Do you take computer or electronic things. If you do, then I have a large green brick that will be wiggling all around with tiny circuits everywhere. This green board is a printed circuit board, PCB for short. The PCB is manurfactured using a special material called epoxy glass FR4. These are produced by blending woven glass fibers with a viscid liquid known as epoxy resin. The PCB has gained its strength and durability through the combination of these materials. It is very crucial for us as PCB contains all the small parts which aid other devices to work properly.
Epoxy glass FR4 circuit boards have a reputation for being extremely robust and durable. These glass fibers, which typically come in woven form (think basket weaving), bring a ton of strength to the material; and just like with anything without epoxy resin as an adhesive you would find very quickly how shoddily thrown together these parts are. Epoxy glass FR4 circuit boards are incredibly resilient which makes them perfect for electronic devices that could be exposed to harsh conditions including hot temperatures or vibrations. Moreover, these boards are also moisture and chemical resistant which can be used for different purposes in a range of industries including automotive, aerospace as well as military applications.
Epoxy Glass FR4 FeaturesAdvantagesThere are plenty of advantages that come with using Epoxy glassFR- which is why it's one of the best materials for making circuit boards. Well the biggest advantage is that it is incredibly strong and hardwearing, able to withstand a great deal of punishment. Another key benefit is that it does not conduct. This, in turn means it does not inhibit the electrical circuits that it holds together and must be held tightly to maintain a signal; vital for operation. It is a great insulator, and its structure does not compress or deform when pressure is put on it. It is also fireproof and high heat resistant --> which are essential to avoiding a disaster.
Importantly, all these comes with a few disadvantages of using the epoxy glass FR4 too. On the downside, it can be a little more costly than some other materials. That can make it less user-friendly for certain projects. Epoxy glass FR4 also has the disadvantage that it may be more challenging to work with. This typically is because it needs to be dealt with in specialized manners that require specific tools and know-how. Moreover, cloth fibers within the material may be a breeding ground for lung irritation in case it is breathed — so use caution whilst operating with this particular compound also and utilize suitable securityen auflistung.
The last thing you need to consider is the weave pattern of the material. The material has different properties based on weave pattern, and you would choose the appropriate one for whatever use case is required. The particular weave — say, a basic plain variety that confers high strength and flexibility or the distinctive twill type (think denim) incorporating raised diagonal patterns to augment stiffness and fight torsional forces.
Epoxy glass FR4 circuit boards are VERY durable and should last a long time, but only if they receive proper care and maintenance. Tip number one: BE CAREFUL!!!! Be sure to handle the boards with care, so as not to drop them or bang them together in a way that would damage them. wow! Keep the circuit boards in a cool, dry and clean place away from any damp that could potentially damage to their delicate circuity.
Besides that, you should not clean these boards using corrosive chemicals or strong solvents. These can eat away at the epoxy resin causing damage that will affect your board ride quality. However, washing the epoxy glass FR4 — instead of wet and dry vacuuming is a better way even if you will prefer to use mild soap in water. Also, ensure that the removed material is in suitable temperature/humidity conditions as this will have a substantial impact on the properties and performance of our phenolic sheet over time.
