Description

In the cluster technology

each subpanel is assigned

an inkspot. If this is present

during the measurement via

the PCB vision module, the

corresponding subpanel is

populated. This function

helps prevent unnecessary

costs caused by placement

of defective panels.

01005 Placement

In its standard version, the

SIPLACE SX is designed for

placement of 01005 compo-

nents (0.4 mm x 0.2 mm).

The following placement

variants are available:

• SpeedStar

• MultiStar with component

camera type 30

The SIPLACE component

library already contains the

contours and dimensions of

01005 components. Spe-

cially developed component

nozzles of type 1005 are also

available for the SIPLACE

SX. These are adjusted to

the shape and size of the

01005 components and have

- as with all other SIPLACE

nozzles - a highly wear-proof

ceramic tip and flexible noz-

zle seat. This guarantees

maximum precision and pro-

cess reliability. Optimized

pickup is guaranteed by the

ideal feeding conditions in

the SIPLACE X feeder mod-

ule. The smaller the ele-

ments to be picked up, the

more accurate the pickup

needs to be.

Pickup is performed contact-

free to compensate minor

inaccuracies e.g. from com-

ponent or pocket tolerances

and to prevent mechanical

damage to the components.

The design of the SIPLACE

X feeder modules takes this

problem into account: new

motors and the reduced use

of fine mechanics help. Small

components can be placed

without performance loss,

with minimum pitch and irre-

spective of the larger compo-

nents which are next to the

01005 component. This

equates to true 01005 capa-

bility. As a rule with 01005

placement, a finely tuned

overall 01005 process is the

basic requirement if you want

to achieve excellent results.

All the process parameters

must be optimized. The

SIPLACE team will be

pleased to advise you on

how to do this.

01005 measurement

results and ambient condi-

tions

As the dpm values and

pickup rates for 01005 place-

ment depend greatly on the

respective measuring condi-

tions, it is not advisable to

specify these without consid-

ering the corresponding

ambient conditions.

The following table shows typical values for 01005 placement,

which can be achieved with a SIPLACE SX, provided the rel-

evant underlying conditions are fulfilled:

Machine Maintenance

We recommend that you

have your SIPLACE SX ser-

viced on a regular basis to

keep it in prime condition

during productive use. The

SIPLACE SX Maintenance

Guide contains recommen-

dations for the maintenance

intervals. All maintenance

tasks are explained in detail

with clear diagrams.

The maintenance intervals

are weekly, 3 monthly (only

when the SIPLACE SX is

configured with a C&P20

head) and 6 monthly.

For simpler organization of

line maintenance during daily

production operations, the

degree of complexity is spec-

ified for each maintenance

task. These levels are minor

and major maintenance.

Weekly maintenance tasks

The weekly maintenance

tasks are simple, minor work

only. This requires no special

training and can be per-

formed by the line operators,

with the help of the mainte-

nance guide.

Weekly maintenance of one

SIPLACE SX line takes a

maximum of 1 hour, an opti-

mum procedure can be much

faster.

3 monthly and 6 monthly

maintenance tasks

The 3 monthly (only when

the SIPLACE SX is config-

ured with a C&P20 head)

and 6 monthly maintenance

tasks are a combination of

simple and more complex

major work. We recommend

that you train your operating

or service personnel before

performing these more com-

plex tasks.

The 3 monthly and 6 monthly

maintenance can usually be

performed when the solder-

ing furnace for the line is ser-

viced
