Using a Food Dehydrator to Dry Cleaned PCBs: Tips and Considerations

After cleaning your PCBs with an ultrasonic cleaner, it’s important to ensure they are thoroughly dried to prevent water damage. Some suggest using a hot air blower for this purpose, but have you considered using a food dehydrator instead?

While a food dehydrator can effectively dry PCBs, there are concerns about potential static charge buildup due to the plastic construction of the dehydrator. This static charge could be harmful to the sensitive components on the PCB.

If you decide to use a food dehydrator, it’s advisable to take precautions to dissipate any static charge. One option is to create a wire mesh with a grounding wire to neutralize the static electricity. However, the effectiveness of this method may vary.

Before proceeding, it’s essential to gather more insights and recommendations from experts in the field to ensure the safety and integrity of your PCBs. Share your thoughts and experiences with the community to make an informed decision!
