For the Flexible Production with High Throughput

SEHO PowerSelective is featured with an outstanding

modular machine construction that ensures highest flexibility.

The basic system can ideally be configurated to meet different

specific production requirements and provides the possibility

to be upgraded step by step at any later date to suit sub-

sequent production developments.

The PowerSelective may be equipped with several soldering

units. Thus, miniwave soldering processes and multiwave

soldering processes, even conventional wave soldering, can

be covered with only one machine.

Flexibility is also given in the handling of the assemblies.

Both, bare boards as well as assemblies in carriers can be

processed with the PowerSelective.

All selective soldering systems from SEHO feature a compre-

hensive hardware and software package to automatically

monitor and control the entire process 100 %.

Highest flexibility at high production volumes, maximum

soldering quality and process reliability sum up to one

result: SEHO PowerSelective.

Made in Germany:

Precision in Manufacturing = Quality Results

The highly precise portal axis system with a repeatability of

± 0.1 mm ensures the accurate and reliable positioning of the

assemblies at the different work stations.

The gripper system is mounted at the z axis. After the fluxing

and preheating process, the gripper takes the assembly from

the conveyor system, positiones it precisely at the soldering

units and finally deposits the printed circuit board back onto

the transport system. Depending upon requirement, there are

different grippers available which can be used for handling of

carriers, or direct gripper systems that are designed for the

handling of bare boards. If needed the grippers may be

equipped with additional functions, such as fixation of com-

ponents

The gripper is provided with a rotating function up to 270° and

may be tilted up to 12° to obtain an ideal solder angle even

when processing demanding assemblies.

Precise to the Point:

The Fluxer Area

The PowerSelective is equipped with a micro drop

jet fluxer unit which may either be integrated in the

inlet conveyor of the machine or in a separate fluxer

module in front of the PowerSelective, depending

on your requirements. This ensures lowest cycle

times. The micro drop jet fluxer targets the flux to

the exact point and avoids wetting of surrounding

areas.

Several nozzle heads may be installed. Each

nozzle head thereby can be equipped with up to

three micro drop jet nozzles to further reduce cycle

times.

The function of the fluxer nozzle can be monitored

by means of a capacitive sensor.

Maximum process reliability without any influence

on the cycle time is given with the flux quantity

monitoring system, winner of the NPI award. This

unique high precision fluxer control system

monitors the flux quantity that actually leaves the

nozzle during the fluxing process. Any deviation

from the pre-set value is immediately detected.

Maximum Flexibility in Your Production

Ensures Defined Temperature Profiles: The Preheat Area

The preheat area of the PowerSelective also presents itself

very flexible.

Depending on your production requirements several quartz

heater cassettes or convection preheat units may be installed

either at the inlet conveyor of the PowerSelective or in exter-

nal preheater modules. For printed circuit boards requiring

high heat energy, top side heatings are available as well.

Individually programmable quartz heater elements and board

surface temperature control by pyrometer ensure a precise,

gradient-controlled preheat process.

High Precision - Maximum Quality: The Soldering Area

The state-of-the-art solder nozzle technology developed by

SEHO ensures maximum precision in the soldering area.

Depending on your manufacturing requirements, up to two

soldering units may be integrated into the PowerSelective,

which are designed for miniwave soldering processes, multi-

wave soldering or even conventional wave soldering.

For electronic manufacturings with high volume and low mix

production, product-specific multi-nozzle tools ensure short

cycle times as all joints are soldered simultaneously.

The SEHO solder nozzle design guarantees optimum energy

transfer. Thus, perfect hole fill is achieved, even when pro-

cessing high mass assemblies and demanding board layouts.

Due to the special nozzle tool design, formation of solder

bridges and solder balls is reduced remarkably.

For productions with a wide range of assemblies, miniwave

solder nozzles guarantee highest flexibility.

Alternatively, there are two different solder nozzle types avail-

able. Non-wetted solder nozzles are nearly maintenance-free

and they are featured with an

almost unlimited lifetime. Wetted

solder nozzles stand out due to

the possibility that even ex-

tremely small pitches can be

processed without any difficul-

ties.

Of course, both the product-specific multi-nozzle tools as well

as the various miniwave solder nozzles are quickly ex-

changeable.

Change of nozzles or maintenance works can be made „on-

the-fly“ thus reducing production downtimes to zero.

Permanent touchless wave height control systems and

monitoring systems for automatic tool measurement guaran-

tee precise and consistent process conditions, without having

any influence on the cycle time.

Innovative: Integrated Additional Processes

The PowerSelective provides plenty of room for your indivi-

dual production requirements on smallest footprint.

This also includes integrated additional processes such as a

cooling area. In addition, a selective brush system can be

integrated to remove any flux and solder residues, or solder

balls immediately after the soldering process.

Moreover, the PowerSelective allows integration of the SEHO

PowerVision AOI system to detect potential soldering defects

automatically, such as insufficient wetting, missing pins or

solder bridges.

The benefits are quite obvious: absolutely safe processes

and reduction of your manufacturing costs.

Technical Data and Options

Unique: 100 % Process Control

The PowerSelective provides state-of-the-art control

technology, with sensors and software tools that continuously

monitor all process steps:

From automatic tool measurement and position correction

with fiducial recognition, to flux quantity monitoring and

reproducible temperature profiles in the preheat area as well

as the permanent and touchless wave height control.

Moreover, the comprehensive package includes an

automatic solder level control, a nozzle coding system with

intelligent tool management as well as process visualization

and solder joint inspection with an integrated AOI system.

With the machine communication software mcServer,

selective soldering processes are made transparent and can

be traced completely. The mcServer software tool collects,

analyzes and archieves all information about the machine and

production process systematically.

Teaching of solder joints is particularly easy with the

PowerSelective, and of course can be made offline in case of a

wide range of assemblies. Basic data are taken from a picture of

the printed circuit board, gerber data or DXF files. The wizard

comfortably takes the user step by step through the software.

Likewise uncomplicated is the programming process for an

integrated AOI system: The inspection areas are already pre-

defined from the soldering program and a comprehensive

component library with standard values that can be adapted any

time, simplifies programming of the AOI tremendously.
