Otherwise, this may result in damage to the PCB and or the mechanical ceramic substrate

centering unit (X-centering unit).

Å Select "Accept" to exit the "Machine configuration" menu.

If the selected menu option differs from the hardware situation "mechanical ceramic substrate

centering unit present/not present", when you exit this menu an error message or note will be

output, as described above during the configuration of conveyor 1.

Å Exit the SITEST program.

Å Carry out the shut-down the machine and execute a machine restart so that the configuration

will be accepted.

Å Check the function of the mechanical ceramic substrate centering unit (see Section 2.7).

Å Check WITHOUT substrate, whether the mechanical substrate centering unit opens and

closes correctly, i.e., whether the proximity switch (control LED) and solenoid valve operate

properly and the restrictor is set correctly.

Å In the "Transport functions" menu click on the button "

" in the

field "Processing area 1".

Ceramic substrate centering unit 1 will open.

Å Click on the button "

&HUDPLFVXEVWUDWHFHQWHULQJ

" again in the field "Processing area 1".

Ceramic substrate centering unit 1 will close.

Å Make certain that the lifting slide of the centering unit doesn’t bounce upon opening or it

opens too slowly:

- If it opens too slowly, the proximity switch signal does turn to 1 but it does so too late.

- If it bounces, the proximity switch becomes free again (signal 1 -> 0 -> 1).

Å If there is an error, correct the setting of the restrictor for the opening movement appropri-

ately (see Fig. 2.5.4 -> 7).

Å Proceed in a like manner for "Processing area 2".

Conduct the following test run with substrate to check the function of the substrate centering unit

during the conveying process (lifting table up/down) and simultaneously to visually inspect that

the substrate is properly centered and thus that the stopper position is also correct.



NOTICE

These jobs must be carried out for each ceramic substrate centering unit, i.e., for each processing

area.

When the centering unit is open, the substrate edge pointing in the direction of the unloader must

still be 0.5 mm IN FRONT OF that of the unmovable roller of the fixed stop (see Fig. 2.7.2). When

the substrate is raised while the centering unit is moving upward, the stopper position must be ad-

justed in the direction of the X-centering station. 

Å Select the menu "Transport functions".

Å Place the substrate on the input belt

Å During the following step, keep an eye on the substrate and the closing movement of the X-

centering unit. The substrate is not to raise.

For the corresponding conveyor (processing area), select: PCB onto processing belt 1.

Å If the substrate is lifted when the open centering unit moves upward, you must adjust the

stopper position (see Section 2.7.3).

Å After the lifting table is raised, the x-centering unit close due to the tension spring on the flat

cylinder (no pressure applied, proximity switch signal = 0).

If an error message is displayed, see Section 2.7.4.

Å Select:PCB onto intermediate belt.

The X-centering unit must open before the lifting table moves down (pressure applied, proxim-

ity switch signal = 1

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

cessing belt 2.

Å Select: PCB onto processing belt 2.

Å If necessary correct the stopper position (see Section 2.7.3).

Å Select: PCB onto output belt.

Å If the stopper is in the right position, conduct a trial placement with substrate and check

whether the fiducials of the substrate can be reliably recognized. If necessary, select a different

type of illumination (see User Manual).
