Pin in Paste Technology

Samtec's SSQ design incorporates standoffs between each tail position (.080” apart) as shown below.



The SSQ is a square tail pin which fills the inside of the hole more than a solder tail would. 

SSQ connector bodies are made from Liquid Crystal Polymer (LCP),  they are lead-free compatible. Compliant with the reflow profile parameters detailed in IPC/JEDEC J-STD-020D which requires that components be capable of withstanding a peak temperature of 260°C as well as 30 seconds above 255°C.  The parts can also withstand three reflow passes.

Stencil aperture design should be similar to that shown below, elongating the relatively narrow apertures outward from the plated through hole.  Additionally, it is highly recommended to include a ‘spoke’ emanating from the annular ring, designed to facilitate the migration of the solder paste to the plated through hole during reflow.
