11.12 Fine calibration

11.12.1 Overview

Fine calibration involves measuring the machine’s placement offset and determining the required

correction from this value. The ‘Fine calibration’ measuring program is integrated into the SITEST

program, and a detailed description of the measuring procedure is given in the ‘Fine calibration’

instructions (article no. 00191655-01). 11

CAUTION

The SITEST program is password-protected. It must only be called up and used by Siemens en-

gineers or appropriately trained personnel. 11

11.12.2 System requirements

The following system requirements must be fulfilled in order to use the fine calibration program:11

Machine type S-20/F

Station computer software version 406.xx or later

SITEST version 406.xx or later

11.12.3 Measuring equipment and tools

The following are supplied as standard: 11

– Mapping plate (glass plate in a metal frame)

– Double-sided transparent adhesive film

– Lighting unit

– Magazine with glass components for the collect&place head and pick&place head with fine-

pitch vision module.

The following items must be ordered: 11

– Manual tray (waffle tray holder) to hold the magazine for the glass components

(article number 00116430-xx)

The following parts may be ordered if required: 11

– Magazine with glass components for the collect&place head and pick&place head with flip-chip

vision module (article number 00343704-xx)

11.12.4 Functional description

First select the placement program for fine calibration by selecting the ‘Cluster for fine calibration’

option from the ‘Options’ pull-down menu. Then process the mapping plate with the glass compo-

nents from a magazine on the manual tray. 11

After placement, start the SITEST program and start the ‘Fine calibration’ measuring program.

The placement head (collect&place head or pick&place head) will measure the current placement

positions of the glass components and compare these positions with the circular fiducials on the

mapping plate. The results are used to calculate the offset values. 11

The offset values are used to determine corrected values, which are then entered in the machine’s

machine data. 11

11.13 Vacuum tooling

Vacuum tooling is another module that is used to increase the placement accuracy for concave

PCBs. The vacuum surface of this device picks up concave PCBs during processing and aligns

them so they are flat. 11

The vacuum tooling module can be used on both single and dual conveyors, and is fitted to the

lifting tables. 11

11.13.1 Description of the functions

The PCB is fed to the processing belt, where it is stopped. The lifting table moves up and the vac-

uum circuit for the vacuum tooling device is opened. The PCB is then held in place by the vacuum

tooling device, which is pressed with a spring action against the PCB by the lifting table. This

causes the suction cups of the tooling device to press against the PCB and hold it firmly in position.11

The vacuum channels are vented after placement. The lifting table is lowered, the PCB is re-

leased, and can then be moved on. 11
