Recommended Solder
Paste/Cream Volume for
Castellation Joints
Based on calculation and experi-ment,
the printed solder paste volume
required per castellation pad is 0.22
cubic mm (based on either no-clean
or aqueous solder cream types with
typically 60% to 65% solid content by
volume). Using the recommended
stencil results in this volume of solder
paste.
Pick and Place
Misalignment Tolerance
and Self-Alignment after
Solder Reflow
If the printed solder paste volume is
adequate, the HSDL-3201 will self
align after solder reflow. Units should
be properly reflowed in IR/Hot Air
convection oven using the recom-
mended reflow profile. The direction
of board travel does not matter.

Direction Definition
Tolerance for X-axis Alignment of
Castellation
Misalignment of castellation to the
land pad should not exceed 0.2 mm
or about one half the width of the
castellation during placement of the
unit. The castellations will self-align to
the pads during solder reflow.
Tolerance for Rotational (q)
Misalignment
Mounted units should not be rotated
more than 3 degrees with reference
to center X-Y as shown in the direction
definition. Units that are rotated more
than 3 degrees will not self align
after solder reflow. Units with less than
a 3 degree misalign-ment will self-
align after solder reflow.

Y-axis Misalignment of
Castellation
In the Y direction, the HSDL-3201 does
not self align after solder reflow. Avago
recommends that the part be placed
in line with the fiducial mark (mid-
length of land pad.) This will enable
sufficient land length (minimum of
one half of the land pad) to form a
good joint. See the drawing below.
