Printed Circuit Board Assembly Services: How To Prevent Corrosion

-

With the advent of a data-driven economy, we all depend on complex circuit boards for everything. Learning how to build and provide printed circuit board assembly services is the central task of any technician in this field. However, the management of the systems is of even more importance. Today's blog focuses on one of the principal problems in a circuit board assembly service - corrosion.

4 Tips to Maintain Corrosion-Free PCB

Cleanliness and Contamination Control

Indeed, one of the most overlooked causes of a dirty and corroded circuit board is the accumulation of dust and pollutants on its surface.

We all know how fragile the tiny parts on a build-to-print system can be; and grime can get right into the Greeks and crewises of these parts allowing for moisture to build up - essentially causing a deep level damage that is impossible to cure.

Environmental Protection Measures

Ideally, the printed circuit board should never be left out in the open where it can directly come in contact with humidity and air molecules. There are several great but affordable ways of storing PCB where it is safe.

These can include:

● Storing PCBs in a dry and cool place, away from direct sunlight

● Covering them with a shade made of corrosion-resistant materials

● Use anti-static bags and desiccant packets, for protection

● Never bring the unit close to extreme temperatures or great temperature fluctuations

Material Selection and Design Considerations

During the NPI electronics manufacturing process, it is possible to keep material selection and design under strict control. In fact, this is a vital necessity if we want to protect the production quality of a PCB.

There are several steps during designing, prototyping, and actual circuit boards where strict ethical standards and regulations can be imposed so that we stay away from low-quality materials that can easily get corroded.

Conformal Coating Application

This is all about applying a clear, protective layer on top of the board components. Its job is to protect the board from moisture and dust.

The application process of this coating substance is easy and quick. The layer is applied using a variety of methods, like spraying or dipping, and then it's cured in an oven to make it all hard and durable.

The better quality of the conformal coating, the longer a PCB board is likely to last in environments that are corrosive to its body.

Last Thoughts

Proper management of the corrosion is also helpful when administering the proper solution. We should understand that PCB getting corroded can have several reasons - being exposed to moisture, humidity, or water; being set up against leaking, harmful chemicals, etc. These things can happen due to poor storage, humid environments, or physical damage. A bad PCB is infectious to all other components of the system, so treating it is crucial.

Have you ever wondered why some electronic devices fail unexpectedly while others function normally for years? Often, it is the heart of such electronic devices-a printed circuit board-that fails. But what happens during its manufacturing process and how could those problems be solved? Let's delve into the world of PCB assembly and uncover common pitfalls as well as their solutions. Component Misalignment Poor component alignment is one of the most common issues in PCB manufacturing assembly . Essentially, it is a situation in which parts are well placed on the board but will result in either better connections or short circuits. Imagine a highly unstable Lego structure by putting off-center pieces onto it-it just collapses. The way to counter this is using advanced high-precision pick-and-place machines. These machines can position the components as small as down to a fraction of a millimeter accurately. Regular calibration and maintenance of these machines are essential. Optical ...
