(a) When P.C.B.’s are positioned on the P.C.B. positioning sec-

tion and mechanical accuracy in P.C.B. positioning varies

due to variation in outer dimensions of P.C.B.’s, the P.E.C.

recognition function can work effectively to reduce such

inaccuracy.

(b) Fiducial marks are put to detect the position of placement

patterns. Therefore, the positional relation between fidu-

cial marks and placement patterns must be constant. Oth-

erwise, the placement accuracy cannot be improved.

2.4 P.E.C. Recognition Function

Note

2.5 Automatic Feeder Axis Adjustment Function

When a component is picked up by the nozzle and shifted from the

correct pick-up position, this function uses the recognition system to

correct the deviation for accurate component placement.

By feeding the recognized amount of correction back to the pick-up po-

sition, the pick-up position can also be brought close to the specified

one.

2.6 Conveyor Width Automatic Adjustment Function

When the current program is changed, the conveyor width is automati-

2.7 File Operation

The placement data can be saved on a 3.5-inch floppy disk in the FD

(floppy disk drive) of the front service panel or can be loaded from the

floppy disk.

• The data stored on the hard disk (HD) of the main machine can be

saved on a floppy disk (FD).

A created file can be loaded, using the network terminal (option).

• The data stored on a floppy disk (FD) can be loaded to the main

machine side.

A file of the pattern program data created on the network terminal

(option) can be loaded to the machine side. (Excl. the component

library data)

• The pattern program data on a floppy disk (FD) can be deleted.

2.8 Simultaneous Pick-Up Function

When two heads pick up the components from the corresponding feed-

ers, both heads descend and pick up the components simultaneously,

shortening the cycle time.

2.9 Pick-Up Priority Function

This function is based on the idea that the beams can be operated effi-

ciently if two heads (right and left heads) can pick up components at the

same time and follow the component placement sequence.

By pairing two steps of placement data (setting "2" in the "S" text box of

the placement data), each component can automatically be placed effi-

ciently in the order of the specified placement steps through the se-

quence "Pick Æ Pick Æ Recognition Æ Recognition Æ Place Æ Place".

The automatic feeder axis adjustment mode becomes valid for both

right and left heads when components are picked up.
