E) Line information
Name Explanation
Spoilage Rate [PPM] The spoilage rate is calculated using the following formula.
Error sum total / Total pickup count
×
1000000
∗
Error sum total is a sum total of pickup errors, recognition errors,
drop errors, placement errors, thickness errors, and drop errors of
the transfer unit.
F) Production information
Name Explanation
a Panel Count The number of PCBs passed through the line
(Production count = No. of post-placement PCBs
+
No. of PCBs just
passed through)
b Pattern Count The number of patterns actually produced (placed)
c Running Rate[%] The rate of the time during which the machine actually performs the
placement process in the production mode
(Operation rate = Real run time / Run time)
d Running Time The time in the production mode
e Real Running Time Definitions of single-lane and dual-lane are different.
・
Single-lane:
The time found by subtracting the one while placement is stopped,
owing to an error or a wait for upstream/downstream processes,
from the one in the production mode
(Real run time = Run time
−
Total downtime)
・
Dual-lane:
The time found by subtracting the one while placement is stopped,
owing to an error or a wait for upstream/downstream processes, and
the transport time from the one in the production mode
(Real run time = Run time
−
Total downtime – Transport time)
∗
When the machine runs with dual-lane at optimum condition, there
will be no loss of transport time.
f Total Stop Time The machine downtime during production
g Spoilage Rate [PPM] The spoilage rate is calculated using the following formula.
Error sum total / Total pickup count
×
1000000
∗
Error sum total is a sum total of pickup errors, recognition errors,
drop errors, placement errors, thickness errors, and drop errors of
the transfer unit.
h B Displayed when the target machine is the bottleneck machine.
