Glossary
A
alternate feeder
An empty slot on a feeder table can be readied with the same part that is being supplied
from another feeder position. When the original feeder runs out of parts, the pick-up
position changes to this alternate feeder. Multiple alternate feeders can be specified.
When an alternate feeder runs out of parts, the next alternate feeder in the loop is used. If
the feeder is the last feeder in the loop then the original feeder is used again. If not using
dynamic alternate feeders (when using Fujitrax), then the alternate feeder positions must
be specified in the feeder setup.
assign
This is found in the coordinate data in the job and specifies which machine is to use the
mark or place the part/glue dot.
B
background
A term used for recipe conditions commonly for older Fuji machines. An portion of the
machine's memory used to stores recipes that aren't being used. A "background" recipe is
a recipe stored in this position. Conversely, active recipes are referred to as "foreground"
recipes. This term does not apply to the NXT and the term “next job” is used.
board
The smallest independent unit of a printed circuit board on which electronic components are
placed
BOM file
An acronym for "Bill Of Materials". The BOM file containes data such as part numbers for
each location that corresponds to a reference designator on the board. This file may
contain extra fields to add to the job's part data.
C
CAD file
A file which is output from a CAD system. This file generally contains the reference
designators, X,Y coordinates, and angles, etc., for each location on the board.
calibration data
Machine-specific data that is required for a machine to operate. An example of calibration
data would be the data that defines the spatial relationships between various machine
components.
CCIMF format
An intermediary file format. F4G programs and part data translated by Port Wizard are
output as CCIMF files. Recipes from Fuji Flexa and FujiCam are in CCIMF format.

centroid CAD
This is a text file that has the coordinates and reference designators for parts. Each line in
the file has data for one part only. Sometimes other data is present such as the part number
and panel side.
coordinate data
Data that displays in Job Builder, that has the position data and other necessary settings
for each part, mark, and glue dot.
current job
This is the job that is to be produced when START is pushed. This job is loaded in the
machine memory. There can be one current different job for each lane or the jobs for all
lanes can be the same.
D
Director
The Fuji Flexa component that is used for data management, transmission, and managing
factory lines and machines. In addition, this provides easy access to many of the other Fuji
Flexa components
dynamic alternate feeder
When using Fujitrac Verifier, it is possible to use alternate feeders without having to specify
a fixed position for them in the job. When using this function and a parts out warning is
issued, the operator prepares an extra feeder with a new reel of parts that are going to run
out, verifies it in Fujitrax and then sets the feeder in any open slot in the same module. The
machine checks what parts are on the feeder and then automatically changes the feeder
into an alternate feeder. When parts run out on the original slot, the machine will pick from
the alternate feeder.
E
element
A group of leads on the same side of a part that have the same length, width, and pitch.
F
fiducial mark
A mark that is used to adjust the positioning when parts are placed on a board. Fiducial
marks are printed onto the substrate together with the circuit pattern, thereby creating a
constant indicator of the pattern's present location. There are 3 types of fiducial marks: part
fiducials, board fiducials, and panel fiducials.
Fuji Flexa
This a production line host system for creating, editing, transmitting recipes to Fuji SMT
machines. In addition to the recipe management functions, the system is used for
monitoring the production status of the machines and managing machine specific data.
