Conformal coatings are used to protect printed circuit boards within electronics. Without this protection, electronics would fail after contact with a chemical, water, or other environmental hazards. Many industries use conformal coatings, but the military is an example of an industry that needs their devices protected from extreme situations.
A PCB, or printed circuit board, connects and powers electronics large and small. These components are delicate and need to be protected accordingly. Here’s your guide to conformal coating for PCB’s.
Many people have never heard of parylene before, but when you work in an industry that deals with minuscule technological items that need protection you are surrounded by it. Here are three things to know about parylene.
The protective properties of parylene also this conformal coating to be used in industries from common individual products to aerospace, and military forces.
Unless you work in a particular industry, it’s possible you’ve never heard of parylene. For those who work in fields that create devices with printed circuit boards then you know what we’re about to talk about. The history of parylene shows its widespread and dual uses.
In the world of conformal coating, there are many to choose from. Each boasts their unique protection traits and what set them apart of the others. So it's important to break down what your product's specific need is. In other words, what does your product need to be protected from the most? Water, extreme temperatures, or maybe even gases.
When applying a conformal coating, there are components whose functionality would be disrupted by the coating. To prevent this, a masking process is used. This masking is applied to connectors, header pins, plugs, and sockets.
A printed circuit board (or PCB) supports and connects electronic components within everyday devices. There are water resistant phones and waterproof watches, but how are the printed circuit boards protected? Coating the board adequately is extremely important otherwise any missed point is a potential shorting point. Here’s how you can waterproof a printed circuit board with parylene.
Parylene is used medical, aerospace, military and almost every other industry we can think of. It's applications are as varied as its benefits and has an impressive list of advantages over other conformal coatings. Taking an even closer look shows that the different types of parylene have their own unique benefits. Each of the three types is best for a certain kind of job.
When considering to conformal coating to use to protect your product, there are a lot to choose from. And more than just the conformal coating properties are taken into account. Cost, availability, and even logistic play a role in deciding what coating to use.
