1 . 2 Component Placement (starting with preparation for component picks) The X/Y beams are provided with placement heads that have nozzles on them. The nozzles pick up components and place them on the P .C.B.’s. Fig. 2B…
(3) The P.C.B. is clamped by the clamping plate and the pusher on the
P.C.B. positioning section.

The reference pin for positioning is aligned with the P.C.B. hole
position to position the P.C.B.’s.
The sequence is determined as follows.

P.C.B. Positioning Section:
P.E.C. Recognition (Recognition of Placement Position)
• The P.E.C. camera is used to detect through P.E.C. recognition if
the placed components are shifted from the correct position or not.
Note: This will be performed only when specified in the pattern
program.

Nozzle Stocker: Nozzle Change
• A vacuum nozzle is selected for components and the attached
nozzle is replaced with the proper one.
The vacuum nozzle on the placement head is stored in the nozzle
stocker and the required one is taken out of the stocker.
