ASM AVS - USER MANUAL
PAGE 6 OF 182
1 Preface
The product ASM AVS can be used locally at the customer's premises to perform machine capa-
bility analyses (MCT) of SMD placement machines.
Machine capability tests document the ability of a production facility (fitting machine), to be able
to fulfil a predefined processing task (fit at the debit position), durably and for certain.
1.1 Description of the measuring method
The employed method is a so-called relative measurement.
In this method, the position of the placed components is measured relative to a structure (grid of
dots with circular fiducials) applied to the employed glass board.
In the case of chip components such as ceramic pads, simple capture using the camera is suffi-
cient to determine the component offset.
In the case of glass modules (QFP or BGA structure), the position is measured relative to the
structure of the board at the 4 fiducials present in the corners of the component. The software
then calculates the center of the component on the basis of the position of the four corner
points.
1.2 Background
The service provided with ASM AVS includes a machine capability analysis of the customer's
placement machine together with the correction of any placement offset, with the result that
customers can be issued with a certificate of the precision (machine capability) of their place-
ment machines when the operation is complete.
1.3 History OnSite MCT
1. Fine Calibration to measure accuracy on machines with analogue Vision System.
2. CmController (4 worldwide) from CeTaQ: For onsite MCT with an external device.
3. ACT, to measure accuracy on machines with digital Vision System
4. Siscan AC (11 worldwide) in-house developement Siplace Service under Siemens AG:
For OnSite MCT with an external device.
5. After leaving Siemens and the sell out of Siscan technology:
Renaming of the system to ASM AVS.
6. ASM AVS 2.0: New design, new Software, to measure screen printers and placement equip-
ment from foreign manufacturers.

2 Details to AVS Device and accessories
2.1 ASM AVS
The ASM AVS device consists of 2 modules:
• Part 1: Computer with outbound interfaces.
• Part 2: Board seating, axis system with camera, background lighting.
2.1.1 ASM AVS lower part (03061515-02), part 1:
The lower part of the device contains a Siematic Box PC 827C.
This PC has the following tasks:
• Application of the ASM AVS software.
• Axis control (stepping motors)
• Measurement with digital SIPLACE Vision
• Control of the placement line (SIPLACE Pro)
2.1.2 ASM AVS upper part (03061131-01)
The upper part contains the axis system and the illumination unit for the background lighting.
The axis system, which is controlled with stepping motors, contains a standard PCB camera
from the SIPLACE X series.
The glass board with the placed components is fed into the system via a drawer.

2.1.3.1 Measurement plates
The measurement plate (Calibration board single kit 03056448-01) is a glass board (300 x 200 x
4 mm) on which a chrome structure has been applied on one side.
This glass board is glued inside an aluminum frame using silicon.
Knurled bolt
The cover is fixed to the
board frame using a
knurled bolt.
• Unscrew bolt.
Mounting
braket
On the other side (opposite the
bolt fixing), the cover is held in
place only by the mounting brack-
et.
• Raise the cover slightly on this
side.
• Next, push cover to left while
holding the board in the frame.
