Importance of Clean Printed Circuit Boards

When it comes to PCB board manufacturing, most people focus largely on the actual design of it since this is what has the biggest impact on the board’s capabilities. However, there are several other very important factors to consider when it comes to printed circuit board fabrication.

One of these crucial qualities is making sure that the PCBs are as clean as possible. When getting these products from any good printed circuit board companies, this should be something that is always done. But it is still important for you to know why having clean printed circuit boards is so important and what can happen when they are allowed to get dirty.

Issues Caused By Excessive Dust Buildup

During the PCB board manufacturing process, one of the things that is going to be used every time is flux. This is because it is necessary to be able to properly wet the metal solder and form metallurgical bonds. But as a result of this process, there is sometimes some residual flux that is left behind. As soon as this happens, it is going to start attracting dust and cause the PCB to become coated in a thin layer of dust much faster than it otherwise would be.

This can often lead to the MCU becoming negatively affected. These microcontroller units are generally supposed to be able to operate at a voltage of 0 to 5v. But once some dust or moisture is introduced into the PCB, it instantly impacts the voltage level that is able to be transferred and drastically increases the chances of a short circuit forming.

The other way that dust negatively impacts these PCBs is by inhibiting the airflow levels, which causes the heat produced by the various components to be dispersed at a much slower rate. Therefore, an excellent printed circuit board fabrication can be easily ruined by a simple buildup of dust.

What Excessive Humidity Causes

When a PCB is regularly used and cleaned, the level of humidity is likely not going to build up to dangerous levels. However, this changes once the PCBs are left uncleaned for long periods of time, at which point they humidity levels can reach levels where they are able to cause oxidation to occur.

In order to make sure that the PCB board manufacturing doesn’t go to waste, you need to make sure that you are protecting your PCBs by regularly cleaning them. Get your clean and ready to use PCBs from us at Star Engineering today.
