Bridge detection ( I ): the short circuit detec-
tion feature can be activated by picking the op-
tion Bridge detection.
The short circuit detection can be set for all pads
by using the Paste tab in the test file configu-
ration window, or by using the Edit pad screen
to set each pad individually (with this way, the
propagation, propagation by topology and prop-
agation by jedec are available).
For each case the following parameters should be set:
The side of the pad to activate.
The maximum size of the bridge length. (0.100 mm is the default value defined in the .ini file,
under [Paste] keyword).

dow below appears.
9.4.1 Specifications tab
In
CAD position
(
A
) section, enter the CAD
X and Y coordinates of the paste deposit.
In Position tolerances (B) section, enter
the acceptable tolerance of X and Y on the
position of the centre of gravity of the paste
deposit found (in 1/100th mm).
In Surface (C) section:
S
: theoretical surface area of paste deposit.
Smin & Smax: minimum and maximum ac-
ceptable surface area of paste.

9.4.2 Special parameters tab
These parameters are dedicated to this
pad for solder paste detection. When these
parameters are set to 0 in this editing box,
the default parameters in the configuration
box of the .tst file are used for the inspec-
tion (see § 9.3.3 Processing parameters
for description).
9.4.3 Special parameters for flux tab
These parameters are dedicated to this
pad for flux detection. When these param-
eters are set to 0 in this editing box, the de-
fault parameters in the configuration box of
the .tst file are used for the inspection (see
§ 9.8.2 Flux detection parameters for de-
scription).
