In the diagram, the unit is shown with two rectangles representing the laser (blue) and the nozzle
(grey). Three ‘potential’ locations have been shown, top centre and bottom. At the centre, (white
outline) the unit can make a good contact height check. However, when the unit moves from the
contact height position to the range location, on the right, the board edge is not straight, therefore
the laser may not be ‘seeing’ the upper surface of the product, as depicted by the black outlined
rectangles (see incorrect range location).

Similarly, a feature under the laser on the bottom location is centred over a gap in the board where
the laser beam passes through. The contact height cannot be set. The user must choose a location
similar to that of the top track, where both the range and height checks can be carried out success-
fully.

2.4.2 Creating a Calibration Test Product
A calibration test product is a useful tool to have and can be created using a blank board. The
checklist for the test product should include positional accuracy tests and deposit consistency
checks.
Running a test product pre-production, exercises the system and eliminates any minor discrepan-
cies that may occur due to the physical properties involved in the process.
An example of a test product representative of a production board follows.
