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.

Moving fiducial locations, during product run, may affect the location of sites. If 2Di or HawkEye are
used in conjunction with Stinger; moving sites results in a new pre-image being taken. In this in-

not need to be applied if fiducial locations are moved during setup.
