circuit board, solder paste must be applied to the pads. Solder
stencils are used to screen the optimum amount. These
stencils are typically 0.008 inches thick and may be made of
brass or stainless steel. For packages such as the SC–59,
SC–70/SOT–323, SOD–123, SOT–23, SOT–143, SOT–223,
SO–8, SO–14, SO–16, and SMB/SMC diode packages, the
stencil opening should be the same as the pad size or a 1:1
registration. This is not the case with the DPAK and D 2 PAK
packages. If one uses a 1:1 opening to screen solder onto the
drain pad, misalignment and/or “tombstoning” may occur due
to an excess of solder. For these two packages, the opening
in the stencil for the paste should be approximately 50% of the
tab area. The opening for the leads is still a 1:1 registration.
Figure 18 shows a typical stencil for the DPAK and D 2 PAK
packages. The pattern of the opening in the stencil for the
drain pad is not critical as long as it allows approximately 50%
of the pad to be covered with paste.
temperature of the device. When the entire device is heated
to a high temperature, failure to complete soldering within a
short time could result in device failure. Therefore, the
following items should always be observed in order to
minimize the thermal stress to which the devices are
subjected.

* Soldering a device without preheating can cause excessive
thermal shock and stress which can result in damage to the
device.
* Due to shadowing and the inability to set the wave height to
incorporate other surface mount components, the D 2 PAK is
not recommended for wave soldering.
