3. Block Skip
A single board can be divided into many smaller boards or blocks. This is
called a multi-block board. On multi-block boards there may be cases when not
all blocks are free of defects. If there is a defective block on the board, this
block can be skipped by using the block skip function while the remaining
blocks continue to be produced.
How to use this function on the FCP IV-3 is explained in this chapter.
3.1 Block Skip Method
The three methods of setting the block skip function are described below.
• Using the Skip function in N_data of MCS/2H. This is effective for
skipping specific blocks in a large lot. For further information, refer to
the MCS/2H System Operation Manual.
• Using the [SKIP] command function on the machine. This is effective
for skipping specific blocks in a small lot. For further information
refer to Section 3.2.1.
• Using the machine fiducial camera to read block skip marks. This is
good for random block skips. For more information on reading block
skip marks with the fiducial camera, refer to Section 3.2.2 or to the
MCS/2H System Operation Manual.
3.2 Setting Block Skip
The block skip can be set at the operation panel on the machine. It can
also be set by programming a block skip mark on the appropriate part of
the board, which the camera will read to determine whether a block will
be skipped. Some simple examples are described below.
3.2.1 Using Machine Commands
(1) Using the MCS/2H Skip function in N_data, create a multi-
block program and transmit it to the FCP IV-3.
(2) Using the FCP IV-3 [PROGRAM] command (or with MCS/2H)
select the program transmitted in step (1) above.
(3) Press the [PROGRAM], [SKIP] and [BLOCK] command
function keys.
The display will change to the one shown on the next page. In
this display block 5 has been set to be skipped.

(4) Enter the block number you want to skip
using the numerical keypad (see figure at
right).
Press the number to be set as the block
number and then press the carriage return [CR] to enter the
value.
The display will change accordingly. If 3 is entered “B 3P
(green)” will change to “B 3S (yellow).”
Enter the block skip number one more time to cancel the block
skip flag.
(5) A block skip displayed in red indicates that the block has been
set at the MCS 30 and cannot be changed on the FCP IV-3.
(6) If the user presses the [RETURN] command function key after
all the block skips have been set, the previous screen will
display.
B 1P (green): Placing will be carried out on Block 1.
B 2S (yellow): Block 2 will be skipped. This skip was set at
the machine.
B 3S (red): Block 3 will be skipped. This skip was set in
the MCS/2H program and cannot be cancelled
at the machine.

3.2.2 Setting Automatic Block Skip Marks
In this case, the camera will read the block skip marks on the board
and automatically skip the appropriate blocks.
(1) Mark the board with very large bright (or dark) block skip
marks. Whether the mark is inside or outside each block makes
no difference. Only the number of the block is important.
(2) Enter the mark type, mark color (B/W) and CCD level in the
[Program] Mark_data via the MCS/2H editor, and enter the
mark sizes (Size X, Size Y) and reading threshold level (CCD).
(3) Enter every block number into sequence data (N_data) block
number (B).
(4) Enter the letter B into sequence data (N_data) device type (W).
(5) Enter the Mark_data Mark No. as the device number in
sequence data (N_data).
(6) Finally, enter the XY coordinates for each block skip mark into
sequence data (N_data).
The example below shows the entries for two block skip marks.
Program Data
Mark_data Type Ptn B/W CCD L/S Scan Size_a Size_b Size_c Size x Size_y

N_Data B W D X Y Q
001 1 B 001 -500 800 0.00 : Block skip mark 1
002 2 B 001 -1500 800 0.00 : Block skip mark 2
When B is entered in the W column, the machine will automatically
read the block skip marks and skip the boards that are marked
appropriately. Mark sizes (Size X, Size Y) and reading threshold
levels (CCD) can also be set at the machine. See Part 3, Section 3 of
this manual for further details.
