Hey there! I'm part of a component failure analysis supplier, and today I wanna talk about how improper storage can lead to component failure.
Let's first understand what we mean by improper storage. It could be anything from storing components in a place with the wrong temperature and humidity levels to keeping them in an environment full of dust and contaminants. Components are like delicate little machines, and they need to be treated right if they're gonna work properly.
One of the big problems with improper temperature storage is thermal stress. Components are designed to work within a certain temperature range. If they're stored in a place that's too hot, the materials inside can expand. And when they cool down, they contract. This constant expansion and contraction can cause cracks in the components. For example, a printed circuit board (PCB) might develop micro - cracks in its conductive traces. These cracks can disrupt the flow of electricity, leading to intermittent or complete failure of the component.
Humidity is another major culprit. High humidity can cause corrosion. When moisture in the air comes into contact with metal parts of a component, it can start a chemical reaction. This corrosion can eat away at the metal, weakening the structure of the component. Take a connector pin as an example. If it gets corroded, it might not make a proper electrical connection, which can lead to signal loss or even a short - circuit.
Dust and contaminants are also bad news. They can get into the tiny spaces between components and cause mechanical problems. A fan in a computer component might get clogged with dust. When the fan can't spin properly, it can't cool the component effectively. This can lead to overheating and eventually component failure.
Now, let's talk about how we can figure out if improper storage was the cause of component failure. That's where our component failure analysis services come in. We use a bunch of different techniques to diagnose the problem.
One of the important tests we offer is Ion Cleanliness Testing. This test helps us detect the presence of ions on the surface of a component. If there are a lot of ions, it could be a sign of contamination, which might have happened during storage. For example, if a component was stored in an area with a lot of chemicals in the air, these chemicals could leave behind ions on the component's surface.
Another useful service is Power Module Aging and Test Verification. This helps us understand how a component behaves over time. If a component fails early, and we find that it has aged prematurely, improper storage could be the reason. Maybe it was stored in a place with high temperatures, which accelerated the aging process.
We also use X - Ray NDT Testing. This allows us to see inside a component without taking it apart. We can look for cracks, voids, or other internal problems that might have been caused by thermal stress or mechanical damage during storage.
Let's take a real - world example. A company had a batch of electronic components that started failing after a few months of storage. They came to us for help. We first did the Ion Cleanliness Testing and found high levels of ions on the components. Then, using X - Ray NDT Testing, we discovered some micro - cracks in the PCBs. After further investigation, we found out that the components were stored in a warehouse with high humidity and poor ventilation. The humidity caused the corrosion and the presence of contaminants led to the high ion levels. The micro - cracks were likely due to thermal stress from temperature fluctuations in the warehouse.
Improper storage can have a domino effect on components. It can start with small issues like corrosion or micro - cracks, but these can quickly escalate into major problems. For instance, a small crack in a capacitor can lead to a short - circuit, which can then damage other components in the same system. And once a component fails, it can be costly to replace. Not only do you have to buy a new component, but you also have to factor in the cost of downtime if the component was part of a critical system.
So, what can you do to prevent component failure due to improper storage? First, make sure to store components in a controlled environment. Keep the temperature and humidity within the recommended range. Use proper storage containers to protect components from dust and contaminants. Also, keep a record of the storage conditions. This can be really helpful if a component does fail, as it gives us a starting point for our failure analysis.
