In order to kiss off the components with an air blow, there are two times to consider: 1. reaction time of the solenoid ( to shut off the vacuum and turn on the air ), 5-10 ms 2. time required to fill up an air hose, which leads to the nozzle. Assuming air travels in sound speed, than air travels through a 1,000,000 m long hose within an hour or 16,666 m/sec. At least one air particle should reach the end of an 0.16 m long hose in 0.00001 sec. Travel time of the z-axis is approx. 30 ms in one direction. Measuring vacuum or air pressure is done within nano seconds.
Modern chip shooters locate a separate micro processor into the placement head in order to separate some tasks from the main processor and gain some milli seconds.
