Masking material Good coverage

Recognition time Depends on the method: 20 ms - 200ms

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 DX4 is designed

for placement of 01005 com-

ponents (0.4 mm x 0.2 mm).

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

DX4. 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 perfor-

mance loss, with minimum

pitch and irrespective of the

larger components which are

next to the 01005 --compo-

nent. This equates to true

01005 capability. As a rule

with 01005 placement, a

finely tuned overall 01005

process is the basic require-

ment 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 DX4, provided the rel-

evant underlying conditions are fulfilled:

Machine type SIPLACE DX4

Placement head SpeedStar with component camera

type 23

Nozzle type 1005

Feeder module type 2x8mm SIPLACE X feeder module

Station software 706.01 or later

SIPLACE Pro 10.0 or later

Machine Maintenance

We recommend that you

have your SIPLACE DX4

serviced on a regular basis to

keep it in prime condition

during productive use. The

SIPLACE DX4 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 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

maintenance work. This

requires no special training

and can be performed by the

line operators, with the help

of the maintenance guide.

Weekly maintenance of one

DX4 line takes a maximum of

1 hour, an optimum proce-

dure can be much faster.

3 monthly and 6 monthly

maintenance tasks

The 3 monthly and 6 monthly

maintenance tasks are a

combination of simple and

more complex major jobs.

We recommend that you

train your operating or ser-

vice personnel before per-

forming these more complex

tasks.

The 3 monthly and 6 monthly

maintenance can usually be

performed when the solder-

ing furnace for the line is ser-

viced.
