Weidmüller is a leading international provider of solutions for electrical connectivity,transmission and conditioning of power, signal and data in industrial environments.The company with headquarters in Detmold/Germany develops, produces and sellsproducts in the field of electrical connectivity and electronics all over the world.
Additionally, collisions between the
components and the PCB can completely avoided.14

SMT design-in recommendations
In addition, most normal one layer stencils for fine pitch
techniques and the standard process parameters for squeegee
speed and printing can used. Outstanding
advantages are offered the short pins the SL-SMT and
the optimising the travel height well the precision the
pin end position.
Assembly short pins great performance
Due the shorter pins 1.W.
Our specially designed SL-SMT male headers allow optical
inspection the primary side PCB even for varieties with
180° outlet direction.
Quality control control better
To determine the quality the solder joints the THR
components with short long pins, Weidmüller has chosen the
quick and simple checking using optical inspection, X-ray
examination.
Reflow solder the material the future
High temperature resistant, halogen free insulating material LCP
(Liquid Crystal Polymer) has melting point 335°C. not
only has high dimensional stability, but also good resistance to
the heat soldering. the
same time, the SMT optimised male headers from Weidmüller
increase the assembly strength due their low weight. This meets the requirements the internationally
recognised norms and standards. Standard
and anti-static packaging also allows fully automatic assembly
with the commonly available Pick Place systems.
. This also supported
on the one side the fact that SL-SMT male headers have a
low profile, and also the reduced packaging height.
Unbeatable advantage: the paste pushed out the
placement hole during the placement process.5 mm, you can have higher
packing volume for tape reel tray. This meets the requirements for
in-process quality control. Our SL-SMT male headers made from
LCP are future proof, and can used lead-free solder
processes. This leads to, another key advantage LCP:
though its low thermal expansion coefficient, the bending
an assembly following the soldering process avoided
