Efcient integration of device connectivity in the SMT process
With advanced products
Increasing requirements such as the demand for miniaturisation, higher functional
densities of modules and cost-effective manufacturing processes have led to
changes to PCB assembly processes. SMT (surface-mount technology) is thus
increasingly used in practice instead of the conventional through-hole technology
(THT). The SMT process has now established itself as the accepted standard in the
manufacture of electronic components.
The connection system can be integrated in the SMT process in two ways: by
means of THR (through-hole reow) or SMD (surface-mount device) technology.
Acombination of the two approaches is also possible.

As a leading supplier and pioneer of device connection technology, Weidmüller
offers the broadest range of products that is available for the SMT process. With
our THR and SMD connection components, we support highly efcient electronic
device manufacturing. Our connection elements are handled fully automatically
together with the component assembly in a single manufacturing process, which
reduces your manufacturing costs. In addition, we assist you throughout the
design-in process with products, in-depth knowledge of applications and proven
solutions expertise.
You will nd a detailed description
of the integration of OMNIMATE
device connection technology in the
SMT process in our White Paper –

THR components SMD components
In the through-hole reow process (THR), components
are inserted through a hole in the PCB and then soldered
to other SMT components. The special challenge of this
method is that the components need to withstand the
high temperatures of the SMT process.
In the SMT process, the surface-mounted devices (SMDs)
are soldered to the PCB with solder pads. The use of
SMD components means that it is possible to dispense
with wire pins to the components and with the holes
normally required for attachment to the PCB.
