• Working Ratio
This is the machine unit's working ratio. This ratio is not affected by the status of the upstream and downstream
machines, and is calculated with the following expression. Generally, the mounter working ratio is 40 to 70%.
Cumulative mounting time on all stages + cumulative transfer time on all stages
[
(Production completion time - setup completion time) on all stages - cumulative standby time on all stages
]
s 100
Working ratio (%)
=
• Cumulative mounting time : Total time that head is operating
• Cumulative transfer time : Total transfer time (board loading/unloading)
• Cumulative standby time : Total standby time due to upstream or downstream machine
• Production completion time : Time changed to next production board
• Setup completion time : Time [START] button was pressed and operation started
• [Reset] button
Resets the production control information, including each data and current production quantity, current unloader
quantity, scheduled production quantity and scheduled unloader quantity. The "Board Counter" value on the Setup
screen is also reset when this production data is reset.

Starting and ending production
4.3 Detail
The [Monitor]-[Detail] tab screen shows the detailed production status of the current production board data.
Monitor: Detail

• Start Time
Shows the time that production was started (time that board selection was completed). The quantity is normally zero
boards.
• Last Modification Time
Shows the display data update time. The quantity is the number of boards produced up to the present time.
• Estimated End Time
Shows the estimated production end time. The quantity is the scheduled production quantity entered on the Setup
screen. Note that this will be blank if the scheduled production quantity has not been entered.
• Supply Time (sec/board)
Shows the average loading time per board on the entrance-stage conveyor.
• Supply: Delay Time (sec/board, sec)
Shows the time that the machine has waited for board loading to the most upstream stage. Note that when the machine is
mounting components, the delay time will not be counted even if the board is standing by. The average delay time per
board or the cumulative delay time can be displayed by pressing the [Unit Change] button.
• Rest (boards)
This is the value obtained by subtracting the production completed board quantity from the scheduled production
quantity.
• Assemble Time (sec/board, sec/block, sec/chip)
Shows the time for mounting components on a board. This time includes the mark recognition (fiducial, bad mark, etc.),
component pickup, component recognition, mounting, dispensing, retry operation, nozzle change and component dump
time, etc. The average time per board, average time per block or the average time per chip can be displayed by pressing
the [Unit Change] button.
• Error Stop Time (sec/board, sec)
Shows the time that the machine has been stopped with an error, and is the total time from when the error occurs to
when the [CLEAR] button is pressed. Note that the time for recovery is not included. The average error stop time per
board or the cumulative error stop time can be displayed by pressing the [Unit Change] button.
• Output Time (sec/board)
Shows the average unloading time per board on exit-stage conveyor.

Starting and ending production
• Output: Delay Time (sec/board, sec)
Shows the time that the machine has waited for board unloading on the most downstream stage. Note that when the
machine is mounting components or the upstream machine is standing by for supply, the delay time will not be counted
even if the board is standing by for unloading. The average unloading delay time per board or the cumulative unloading
delay time can be displayed by pressing the [Unit Change] button.
• Finished (boards)
Shows the quantity of finished boards.
• Max. Output
• board/h
This is the number of boards that can be produced in an hour. This is calculated in reverse from the average mounting
time and average transfer time. Note that the board supply delay time and error stop time are not included.
• block/h
This is the number of blocks that can be produced in an hour. This is calculated in reverse from the average mounting
time and number of blocks per board in the board information.
• chip/h
This is the number of chips that can be produced in an hour. This is calculated in reverse from the "Cycle Time (sec/
chip)" displayed on the [Main] tab screen.
• [Reset] button
Resets the production control information, including the various data, current production quantity, current unloader
quantity, scheduled production quantity and scheduled unloader quantity displayed on the screen. The "Board Counter"
value on the Setup screen is also reset when this production data is reset.
