Hello experts,
What are the requirements in regards ionizer air guns? how do you include this in your program?
Thanks for the guidance,
Santiago,
They are the same requirements for other ionizers listed in ANSI/ESD S20.20 Table 3 (Discharge time is user defined and offset voltage is between -35 volts and +35 volts for both product qualification and compliance verification). The measurement method is slightly different from other ionizers. ANSI/ESD STM3.1 section 6.4 gives the process for product qualification. ESD TR53 section 7.3.11 (using figure 29) gives the process for compliance verification.
Usually, ionizer air guns are used where you don’t need constant ionization and where the flow rate will not cause small components to be blown around. I have seen them used at a solder station to blow off any additional flux residue from PCBAs
Hello
Greetings of the day from India .
Especially in the automotive sectors and high precision Instrumentation and also in the mobile phone industry Ionizing Air gun play a vital role to neutralize the charges in the enclosures before the assembled PCBs are fitted and connected inside them . Unlike the normal table top or overhead type ionizer the Air gun with its nozzle will be focusing on a particular object for more effective neutralization. Even in the PCB mfg industry during Plated through hole inspection process it is ideal.
As Andy Sir has described, the requirements to be met for Ionizers per S 20 . 20 will only apply to the Ionizing air gun too and the CV procedure with figure is described and shown in TR53^(R)-01-22
Thank you
