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 Traypackaging 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.
