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.
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. Outstanding
advantages are offered the short pins the SL-SMT and
the optimising the travel height well the precision the
pin end position.W.5 mm, you can have higher
packing volume for tape reel tray.
Our specially designed SL-SMT male headers allow optical
inspection the primary side PCB even for varieties with
180° outlet direction. This leads to, another key advantage LCP:
though its low thermal expansion coefficient, the bending
an assembly following the soldering process avoided. Our SL-SMT male headers made from
LCP are future proof, and can used lead-free solder
processes. This meets the requirements the internationally
recognised norms and standards.
Assembly short pins great performance
Due the shorter pins 1. 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. This meets the requirements for
in-process quality control. the
same time, the SMT optimised male headers from Weidmüller
increase the assembly strength due their low weight. not
only has high dimensional stability, but also good resistance to
the heat soldering. Additionally, collisions between the
components and the PCB can completely avoided.
Reflow solder the material the future
High temperature resistant, halogen free insulating material LCP
(Liquid Crystal Polymer) has melting point 335°C
