What to do if the circuit board is in water
With the popularity of electronic devices, water inflow of circuit boards has become a headache for many users. Whether it is a mobile phone, laptop or other electronic device, once water is infeeded, improper handling may lead to permanent damage. This article will combine popular topics and hot contents across the network for the past 10 days to provide you with a detailed solution.
1. Emergency treatment steps after the circuit board is inlet
The following are the key treatment steps after the circuit board is inlet, and be sure to operate in sequence:
| step | Operation Instructions | Things to note |
|---|---|---|
| 1. Power off immediately | Unplug or remove the battery | Avoid short circuit or further damage |
| 2. Remove the housing | Remove the equipment case as much as possible | Avoid sharp tools to prevent scratches on the circuit board |
| 3. Breathe water | Use absorbent paper or cotton cloth to absorb moisture on the surface | Do not wipe hard to prevent the components from falling off |
| 4. Drying treatment | Use a hair dryer to cool air or let it dry | Avoid high temperature baking and prevent component deformation |
| 5. Check for corrosion | Observe for corrosion or oxidation marks | If there is corrosion, use alcohol to clean it |
| 6. Test boot | Make sure it's completely dry before trying to turn on | If the computer still cannot be turned on, it is recommended to send it to repair |

3. Common misunderstandings and professional suggestions
Regarding the water inlet of circuit boards, many users have the following misunderstandings:
1.Misconception 1: Use rice to dry- Although rice has a certain hygroscopic effect, its effect is limited and may introduce dust.
2.Misconception 2: Start the test immediately- Power on when moisture is not completely evaporated may cause a short circuit and should wait at least 24 hours.
3.Misconception 3: Use hot air to blow directly- High temperatures may damage electronic components and cold air mode should always be used.
Professional advice:
1. For valuable equipment, it is recommended to send it to professional repair institutions directly.
2. You can use alcohol with a purity of more than 99% to clean corrosive areas, but be careful to operate.
3. Consider purchasing waterproof bags or waterproof sprays as a precaution.
4. Practical skills to prevent water inlet on circuit boards
1. Stay away from water when using electronic devices, especially in bathrooms and kitchens.
2. Buy waterproof protective covers for the equipment, especially those that are often used outdoors.
3. Regularly check the sealing of the equipment, especially the waterproof rubber rings of old equipment.
4. Consider buying electronic devices with waterproofing, which are more economical in the long run, although they are more expensive.
5. Summary
Water inlet on circuit boards is a common problem for electronic equipment, and timely and correct handling can save the equipment to the greatest extent. Through the detailed steps and data analysis in this article, I hope it can help you make the correct judgment when encountering similar situations. Remember, prevention is better than treatment, and pay more attention to daily use to avoid unnecessary losses.
