Static electricity is a common problem in manual workspaces. Even grounding and other countermeasures are usually insufficient to eliminate the static problems that occur. Using an ionizer can be the solution that makes the difference.
Electrostatic discharge can be prevented during PCB inspection to reduce the risk of defects during product assembly or after shipment even for products that have already passed inspection.
Static elimination can still be performed using a tube even in equipment with no space for installation of an ionizer.
During transport, PCBs become statically charged due to contact and separation from conveyor belts. Strong charges can lead to electrostatic destruction and adhesion of foreign particles, which in turn can lead to manufacturing defects. An ionizer can reduce these defects by eliminating the electrostatic charge.
A foreign object between the probe and the PCB during conductivity testing is considered a conductivity defect and means the test has to be repeated, greatly reducing the yield. Sensitive probes can even be damaged by the static electricity. An ionizer can eliminate these problems.
Parts become statically charged due to friction and debonding during assembly. Countermeasures are required for this charge, as it can introduce foreign particles into the parts, resulting in noise in the images. An ionizer can prevent adhesion of foreign particles.
