Most electronics engineers know that water and electricity don’t mix. As a result, circuit boards need to be protected from moisture. But what’s the best way to do this? Should circuit boards be waterproofed or not? To answer this question, we’ll need to consider the pros and cons of each option.
On one hand, waterproofing circuit boards has its advantages. It prevents water from reaching the delicate electronic components, which could otherwise cause damage or even destroy the board. Additionally, it increases the board’s durability and extends its lifespan. In some cases, it can even help protect against dust, dirt, and other environmental contaminants.
Despite these benefits, there are downsides to waterproofing circuit boards. For one, it adds an extra layer of cost to the manufacturing process, as materials and man-hours are required to make the board waterproof. Furthermore, waterproofing makes it more difficult to repair the board in the event that something goes wrong. This can lead to substantial delays in getting the board back up and running.
Ultimately, the decision to waterproof or not should come down to the application and expected environment. If the board is going to be exposed to moisture, then waterproofing is likely a good idea. However, if the board will remain dry, then it may be best to skip the waterproofing step altogether, as it’s not necessary and can add additional cost.
In short, whether or not to waterproof a circuit board largely depends on the situation. In some cases, it’s beneficial, while in others it’s unnecessary. Ultimately, it’s up to the engineer to weigh the pros and cons in order to make the best decision for the job.
