Edition 2.0E - 17 - NXT II Specifications

3.6. PCBs

Items Specifications

M3II, M6II

Min. 48(L) x 48(W) ~ Max. 534(L) x 510(W) (Using double conveyor)

Min. 48(L) x 48(W) ~ Max. 534(L) x 610(W) (Using single conveyor)

M6IISP

Min. 48(L) x 48(W) ~ Max. 520(L) x 510(W) (Using double conveyor)

Min. 48(L) x 48(W) ~ Max. 520(L) x 610(W) (Using single conveyor)

Thickness: 0.4 ~ 6 mm (Consult Fuji regarding the use of PCBs with thickness

less than 0.4 mm)

PCB size

Notes:

1. Double conveyors can handle PCBs up to 280(W) mm. PCBs larger than

280(W) mm must be produced by changing the double conveyor to single lane

production mode.

2. PCBs with 0.3 ~ 0.4 mm in thickness are supported as an option.

3. When using PCBs larger than 250(L) mm on M3II modules, paired module

production is performed. (Refer to section 6.2)

Furthermore, the placement area on M3II modules extends up to 250(L) mm,

however, it is possible to convey PCBs up to 305(L) mm. In a situation such as

this, it is necessary to perform placement for the section lying outside the

250(L) mm area using an M6II, M6IISP module, or by performing M3II paired

module production. Fiducial marks must be within the range of 250(L) mm.

4. The following limitations apply to the panel size when using the G04 head.

M3II module: Max. 214(L) mm, M6II module: Max. 504(L) mm

M6IISP module: Max 490(L) mm

5. The G04 head is not supported for paired module production.

6. Consult with Fuji in advance regarding PCB support measures.

Materials

Glass-epoxy, composite, paper phenol, alumina, polyimide, etc.

(Please consult with Fuji regarding support for ceramic PCBs)

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.

Edition 2.0E - 19 - NXT II Specifications

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.
