Large batch sizes – frequent product changes?
We will nd the best system for you!
Requirements in the eld of reow soldering are as varied as the products produced on an SMD pro-
duction line. That is why we provide you with intensive guidance before the purchase decision as to
which system is the most efcient for the applications you require.
We take all relevant parameters into consideration in the process of this. Take for example the through-
put rate, this is one of the most important parameters for determining the optimum process zone length.
If frequent product changes and multi-shift operation are added to the equation, additional options will
be required that need also be taken into account. After clarifying all the process-relevant parameters,
you can rest assured that you will have a reow soldering system adapted to all your needs, one with
which you can manufacture reliably and efciently. The diverse range of options within the VisionX range
means that we have the right system for every manufacturing environment and for a perfect solder result.

Reliable from A to B
with exible transport systems
Your component will run through various sections of the system during the sol-
dering process: from the preheating zone, through the peak zone to the cooling
zone. Secure transportation is a key entity when it comes to continuous pro-
cesses. Rehm offers exible systems for this.
Our transport systems provide the perfect t for your components regardless of
the circuit board geometry. Transport lanes and speeds are variably adjustable
and enable parallel soldering processes with lead-free or leaded soldering in one
reow system. Depending on the product requirements, you can choose from
various transport models such as individual and double track transport, quadruple
or multi-track transport.
The optional centre support enables even the processing of large circuit boards or
boards with a exible base material with ease and prevents any sagging during the
reow soldering, thus guaranteeing a maximum degree of process stability.
