4.2 Mounting PLSx3 onto the Application Platform
This section describes how to mount PLSx3 onto the PCBs, including land pattern and stencil
design, board-level characterization, soldering conditions, durability and mechanical handling.
Note: To avoid short circuits between signal tracks on an external application's PCB and vari-
ous markings at the bottom side of the module, it is recommended not to route the signal tracks
on the top layer of an external PCB directly under the module, or at least to ensure that signal
track routes are sufficiently covered with solder resist.
4.2.1 SMT PCB Assembly
4.2.1.1 Land Pattern and Stencil
The land pattern and stencil design as shown below is based on Thales characterizations for
lead-free solder paste on a four-layer test PCB and a 110 respectively 150 micron thick stencil.
The land pattern given in Figure 37 reflects the module‘s pad layout, including signal pads and
ground pads (for pad assignment see Section 2.1.1).

The stencil designs illustrated in Figure 38 and Figure 39 are recommended by Thales as a re-
sult of extensive tests with Thales Daisy Chain modules.
