4.1 Movement of machine
4.1.1 Transfer method and mount method
In this function, the partition mount is executed in the following procedures.
(1) A board is transferred to the main stopper; the board is fixed; and parts of first half area
are mounted.
(2) After parts of first half area are mounted, the board is released and transferred to the
exit stopper.
(3) After the board reaches the exit stopper, the board is fixed, and parts of second half
area are mounted.
(4) After parts of second half area are mounted, the board is released and transferred to
the lower machine.
(5) After the board is transferred to the lower machine, a next board is transferred from
entrance.

* The next board is not carried in until the mounted board is carried out. When you insert a
board by manual, insert it when no board exists in the machine. If a board is inserted during
transfer, the board might be regarded as a part of transferring board and be overlapped.
4.1.2 Decision method of mount position for each mount
The mount position (“first half mount” or “second half mount”) of each mount data is
decided as follows.
Optimized or
unoptimized board data
Decision method of mount position (“first half mount” or
“second half mount”)
Optimized board data The mount position of each mount data is decided by
optimization.
Unoptimized board data Basically, the mount position of each mount data is uniformly
decided from the mount coordinates.
That is to say, all mount data that can be mounted at “first half
mount” are mounted at “first half mount” and the others are
mounted at “second half mount”.
But, when the local fiducial or the local bad mark is not
recognizable at “first half mount” even if the mount coordinate of
mount data can be mounted at “first half mount”, this mount is
mounted at “second half mount”.
4.1.3 Existence of “first half mount” parts and “second half mount” parts
and the movement
Existence of “first half mount” parts and “second half mount” parts and these movements
are as follows.
Board data type Movement
Both “first half mount” parts
and “second half mount” parts
exists
Both “first half mount” and “second half mount” are
executed.
There are restrictions of board data to be described below.
Only second half mount parts
exists
(Long boards which do not
have “first half mount” parts)
Only “second half mount” is executed. When it is necessary,
bad marks are recognized at the main stopper position.
There are restrictions of board data to be described below.
Only first half mount parts
exists
(Short boards)
Only “first half mount” is executed. Board is not fixed at the
exit stopper position.
There are no restrictions of board data to be described
below. (For example, board fiducial for “second half mount”
is not necessary, and values other than “0.000” can be set
to X coordinate of block offset)
4.2 Cautions when creating board data
There are following restrictions when creating board data for “long board partition mount”.
But, there are no following restrictions on board data that do not need the partition mount
(only “first half mount” exists).
4.2.1 Mount coordinate
Input the coordinates from block origin to mount coordinates. It is not necessary to
distinguish “first half mount” from “second half mount”.
4.2.2 Block offset
Values of X coordinate and R coordinate of block offset have to be “0.000”. When board
data that value of X coordinate or R coordinate is not “0.000” (X positions of same mount
point of each block are different in each block), execute block distribution by the board
editor.
Values other than “0.000” can also be set to Y coordinate.
Example 1: Usable board data without block distribution (Only Y coordinate of block offset is
set)
