The IR start sensor is for touchless board temperature measurement. Reportedly requires no in-process handling. A laser pointer helps find the best measuring spot. Is characterized by a profile reliability of +/-5°C and is said to permit increased peak temperature accuracy. The PCB is only exposed to as much heat as is necessary. Existing placer control boxes can be retrofitted with the infrared start sensor.
