$GTCH The device is assembled based on the most up-to-date SMT (Surface Mount Technology). SMT is a method in which the electronic components (microchips, resistors, capacitors) are mounted directly onto the surface of a printed circuit board (PCB). SMT is an efficient method to create small electronic devices and to increase manufacturing automation which reduces cost and improves quality. It also allows for more electronic components to fit on a given area. qTerm prototype includes a PCB with IR and optical sensors, LEDs for visual feedback, battery and its enclosure.
