SMT Nozzle how to affect the placement speed 

1） Internal reason
One hand smt nozzle is the lack of vacuum pressure, smt nozzle the automatic conversion of the head of the mechanical valve, from the blowing into it really adsorption, resulting in a certain negative pressure, as absor the part, the sensor is within a certain range, the machine is normal and vice versa. Generally, the negative pressure at the nozzle position should be at least 400mmHg. When the negative pressure of the large device should be above 70mmHg, the filter in the vacuum pump should be cleaned regularly to ensure sufficient negative pressure. At the same time should regularly check the negative pressure detection sensor working status. On the other hand is the placement of the head of the filter and the nozzle on the filter due to the surrounding environment or gas is not pure pollution blocked and black. So the filter should be replaced regularly, the general nozzle on the filter should be replaced at least half a month, the top of the filter should be replaced at least six months to ensure that the air flow patency.
2）External causes
On the other hand is the air source circuit pressure relief, such as rubber pipe aging, rupture, seal aging, wear and nozzle after a long time using wear, due to adhesive or external environment dust, the components in the cut off after a large number of waste generated, resulting in patch machine nozzle block, so the daily inspection of the cleanliness for the nozzle, at any time to monitor the nozzle of the pick-up situation, Should be promptly cleaned or replaced to ensure a good condition, while the installation of the nozzle, you must ensure that the correct, solid installation, otherwise it will cause damage to the nozzle or equipment.
