE

These tasks should be carried out for every ceramic substrate centering mechanism, i.e. for every

processing area.

When the centering mechanism is open, the edge of the substrate pointing towards the output

must still be 0.5 mm IN FRONT of the fixed roller of the fixed stop (see Fig. 2.7 - 2).

If the substrate is lifted when the centering unit is raised, then the stopper position in the direction

of the X-axis centering unit must be adapted accordingly. 2

: Select the "Conveyor Functions" menu.

: Place the substrate on the input belt.

: During the following sequence, watch the substrate and the closing movement of the X-axis

centering mechanism.

-> The substrate must not be lifted.

For the conveyor (processing area) under consideration, select -> PCB on processing belt 1.

: The stopper position must be adapted if the substrate is lifted when the opened centering unit

moves up (see Section 2.7).

: Once the lifting table has been raised, the X-axis centering unit must be closed by the tension

spring on the flat cylinder (when depressurized, sensor signal = 0).

If an error message is output, see Section 2.12.

: Select: PCB on intermediate belt.

The X-axis centering unit must open before the lifting table is lowered (pressurized, sensor sig-

nal = 1).

: Carry out the function check described above and check the substrate/stopper position for pro-

cessing belt 2.

Select: PCB on processing belt 2.

Correct the stopper position if necessary (see Section 2.7).

: Select PCB on output belt.

: If the stopper position is OK, carry out a test placement with substrate and check that the fidu-

cials on the substrate are detected reliably.

: Select another method of illumination if necessary (see operating instructions).
