5.0 Mechanical Integration
Mounting the MicroJoystick
There are a variety of mounting methods available to the integrator. The MicroJoystick may be
mounted on the frame of a keyboard, either by mounting it directly on top of the frame or by
mounting it from underneath the frame with the stick protruding through the frame. Its compact
size easily fits within the constraints of most notebook keyboards. In addition, the MicroJoystick
can be mounted on a case or bezel, or directly to a printed-circuit board. Figure 1 on the next
page shows the dimensions of the MicroJoystick assembly.
How to Adhere to Printed Circuit Board
Never solder directly to the connecting traces on the printed circuit board of the MicroJoystick; the
material used for the conductive pattern is not solderable. Instead use standard or custom flex
circuit attached using heat-bonded anisotropic conductive adhesives or pressure-sensitive
anisotropic adhesives. However, in order to ensure that the pressure-sensitive adhesive joint is
robust and reliable, a compressive force must be applied to the adhesive joint. A molded-in rib or
mechanical clamp can be used to supply the compressive force.
