Patented by SEHO: Ultrasonic Cleaning of Nozzles

Soiled solder nozzles remarkably

affect the reproducibility of soldering

processes.

With the ultrasonic cleaning unit from

SEHO, the liquid solder is set into

oscillation which thereby cleans the

surface of the nozzle. Using the

existing inert atmosphere, the nozzle

surface is immediately re-wetted:

The solder nozzle is restored

to its original state!

n effectively dissolves residues from the solder nozzle

and ensures a new and complete wetting

n maximum process reliability

n remarkably longer lifetime of the solder nozzles,

up to several months

n programmable cleaning cycles

n significantly reduced maintenance requirements

and higher machine availability

n gentle cleaning:

- no chemical substances

- no health hazardous vapors

- no follow-up costs for consumables

- no mechanical tools

n convection, quartz, pulsar and infrared

emitters in the preheat area

n Twin-Select:

dual solder pot system with separate

z axes

n SYNCHRO mode guarantees

maximum production volumes

n automatic ultrasonic cleaning

of wetted solder nozzles ensures

highest machine availability

n automatic selective brush station

n SEHO AOI easy to be integrated

n 100 % process control

n modular concept:

system modules can be combined indi-

vidually and can freely be configurated

with fluxer, preheatings, soldering units,

cooling module, selective brush system

and AOI, extendable any time

n up to 6 soldering units and more

than 15 parallel workstations in

one system

Fluxing Process with Maximum Precision

Selective soldering systems from SEHO are equipped with a

micro drop jet fluxer that particularly focusses on two points:

Maximum precision and minimum flux consumption.

Several nozzle heads that ensure a defined flux application in

smallest areas can be installed on the high precision xy axis

system.

Thus, throughput can be increased remarkably when proces-

sing symmetric panels. As an alternative, two different flux

types can be used simultaneously, controlled via the software.

Each of the nozzle heads may carry several drop jet nozzles.

This allows to flux multi-row connectors with only one passage.

Flexible Preheat Process

The preheat area of the SelectLine can be configured individu-

ally in length and type. In particular it scores high because of its

energy efficiency.

Individually programmable and controllable quartz heaters or

pulsar heating elements ensure an effective heat transfer to the

PCB bottom side and guarantee very homogeneous heating

even in case of different thermal mass. A touchless pyrometer

can be installed to precisely control the preheat temperature

profile and to allow gradient-controlled heating of the assem-

blies.

If needed, a top side heating can be installed additionally.

Controlled via the software, both preheating systems are

perfectly matched to guarantee reproducible temperature

profiles.

In case of processing high mass assemblies, a convection

module ensures perfect and effective heat transfer with homo-

geneous temperature distribution within the preheat zone.

To constantly keep assemblies on the same temperature level

during long soldering cycles, a top side heating may also be

integrated in the soldering area.

The PLUS of Flexibility and Precision

Time plays a key role in modern electronic production.

With the SelectLine platform, SEHO developed a selective

soldering system that features a revolutionary design. The

SelectLine convinces with highest precision and solder joint

quality as well as a high degree of flexibility: No change-over

is required to dynamically process a variety of assemblies

with short cycle times.

The SelectLine machine concept is consistently modular

thus ensuring clear cost benefits. Several modules with

different dimensions can individually be configurated with

fluxer, preheatings, soldering units, cooling modules,

selective brush system and AOI and, depending on your

requirements, they may be combined to a complete

manufacturing line. Even if the basic configuration should be

designed for stand-alone operation it may be expanded with

additional modules at any time to be used inline.

Absolutely unique is the 100 % process control that is

provided by all selective soldering systems from SEHO.
