5. Move the adjustable rail back 180 mm from the fixed rail and measure at

points 4, 5 and 6. Finally, repeat for points 7, 8 and 9 at 250 mm from the

fixed rail.

6. Ensure that points 1, 3, 7, 9, 10 and 12 are within range.

7. To adjust, move the adjustable rail back to 180 mm and use the lock nut

jig and allen wrench to raise or lower the two rear corners until both

points 4 and 6 fall within or up to 0 ± 0.1 mm from point 1.

8. Raise and lower the fixed rail using the two (2) adjustment bolts as

shown in the diagram below.

9. Total tolerance for the whole board is 0.15 mm (if possible 0.1 mm).

1.5.5 Fixed Rail Linearity

Once the table top and clamper parallelism adjustments have been carried out, confirm

and if necessary, adjust the linearity of the fixed rail. Failure to straighten the rail within

permissible limits will result in clamping problems or skewed PCBs.

Procedure:

1. With all the clamper claws on the fixed rail open, position the dial on the

vertical edge of the clamper claw at position A (refer to diagram on the

opposite page).

2. Set the dial gauge to zero and inch in the X-direction at 1% inching speed

to position B. Note the dial gauge reading.

3. Inch from position B to position C and note the dial gauge reading. The

dial gauge should show no more than a 0.1 mm deflection at either point.

4. If the dial gauge deflection exceeds the permissible tolerance, loosen all

bolts as shown in the diagram opposite.

5. Again, zero the dial gauge at position A, and inch to position B. If the

deflection exceeds 0.1 mm, tap lightly on the clamper at point C until the

dial gauge registers zero. Zero again at point A, and inch to B. If at zero,

partially tighten the allen bolts at point E and F.

6. Inch to point C. If out by 0.1 mm or more, holding the rail at C, push

until the dial gauge reads zero and partially tighten the allen bolts at

point G and H.

7. Zero the dial again at position A and repeat the measurement. If all

values are within the tolerance, fully tighten all bolts and finally recheck.

1.5.6 X-Direction Clamper Linearity

Procedure:

1. Place the dial gauge against the side of one of the clamper claws on the

movable side and set to zero (refer to diagram on opposite page).

2. Inch in the X-axis till the dial reaches the same position on the fixed

clamper claw and note the dial gauge reading. The maximum

permissible tolerance is 0.2 mm.

3. If outside the range, attach a dial gauge to the front left and right hand

sides of the XY-table, set to zero, and loosen the 13 bolts noted in the

previous diagram.

Note: The dial gauges are used to ensure that the results of the previous adjustment are not

affected.

4. With dial gauge against the side of the claw on the fixed side, lightly tap

the clamper in the X-direction until the dial gauge reads zero, while

ensuring that the readings on both dials on the XY-table still read zero.

5. Tighten all bolts and recheck.

6. Finally, tighten all the clamper claws, ensuring a gap of at least 0.1 mm.

1.5.7 Reference Pin Adjustment

Procedure:

1. Install the refernce tooling pin and spring..

2. Set the dial gauge against the side of the pin on the rear side. Inch

slowly back and forward to find the highest point.

3. Inch the dial gauge until contact is made with the clamper claw. Ensure

the distance is betwen 7 andd 7.2 mm. Adjust the fixed clamper in the Y-

direction while maintaining the linearity.

1.5.8 Claw Fastening

Procedure:

1. Insert a 0.45 mm feeler gauge between the claws and the side of the claw

holders of the two center claws, and a thin feeler gauge such as 0.1 mm

under the claws themselves, hold down and tighten.

2. Finally tighten all the remaining claws.
