E-tec Socket Mounting Recommendations
PRELIMINARY
2
Stencil
Table 1 shows the recommended stencil dimensions. A laser-cut, electro-polished and Ni-plated
stainless steel stencil is recommended to give the most consistent paste release. The apertures
can be made round except for smaller pitches, where square apertures are recommended.
Remember to keep the stencil small enough to fit within the keep-out area of the socket, but yet
have provisions to remove it from the PCB once the paste has been applied.

Solder Paste
E-tec recommends using solder paste without ( or <0.5%) silver (Ag) to reduce the solder’s
wetting ability and prevent the paste from running up the pins, thus maximizing the volume of
solder left on the pads. Brands such as Qualitek (www.qualitek.com) or Alpha Metals
(www.alphametals.com) produce such solder paste on customer request. For Sn/Pb solder paste
we recommend Ecorel 803S offered by Avantec (www.avantec.dehon.com).
Reflow Profile
Both standard Sn-Pb eutectic and Pb-free reflow profiles are shown below.
