Panel lane and wafer lane conveyor

Wafer and panel level fan out process

Panel level fan out is used

for large workpiece carriers.

A double-sided thermal

release foil is attached to a

workpiece carrier (e.g. made

of steel or glass) and place-

ment is performed on this.

The panel level fan out

mode means that part of the

workpiece carrier is placed in

the first placement area and

the remaining part in the sec-

ond placement area. To

achieve the required accu-

racy, the fiducials on the

workpiece carrier are only

used for rough position rec-

ognition. These fiducials for

rough position searching

must be within an overlap-

ping area. Two fiducials are

enough. Four components

with fiducial structures are

then placed in this overlap-

ping area and measured for

fine position recognition pur-

poses. Other possible or

required fiducials are then

placed as references, in

addition to the fiducials

already placed. In the sec-

ond placement area, the four

fiducials already placed are

measured first, before pro-

ceeding as in the first place-

ment area.

Wafer level fan out is used

for smaller workpiece carri-

ers with different thick-

nesses.

The vacuum tooling used

can be temperature-con-

trolled.

The Wafer level fan out pro-

cess is available with Gas

station mode.

Wafer level fan out with

gas station mode

In Gas station mode, two

workpiece carriers moved

into the machine at the same

time. The first workpiece car-

rier is conveyed into the sec-

ond placement area, the

following workpiece carrier to

the first placement area.

These two workpiece carri-

ers are then clamped into

place at the same time.

This prevents the clamping

procedure from affecting the

accuracy of the other work-

piece carrier.

The two workpiece carriers

are placed parallel to one

another. One prerequisite for

Gas station mode, is that

the setup in the first and sec-

ond placement area is the

same.

Workpiece carrier warpage

Vacuum tooling

Workpiece carrier

The front and back edge of the workpiece carrier may not be

curved upwards. There is no guarantee that the curvature will be

pulled flat by the vacuum tooling.

Warpage across the direction of travel max.

1 % of the diagonal but not more than 0.1 mm.

The warpage is then pulled flat by the vacuum

tooling.

The side edges may not be curved downwards.

The side edges may not be curved upwards.

Component feeding

Component trolley X

The SIPLACE X component

trolleys are independent and

easily maneuverable mod-

ules. Four component trol-

leys, each with 40 tracks, can

be docked onto SIPLACE X

machines. The tape reels are

taken up into the tape con-

tainer of the component trol-

ley. A cutting device on the

machine automatically cuts

up the used tape material.

The component trolleys can

be set up directly on the

machine or at an external

setup area with feeder mod-

ules. The benefits of offline

setup are that the configura-

tions can be prepared with-

out stopping the line.

This allows the setup change

to be realized very quickly,

using the changeover table

principle, to rapidly change

the component trolleys.

The SIPLACE X component

trolleys also support fast set-

ting up and tearing down of

feeder modules even during

the placement process.

Tapes can be spliced without

stopping the machine.

For safety reasons, unoccu-

pied locations are fitted with

so-called dummy feeder

modules.
