✱✱Detailed Information
When bad placements have been found on visual board inspection, it is quite time
consuming to trace the badly placed SMDs back to the placement module(s) and
feeder(s) from which they originated. Especially if a lot of SMDs have been placed
on a board, and you need to search through the complete action spec.
By means of the SMD’s item code and the circuit number (as both used in the
action spec), the
[Trace component...] function gives you the possibility to easily
trace the errors back to the machine parts involved.
▼Displayed Information
On selecting the [Trace component...] command, the following dialogue screen will
appear:
fcm0546a.tif
SCREEN 5-37
Once the item code and circuit number have been entered, the MIS system will
start searching for the SMD in the action spec.
If the entered SMD parameters are found, the process graph of the placement
module where this SMD is used will be displayed (see SCREEN 5-41).
■ On top of the graph, first the input information is shown:
• the component (SMD) number to be traced
• the concerned circuit number

■ Next, the output information is given:
• the placement module, the feeder, and the pick position where the
selected SMD type has been processed

• the partnumber of the SMD reel that has been used for the selected SMD type
■ Below these informations, the process errors are displayed in bar-graphs, that
have different colours for each process error type. The amount of errors can be
read from the left Y-axis. This can either be in absolute numbers or in PPMs,
depending on the selected mode.
■ The number of placed SMDs are displayed in a line-graph. The amount of
placed SMDs can be read from the right Y-axis.
NOTE: The process errors that occurred on the traced SMD are displayed in bright
colours, the process errors for the other SMDs are displayed in pale colours.
■ The process errors are divided into auto retries and manual retries (see below).

SCREEN 5-39
• An auto retry is a retry without operator intervention (automatic); the
maximum allowed number of auto retries is determined in the action spec,
(see SCREEN 5-16).
• A manual retry is a retry by operator intervention. After the FCM Multiflex
has reached the auto retry number limit, it stops, and manual retries may be
done by the operator then. Note that only those manual retries are taken
into account for the process report that were successful at first attempt.
