PCB warpage

PCB warpage during placement

PCB warpage downwards max. 0.5 mm

Use the magnetic pin supports, to achieve

this value.

When there is warpage under 2 mm, the

inkspots in the center of the board are also

within the focus of the digital camera. When

all the tolerances are taken into account,

this value is reduced to 1.5 mm.

You should also note that the warpage

reduces the component height.

General

Wide boards tend to deflect

during placement such that,

under certain circumstances,

the components can no lon-

ger be placed with the

desired accuracy. Highly

curved PCBs also affect the

placement accuracy. This

problem can be easily recti-

fied by fitting support pins on

the lifting table. The use of

Smart Pin Support enables

you to reduce the number of

feeder locations by a maxi-

mum of 6 locations. It may

also be necessary to use

double setup of components.

This is undertaken automati-

cally by the programming

system.

Smart Pin Support

The support pins are auto-

matically placed on the lifting

table with the help of the

Smart Pin Support option.

A gripper unit is used to pick

the support pins up from spe-

cial magazines and place

them in the prescribed posi-

tions.

Before a Smart Support pin

is placed, the position is

cleaned of any contaminants

with a gentle blast of air. In

addition, the correct position-

ing of the support pin is

checked after its placement,

with the PCB camera.

Magazine

There are two different mag-

azines available for auto-

matic changeover of max. 5

or max. 10 support pins in the

various machine configura-

tions. These magazines are

fixed to a magazine holder

and are fitted to the COT

insert.

Programming

The positions of the support

pins in the machine can be

defined for each board side,

in the SIPLACE Pro Board

Editor.

A 3D image of the board and

the support pins allows you

to recognize and prevent any

collision risks between the

support pin and the compo-

nents, even for stepped

transportation of boards with

excess length.

Double setup of components

may be necessary in the

SIPLACE X-Series S,

depending on the board

design and line layout.

SIPLACE Pro takes this into

account automatically.

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 to be

changed very quickly, using

the changeover table princi-

ple, 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.
