Can relays be entirely cleaned after mounting on a PCB, and can ultrasonic cleaning be applied?
Entire cleaning can be applied to the plastic-sealed relay. If ultrasonic cleaning is required, you must select a model supporting ultrasonic cleaning.
Refer to the table below to select a cleaning method and cleaning solution.
For more information, see Safty Precautions for All Relays: 6-10 Automatic Mounting of Relays for PCBs.
If a PCB on which multiple relays are mounted is cleaned, a cleaning residue is likely to be generated. Always check for residue, as cleaning residue may cause corrosion and insulation degradation.
