Pattern Recognition (XDLM 237)

21.4 Pattern Recognition: Measurements on Printed Circuit Boards

In the following, the pattern recognition is explained using

contact pads of SMD components

as an

example, see Fig. 21.3.

Figure 21.3: Printed circuit board panel with several individual printed circuit boards, datum points

1 and 2 serve as positioning aids

All settings for the pattern recognition are valid for one product. You can assign every product its
own settings for pattern recognition.

Before you start

You have installed at least version 6.30 of the WinFTM software and activated the WinFTM exten-
sion SUPER. You can determine the WinFTM version via

Help > About WinFTM...

Procedure

1. Program the XY coordinates for automatic measurement. Use the following options for this:



Same programming on multiple parts ( pattern), see Chap. 17.10 on page 139.



Datum points (two datum points), see Chap. 17.12 on page 142. If you program two
datum points, then the programmed XY coordinates will be reliably approached even with
a skewed positioning.

2. Select

Video > Pattern matching

in the menu bar.

The pattern recognition window appears.

3. In the

Saved pictures

area, click

Clear all pict.

Any video images saved previously in the product are deleted.

4. Activate the

With progr. XY-Pos.

option.

5. In the

Move to saved xy-coordinates

area, click

1. Position

The XY-stage moves to the first measuring position.
