F 5
Fault 5
Contains all shutdown causes that resulted from malfunctions within the machine. 5
For SIPLACE Placement systems this includes Track Error, Fiducial Error, Barcode Error,
Transport Error, Air Supply and General Machine Errors. 5
I 5
Identification Error % 5
Ident Error % = (Sum identification error / (Sum placed Components + Sum errors)) * 100 5
Interrupted 5
Contains all shutdown causes that resulted from operator intervention. 5
For SIPLACE Placement systems this includes Emergency Stop, Cover Open, Stop Button
Pressed, Step Mode, Key Switch, Single Functions, Vision Menus. 5
M 5
Manufacturing Time 5
The sum of Productive and Standby. The equipment is ready (Idle) or is producing. No techni-
cal blocking factor. Engineering Time is not included. 5
MTBA 5
A measure of reliability denoting the average time between assists to restore machinery/equip-
ment to Productive condition. It is displayed for each individual station within the production
line for the evaluation interval. The MTBA is calculated as follows: 5
MTBA = (Tb - Tat / number of downtimes due to faults) 5
Tb = total operating time of the machine, or time basis for the evaluation period. 5
Tat = machine-related technical downtimes, e.g. unidentified reason, fiducial error, general ma-
chine malfunction, transport error, barcode reading error. 5
MTTR 5
The average time required to eliminate a malfunction and return the machine to Productive
condition is referred to as MTTR (Mean Time To Repair). It is displayed for each individual sta-
tion within the production line for the evaluation interval. The MTTR is calculated as follows: 5
MTTR = (Tat / number of downtimes due to faults) 5
Tat = machine-related technical downtimes, e.g. unidentified reason, fiducial error, general ma-
chine malfunction, transport error, barcode reading error. 5

O 5
OEE 5
Overall Equipment Efficiency 5
OLE 5
Overall Line Efficiency 5
Operational Uptime % 5
The percentage of time that the equipment is technically available for engineering or manufac-
turing use during the scheduled (Operations) time. 5
Operations Time 5
The production line is staffed, for planned activity, whether the system is operational or not. The
Factory/Line is scheduled for activity. Unknown time is not included. 5
Other 5
Scheduled Downtime, Non-Scheduled Time. 5
P 5
PCB 5
Printed Circuit Board. 5
R 5
Running 5
The station is carrying out placement operations and performing position and ink spot recog-
nition. 5
S 5
SMA 5
Standard Monitoring Application 5
T 5
Takt Time 5
Takt time = time of completion of board 2 - time of completion of board 1 5

Total Component Rejects 5
Total Rejects = (Sum Identification errors + Sum Vacuum errors) 5
Total Rejects % 5
Rejected % = (Sum Total Rejects / (Sum placed Components + Sum errors)) * 100 5
Total Time 5
Non-Scheduled and Operational Time. Unknown time is not included. 5
U 5
Unknown 5
System was powered off or disconnected. 5
Uptime 5
The equipment is available for use for either manufacturing or engineering. No technical block-
ing factors are present. 5
V 5
Vacuum Error % 5
Vacuum Error % = (Sum vacuum error / (Sum placed Components + Sum errors)) * 100 5
W 5
Waiting 5
Waiting for PCB in input or center conveyor, waiting on data supply. 5
