Precautions
■ Attaching to the PCB
Remove the Dome Key from the sheet using tweezers or a vacuum
pick-up tool, and attach it above the contact on the PCB surface,
which has been wiped clean in advance. Press down on the top sur-
face using an elastic material, such as urethane rubber, and a force
of 2.94 to 4.9 N. Place a positioning mark (circle) on the PCB for
easy positioning.
Make sure that the position of the Dome Key is aligned correctly
before use. Significant misalignment may result in short-circuits or
reduced sensitivity.
Note: The recommended vacuum pick-up tool is the Hozan P-835
Vacuum Pick with an M suction pad (7-mm dia.).
Do not reuse a B3D Dome Key that has been detached from the
PCB. Attach a new Dome Key to the PCB.
Do not touch the contact dome with bare hands, or with unclean
gloves. Doing so may damage the contact dome, which is the part
that comes in contact with the PCB.

■ Reflow Soldering
The Dome Key cannot withstand heat from reflow soldering. Always
perform reflow soldering before attaching the Dome Key to the PCB.
■ Washing
Do not wash the Dome Key. The Dome Key is not water-resistant and
must not be exposed to water or other liquids.
■ Common Precautions
Be sure to read the precautions common to all Tactile Switches,
contained in the Technical User’s Guide, “Tactile Switches, Technical
Information” for correct use.
