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).

9.5 .spl files
The .spl file is a Solder Paste Library. It is an ASCII file containing solder paste parameters which can
be imported into a .tst file.
Use .spl file if you need to set specific parameters to pads according to their geometrical properties or
according to their affected components.
To create a .spl file, go in Editor menu and select Open a text file. Choose the .spl file type. The text
editor window appears.
There are 2 files format. The first is based on pad geometry (length and surface) and the 2nd on
JEDEC.
9.5.1 .spl file based on pad geometry
The 2 first lines create different geometrical sol-
der paste pad models (in this case 16 different
models).
A Min (dimX , dimY): 0.33; 0.5; 1 create differ-
ent classes based on the minimum pad size
(if dimX < dimY we take care of dimX and
vice-versa).
B Surface: 0.52; 0.8; 1 create different class
base on the pad surface.
C These parameters will be imported in solder
paste pads which have:
DimX or dimY < 0.33
Surface < 0.52
D These parameters will be imported in solder
paste pads which have:
0.5 < = dimX or dimY < 1
0.52 < = surface < 0.8

9.5.2 .spl file based on JEDEC
The first line must be jedec file otherwise Vision 2007 does not
recognize that it is a .spl file based on JEDEC family.
As for this .spl file format, when you import it into a .tst file, the
.spl file parameters are automatically entered in pads parame-
ters according to their JEDEC name.
9.5.3 .spl file importation
To import a .spl file, open the .tst file and in Test file menu go to Import and select Solder paste
file. The Open window appears. Select the .spl file you want to import.
In the .tst file, when you click on a paste pad, the imported .spl file parameters appear on the
Special parameters and Special parameters for flux tabs in the Pad edition window.
It is important to have linked pad to component (see
§ 9.2.2 Link pads to components) before importing
this kind of .spl file, otherwise all pads are pPaste JE-
DEC.
