3.1 Component pick-and-place head
3.1.1 Eight-in-line multi-head (FNC) assembly
The eight-in-line multi-head (FNC) assembly has 8 heads arranged in a row to pick up and mount components.
Head numbers are designated from 1 to 8, from the right as viewed from the front of the head assembly. The
spacing of adjacent nozzles attached to the head assembly is 16mm, which is identical to the pitch of the SS
feeder bank.
Heads 2, 4, 6 and 8 of the eight-in-line multi-head (FNC) assembly have a flying nozzle changer (FNC) to
change the nozzle while the head assembly is moving to a component feeder.

3.2 Nozzle types
To ensure stable component pickup, the correct nozzle that matches the component must be used. The
following sections explain typical nozzles which can be attached to each head.
3.2.1
Nozzles for the eight-in-line head assembly
On the eight-in-line multi-head (FNC) assembly, 6 types of nozzles (Type A) can be chosen and attached to
Heads 1, 3, 5 or 7 while FNC nozzles (Type F) can be attached to Heads 2, 4. 6 and 8. On the eight-in-line
multi-head (SF) assembly, 6 types of nozzles (Type A) can be chosen and attached to the mating heads (manual
nozzle change).

Type A nozzles
Type A nozzles (301A, 302A, 303A, 304A, 305A and 306A) can be attached to all heads of eight-in-line SF multi-head
assemblies or to Heads 1, 3, 5 and 7 of eight-in-line FNC multi-head assemblies.
Type 305A nozzle cannot be attached to eight-in-line FNC multi-head assemblies.
Type F nozzles
The eight-in-line FNC multi-head assemblies have a flying nozzle changer (FNC) at the tip of Heads 2, 4, 6 and 8. Three
types of nozzles (Types 301F, 302F, and 303F) can be attached to each FNC head.
