1.19 Block Skip

A single board can be divided into many smaller boards or blocks. This is called a multi-

block board. If some of the blocks on a multi-block board are defective, those blocks

must be skipped to avoid placing parts there.

1.19.1 Block Skip Method

The three methods of setting the block skip function are described below.

• Using the Skip function in N_data of program. This is effective for skipping specific

blocks in a large lot.

Note: For further information, refer to the MCS/2H System Operation Manual or F4G User’s

Manual.

• Using the [SKIP] command function on the machine.

This is effective for skipping specific blocks in a small lot.

Note: For further information refer to Section 1.19.2 (1) “Using Machine Commands” of this

chapter.

• Using the machine fiducial camera to read block skip marks. This is good for random

block skips.

Note: For more information on reading block skip marks with the fiducial camera, refer to

Section 1.19.2 (2) “Setting Automatic Block Skip Marks” of this chapter.

For further information, refer to the MCS/2H System Operation Manual or F4G User’s

Manual.

1.19.2 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.

(1) Using Machine Commands

1. Using the host computer Skip function in N_data, create a multi-block program and

transmit it to the machine.

Note: For further information, refer to the MCS/2H System Operation Manual or F4G User’s

Manual.

2. Select the transmitted program as the production program.

3. Press the [PROGRAM], [SKIP] and [BLOCK] command function keys.

The display will change to the one shown below. 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.

[Example]

The display will change accordingly. If 3 is entered “B 3P (green)” will change to “B

3S (yellow).”

Note: Refer to Chapter 3 “Command Descriptions” in Part 3 “Commands” for further details.

5. A block skip displayed in red indicates that the block has been set at the host

computer and cannot be changed on the machine.

6. Enter the block skip number (the block number displayed in yellow) one more time to

cancel the block skip flag.

[Example]

The display will change accordingly. If 3 is entered “B 3S (yellow)” will change to “B

3P (green).”

7. 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 program and cannot

be canceled at the machine.
