FR 4 Blends are Super Special Materials We use to build all great electronic devices Ever wondered what’s inside your phone or computer, or a video game machine? It's a material called FR 4! This cool material is composed of little glass threads and a sticky thing called resin. Think of it as tiny glass strings woven together to create something that is strong and useful.
FR 4 is extremely, very powerful. When companies manufacture this material into circuit boards, they are able to be sure that the circuit boards will not break easily. The point is that if you drop a device it's less likely to break and the circuit board inside is less likely to be damaged. It isn’t costly, either, which is great news for companies that produce all our favourite electronics.
FR 4 is like a superhero that keeps the electricity in place with some amount of dielectric constant. Just as a fence keeps animals contained in a yard, FR 4 keeps electrons from escaping. The device works much better when electricity doesn’t escape to where it shouldn’t. That your phone, computer or game machine will be Saturn smooth and do what you want.

It is an incredible material with some very interesting features. Heating hot without being damaged First, it has the ability to withstand very high temperatures. Think of FR 4 like something that you touch that's really hot that doesn't shatter or melt. It’s also quite difficult to catch on fire. That makes it especially safe to use in all of our electronic appliances.

FR 4 is used to facilitate the speedy movement of electricity through circuit boards. When electricity travels quickly, the performance and speed of electronic devices can be enhanced. Think of it as your device's turbocharged boost! The quicker the electricity moves, the faster your device can do what you wish it would do.

Think of cooking FR 4 as a special recipe. Laborers dip slender glass fibers into an adhesive mixture. Then, they press and heat the material to form it into a solid and strong structure. It’s sort of like baking a cake, but instead of creating something delicious, they’re creating something that helps our electronics work just right!
