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.

Smart Pin Support

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.

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.

Component feeding

Component trolley X

The X component trolleys

are independent and easily

maneuverable modules. The

tape reels are taken up into

the tape container of the X

component trolley. A cutting

device on the machine auto-

matically cuts up the used

tape material. The X compo-

nent trolleys can be set up

directly on the machine or at

an external setup area with

feeder modules. The benefits

of offline setup are that the

configurations can be pre-

pared without stopping the

line. This allows the setup to

be changed very quickly

using the changeover table

principle. The SIPLACE X

component trolleys also sup-

port fast setting up and tear-

ing down of feeder modules

even during the placement

process.

The component feeders are

at rest during the placement

process - allowing tapes to

be spliced without stopping

the machine. With the help of

an optional component bar-

code reader and the Setup

Center option, the barcodes

on the tape reels can be read

and checked.

This ensures the correct

assignment of components

to tracks and the traceability

of PCB placement with the

Traceability software.

For safety reasons, unoccu-

pied locations are fitted with

so-called dummy feeder

modules.
