Description

In the cluster technology

each subpanel is assigned an

ink spot. If this is present dur-

ing the measurement via the

PCB vision module, the corre-

sponding subpanel is popu-

lated.

It is also possible to accom-

plish the population of the

subpanel when the ink spot is

missing. With this function it

is possible to eliminate costs

due to unnecessary popula-

tion of faulty subpanels.

Global Ink Spot

Each GOOD/SCRAP scan takes

some time, and the time re-

quired is even greater if there

are a large number of sub-

panels on a PCB. Using the

global ink spot can result in a

significant reduction of these

secondary times.

The PCB vision module

searches at positions taught

before for the defined fidu-

cial. In case of recognition

there is no following evalua-

tion of subpanels. The sys-

tem allows the operator to

choose also the reverse inter-

pretation.

Recognition of the position

of the feeder modules

The pick-up position of the

components can be deter-

mined precisely with the aid

of the position recognition

for the feeder. The offset in

position relative to the stored

ideal position is determined

on the basis of fiducials on

the feeder modules using the

PCB vision module. This pro-

vides very high pick-up reli-

ability even for the very first

component, which is particu-

larly important for small com-

ponents.

Sample Configuration

Services

As a service, SIEMENS A&D

EA can fully integrate the

SIPLACE D3 placement

machine into your produc-

tion line. With our extensive

expertise and by using the

right tools and equipment,

we can ensure that the instal-

lation process runs smoothly

and efficiently. However, this

will require you to clarify the

infrastructure aspects in ad-

vance and make any neces-

sary changes at your

production facility.

Safety instructions

Read the operating instruc-

tions before starting to set up

and commission the place-

ment machine. The applica-

ble accident prevention

regulations concerning the

transportation of heavy

goods must be followed.
