Land Pattern
The recommended surface mount pad pattern ensures
quality solder joint formation and high-yielding assembly,
while using minimum board space. The dimensions apply
to both Solder Mask Defined (SMD) as well as Non-Solder
Mask Defined (NSMD) pads. However, NSMD pads, in
which the solder mask is pulled back from the metal pad,
are preferred. This type of pad definition generally
produces improved solder joint reliability as well as an
increased gap under the component. The increased gap
is desirable for enhanced cleaning of flux residue and
component underfill for applications in which the
component will be encapsulated.
The solder deposit should be centered on the land pattern
as shown.

Solder Printing
The recommended land pattern, when used in
conjunction
with
the
following
solder
deposit
recommendation, provides quality solder joint formation
and high yielding assembly. Solder should be deposited
with a stencil of foil thickness from 100–125
m, and
preferably have apertures that are laser-etched and
electro-polished for optimal paste release. The chip scale
package is compatible with most lead-based and lead-free
solder pastes, though a type 3 or type 4 paste is preferred
for the fine aperture printing.
Component Placement
The CSP can easily be picked and placed on most
placement systems. Care should be taken to select a pick
nozzle that matches the component footprint. Vision
alignment after pick can be done to the package edges or
the package leads, depending on the ability of the individual
placement machine. The component should be placed as
centered as possible to the pad and print patterns to assure
even wetting and an absence of tilt or skew.
