SL-SMT 3.5
… reduces costs in the production process
SL-SMT 3.5 is the high temperature resistant
pin header for the 3.5 mm pitch range specially
developed to be compatible with Reflow
production processes. Existing pcb connector
headers cannot withstand the high
temperatures experienced in Reflow soldering -
up to 260 °C. The SL-SMT has been designed
using LCP (Liquid Crystal Polymer) which is
stable at these high temperatures.
In addition, convential assembly of pcb
modules requires both Wave soldering for
standard THT (Through-Hole-Technology)
components like pcb connector headers;
and then Reflow soldering for the SMT
(Surface-Mount-Technology) components.
With the SL-SMT, which uses THR technology,
the Wave solder operation is not needed.
The shorter THR solder pins offer the flexibility
of SMT components but achieve a mechanical
strength of 10x that of “Gull Wing” SMT
components. This additional strength is of great
importance for pcb connectors where
connection operations put strain onto standard
SMT solder joints.
The SL-SMT is not only suitable for the latest
soldering techniques, it has also been designed
to be compatible with standard automatic
“Pick-and-Place” machines. “Tape-on-Reel”
and “Tray” packaging enable fully automatic
component placement of the 90° (horizontal)
and 180° (vertical) pin headers. These products
are available in the standard open-ended,
closed-ended and flanged versions, and mate
with any of the female socket connectors in
our BL 3.5 range.

SL-SMT 3.5 pin headers
At the pcb level, the SL-SMT 3.5 pin header ensures a cost saving in the production
process and, for field wiring, offers a free choice of connection technology thanks to an
extensive range in 3.5 mm pitch.
Packaging types of the SL SMT 3.5
The packaging of the SL SMT 3.5 was conceived for the typical component placement
process used for SMT components:
Automatic component placement:
lꢀTape-on-Reel (ToR)
lꢀTray
Manual component placement:
lꢀStandard box (Std)
The high temperature resistant SL SMT 3.5 pin header can also be used in the wave
soldering process, the advantage being that the plastic is resistant to high temperatures.
For this application however, standard pin lengths are needed. These are available on
request.

For the mounting of PCBs it should be noted, that the rated
data given in the data sheet relate only to the connection
elements. The necessary creepage and clearance paths must
be observed in connection with the respective applicant in
accordance to VDE 0110. The current-carrying capacity is to be
determined according to DIN IEC 326 part 3.
Weidmüller connectors are tested according to the DIN 0627
standard, and are valid for its field of applications. Provided that
the connectors are used for the intended purpose, all
requirements with respect to the occuring of electrical,
mechanical, thermic and corrosive stress will be satisfied.

Tray dimensions and position of SL-SMT 3.5 pin headers
Machine oriented packaging
“Tray”
The optimum positioning points for the vacuum pipette depend on the length of the
connectors (open, closed or flange). In the tray drawing, we have marked these points
with Start X and Step X for the X axis with reference to the example of an
SL-SMT 3.5/24/90 without a flange. The following table indicates the dimensions for the
X and Y axes for the different pole numbers and versions.
To facilitate adjustment on the machine, the label shows the necessary dimension in
short form.

Design recommendation
We recommend design and calculation of the holes and soldering pastes as follows to ensure an optimum soldering result in the
component placement and reflow processes:
•
•
Large fitting hole of the printed circuit board (final diameter) for automatic placement:
ø 1.4+0.1 mm
This fitting hole is recommended to be able to compensate for printed circuit board, component and machine tolerances.
Small soldering eyelets:
ø 2.3 mm
Small soldering eyelets to ensure that as much soldering paste as possible flows into the through-plating (fitting) hole.
Soldering paste calculation
The quantity of soldering paste depends on:
•
•
•
•
•
pcb thickness
diameter (ø) of the pcb’s fitting hole
soldering pin volume in the pcb
soldering paste evaporation
desired soldered joint shape
form factor F 0.6-0.7
form factor F 0.7-0.8
Calculation example:
V
=
1.34 mm3
soldering pin
V
= ((ø fitting hole)2 * π * pcb thickness) / 4
=
=
((1.4 mm)2 * π * 1.6 mm) / 4
2.46 mm3

soldering paste volume

Factor 2 applies only to soldering pastes with a 50% evaporation volume. Adapt this value to other soldering pastes.
Stencil calculation
The stencil surface calculation depends on:
•
•
•
stencil thickness
soldering paste volume
soldered joint shape
Calculation example:
A
=
=
V
soldering paste volume / stencil thickness
stencil hole surface
=
2.24 mm3 / 0.18 mm = 12.44 mm2

A
=
=
(12.44 mm * 4 / π)0.5 * 0.7
2.79 mm
stencil hole-ø
stencil hole surface * 4/π
* 0.7
(
)
2)
The soldered joint form factor for the soldered joint shape recommended by us is 0.7
Important: the maximum diameter of the stencil hole should not exceed 2.8 mm (risk for solder beads forming).
For the soldered joint shape and diameter that we recommend, with a stencil thickness of 0.18 mm and a printed circuit board
thickness of 1.6 mm, this results in a stencil hole of 2.8 mm (see calculation example).
