P .C.B. Positioning (Placement Coordinate Reference) P .C.B. Stopper P1 descends and the P .C.B. which has moved to the P .C.B. positioning section from the standby position makes a U-turn just before it reaches P .C.B. …
3. Surface Mounting Mechanism
The following briefly describes how components are mounted on P.C.B.’s.
(a) The explanation is based on the P.C.B. flow diretion "From
Left to Right (L Æ R)" and the P.C.B. positioning reference
"Rear Left" (L-BACK).
(b) Refer to "1. Scope of Actions" in "Section 2" of "Vol. 2: Op-
eration (Supervisor)" for details.
3.1 P.C.B. Transfer and Positioning
P.C.B. Transfer (from the input machine)
The P.C.B. transferred from the input machine is carried by the L
conveyor and is stopped at the standby position by P.C.B. Stopper
P1.

P.C.B. Positioning (PRI PCB STR)
P.C.B. Stopper P1 descends and the P.C.B. which has moved to
the P.C.B. positioning section from the standby position is stopped
by P.C.B. Stopper P2.
The P.C.B. is held firmly by the clamping plate on the P.C.B. posi-
tioning section.

P.C.B. Positioning (Placement Coordinate Reference)
P.C.B. Stopper P1 descends and the P.C.B. which has moved to
the P.C.B. positioning section from the standby position makes a
U-turn just before it reaches P.C.B. Stopper P2 and is stopped by
P.C.B. Stopper P1 that has already ascended.
The P.C.B. is held firmly by the clamping plate on the P.C.B. posi-
tioning section.

3.2 Component Picks and Placement
Component Picks
Components are picked up from the feeder by the vacuum nozzles
on the placement heads.

Component Placement
The components picked up by the vacuum nozzles are placed on
the P.C.B. (standby mode) in the P.C.B. positioning section.
