Items Specifications

PCB conditions Warpage: Max. 2.0 mm

If downward PCB warpage occurs when the PCB is clamped, please use back-up

pins or a back-up plate to support the underside of the PCB.

Premounted part height: Differs depending on the head types (refer to “3.4 Head

Specifications”).

Premounted part height on lower surface: Max. 25.4 mm.

• No premounted parts possible in the shaded areas.

• 3 mm of dead space on both edges of the PCB is required for clamping.

• Contact Fuji if the PCB warpage is lower than the conveyance surface.

• It is necessary that 50% of the contact surface on the underside of the panel

indicated above be touching the conveyor surface. Furthermore, contact Fuji if

there are notches at both sides of the PCB and the PCB warpage is lower than

the conveyance surface.

< Without back-up pins>

* Without back-up pins: Max =

50.8mm.

4. Machine Structure

Many parts of the NXT (bases, modules, heads, nozzle stations, device units,

etc.) can be freely configured.

4.1. Machine Base

The base is the foundation upon which the modules are mounted. Bases are

available in two sizes (2MII-base and 4MII-base), depending on the line

configuration.

4.2. Modules

Each module comprises of an XY-robot, head, PCB conveyor, PCB clamper,

device unit, and vision system cameras.

Three sizes of modules are available: a 325 (W) mm M3II module, and a 650 (W)

mm M6II, M6IISP module. A module change unit is available, allowing the line to

be reconfigured easily by the user.

4.3. Heads

Depending on the parts being handled, eight different, easily exchangeable head

types are available: H12HS [H12] (12 nozzles), H08 (8 nozzles), H04 (4 nozzles),

H02 (2 nozzles), H01 (1 nozzle), G04 (4 nozzles, high accuracy placement), OF

(Supports insertion placement), and GL (Glue application).

4.4. Main Conveyor

The NXTII PCB conveyance system provides shock-free transport of the PCB,

with a motor driven, conveyor width adjustment function, and simple PCB flow

direction change capabilities.

The double conveyor not only conveys and produces the same PCB, but can

also be used to convey and produce PCBs of different widths, and the conveyor

widths can be changed independently. Replace the back-up plates based on the

size of the PCB being produced.

Notes:

1. Lane 1 back-up plate for double conveyor.

2. Lane 2 back-up plate for double conveyor.

3. When using this back-up plate, the rear conveyor is adjusted to a position further forward from the standard

position (PCB width: 280 mm). As a result, when producing PCBs on the rear conveyor, the Y-axis

movement distance is shorter when compared with the movement distance when the rear conveyor is at its

standard position, therefore resulting in a faster cycle time.

4. Backup plate for single conveyor.
