Calibration of SIPLACE HS-50

Calibration Steps

The different calibration steps are integrated in the SITEST test software.

With „calibrate heads and cameras“ the following sequence is executed automatically

Ø calibrate the PCB-camera

Ø calibrate the component-camera

Ø execute the segment offset I (above)

Ø execute the segment offset II (below) and the camera camera offset

Ø calibrate machine zero point

Ø calibrate nozzle changer

Ø calibrate the P&P (IC)-camera with P&P head the Flip-chip-camera

Additionally manual work

Ø calibrate the pick up height of nozzles

Ø calibrate coordinates at the PCB transport

Ø calibrate component table positions

Ø calibrate the coplanarity module (option)

Before starting calibration

Ø program Star axis zero point correction

Calibrate PCB camera

In this menu we determine:

Ø the mechanical Pixel size of the CCD-sensor

in µm.

This is calculated with the calibration

factors „Kalibrierfaktoren“ AX/BX/CX ...

Saved in REAL.MA

XU_Pixel / YU_Pixel. (in 11500nm)

Ø the camera center pixel.

Ø the angle of the CCD-Sensor according the

machine coordinate system.

Saved in REAL.MA

“Kamera_offset_Winkel“

Ø the camera offset is done with segment offset

Ø the camera center pixel.

Ø the angle of the CCD-Sensor according the

turning level of the Placement Star.

Saved in REAL.MA „Kamera_offset_Winkel“

Ø the camera offset is set to Zero (because the

camera center is the reference for calibrations).

Segment offset II

The sequence at segment offset bottom / II is:

Ø We center the actual calibration tool position

with the PCB camera. Then we pick it up

and center it optically in the component

camera. The moving distance and the com-

ponent offset is taken for the result.

Ø With segment number 1 we calculate the

distance between the two camera centers;

called (RV-head) camera (PCB) camera

offset. This is saved in REAL.MA in the data

bloc of the PCB camera.

KAMERA_OFFSET_X

KAMERA_OFFSET_Y.

Ø All other segments get an OFFSET to this

segment 1;called segment offset II of this

segment .

Ø This is saved in PIP_OFF.MA file

Pcb camera - component camera offset

With segment number 1 we calibrate the distance

between component -and PCB-camera center;

called (RV-head) camera - (PCB) camera offset.

The machine center optically PCB camera the

calibration tool in the “tool pocket”. This

calibration tool is picked up with segment number

1 and optically centered in (RV) component

camera.

The travel distance of PCB camera from the

measured tool position to the measured actual tool

center position is measured.

This measured distance is set for the camera -

camera distance. There is not maximum limit set

for.

The component camera center is set for the

reference position.

Segment offset I

0°

180°

With this menu we determine:

Ø the mechanical distance between center of the

component camera to the center of the turning axis

of the segment in µm.

This is calculated with a 180° turning of the

calibration tool on the nozzle.

Saved in PIP_OFF.MA.

Ø Picture 1 segment with calibration tool in 0° under

the camera. DP station turn than in 90° steps and

on each angle this measurement is done.

Ø First measurement results from 0° and 180° taken

to calculate turning axis.

The plausibility check is done with

the results from 90° and 270°.

Ø Picture 2 segment with calibration tool in 180°

under the camera.
