1
Use the information provided in Chapter 2 to design pads on your
board and holes for mounting the retention module.
The soft touch probes are attached to the PC board using a retention
module which ensures pin-to-pad alignment and holds the probe in
place.
2
Use flux as necessary to clean the board and pins before soldering the
retention module to the board.
3
If your board has Organic Solder Preservative (OSP) finish, apply solder
paste to the footprint pads prior to re-flow or hand soldering.
Typically, dipped and coated finishes do not require extra solder paste.
4
Attach the retention module to the board from either the top or bottom
of the board:
Top-side attach
Can be used with most board thicknesses.
a Insert the retention module into the board noting the keying pin.
b Solder alignment pins from the top ensuring that solder is added
until a fillet is visible on the pin.

Bottom-side attach
Can be used for board thickness of 2.54 mm (0.100 in.) or less.
a Insert the retention module into the board noting the keying pin.
b Solder the alignment pins to the back side of the board.
5
Insert the probe into the retention module.
