Mechanical
Construction
The CarrollTouch IR XRES frame is a solid state circuit card
assembly. The circuits are populated onto .062" thick FR4
printed wiring board material with a UL flammability rating
of 94V-0. The IR transparent insert attached to the circuit
card assembly is polycarbonate material with a UL
flammability rating of 94V-0 at thicknesses of .090 inches
and above, and 94V-2 at thicknesses from .034-.089 inches.
Cable and Connector
The cable exits from the left center of the frame assembly
and is a 16 position, 0.5 mm flat flex cable (FFC). The cable
terminates into a ZIF connector on both sides of the
controller and frame interface.
The FFC cable can be folded and creased. Test data for this
cable reveals that the cable maintains electrical
characteristics over 20 million cycles of a simulated forming
bend around cylinders of radius 0.5", 0.75", and 1.0". The
FFC is guaranteed to maintain electrical and plating
characteristics for a minimum of 25 insertion and withdrawal
cycles with the ZIF connector.
Positional Accuracy
The positional accuracy of the IR XRES frame to a touch
stylus is a function of the physical spacing of the discrete IR
opto-electronics, diameter of the touch stylus, and location of
the stylus in the touch active area. The table below provides
the positional accuracy specifications with corresponding
XRES product and dimensional determinants.
