7.2 1-Sided Key Layout
This key design can be made on a 1-sided SMT PCB. A single 0-ohm jumper
allows the wiring to be done on a single side with full pass-through of X and Y
traces to allow matrix connections to be made across a large number of keys.
Key size, shape, and number of interleavings can be varied substantially from
this drawing. The below drawing shows 6 interleave white spaces; only a
double interleave is required in the case of smaller keys.
The PCB is bonded to a panel on its underside, and the fields fire through the
PCB, adhesive, and panel in that sequence. This results in a very low cost
design.
7.3 PCB Layout
Shown is an example PCB layout using inexpensive 1-sided CEM-1 or FR-1 PCB laminate. The key layouts follow the design
rules shown above. (PCB design shown uses a QT60326 chip but still represents a good example).
