A 5

Availability % 5

The availability of a station is a value permitting an assessment of the "technical quality" of the

station and the placement/gluing process carried out thereon. Organizational or structure-re-

lated downtimes must not have any impact on the availability. The availability of a station is cal-

culated as follows: 5

Availability station [%] = 100 x (1 - (Tat / Tb)) 5

Tat = machine-related technical downtimes, e.g. unidentified reason, fiducial error, general ma-

chine malfunction, transport error, barcode reading error. 5

Tb = total operating time of the machine, or time basis for the evaluation period. 5

B 5

Blocked 5

Waiting until output conveyor/center conveyor is clear. 5

Build Time 5

Build time = End of board processing in the processing zone - Start of board processing in the

processing zone 5

C 5

Component Sum 5

Component Sum = (Sum placed Components + Sum errors) 5

CPH 5

Component per hour 5

CPH = (Component Sum / Evaluation Time) 5

D 5

Downtime 5

The sum of Scheduled and Unscheduled Downtime 5

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
