<p>Without the invention of the printed circuit board (<a href="https://www.atechpcb.com/" target="_blank">PCB</a>), almost all the technologies we rely on would be impossible. PCB makes it possible for humans to reduce the size of electronic devices. Moreover, humans can now manufacture powerful equipment cheaply.</p><p><br></p><p> </p><p><br></p><p>Nowadays,<a href="https://www.atechpcb.com/" rel="noopener noreferrer" target="_blank"><strong> PCB</strong></a> is almost everywhere. PCB contains some exposed or bare components, which may oxidize and corrode, thereby terminating the function of the circuit board. Therefore, PCB coating must be performed. By coating the PCB with a conformal coating, you can protect you. You can also protect its components from corrosion. This article points out 15 things to note about <a href="https://www.atechpcb.com/" rel="noopener noreferrer" target="_blank"><a href="https://www.atechpcb.com/" target="_blank">PCB conformal coating</a>s</a>.</p><p><br></p><p><strong>1. What is PCB conformal coating?</strong></p><p>When talking about the PCB field, you may have heard the term PCB conformal coating? But what exactly is a <a href="https://www.atechpcb.com/" rel="noopener noreferrer" target="_blank">PCB</a> conformal coating? As the name suggests, PCB conformal coating is to apply a thin film of a certain protective material to the circuit board. The coating protects the entire circuit board and its parts. These parts include component leads, exposed traces, solder joints and exposed metal.</p><p>Conformal coating protects metal parts from fungus, moisture, spray and other environmental pollutants.</p><p><br></p><p><br></p><p><strong>2. Use of PCB conformal coating</strong></p><p>The main purpose of PCB conformal coating is to protect electronic components from environmental factors and corrosion.</p><p><br></p><p><br></p><p>•Used as an insulating material for PCB, while minimizing ecological pressure during PCB assembly. It helps eliminate the need for complex enclosures;</p><p>• Protect the PCB from heat, humidity, fungi and airborne pollutants (such as dust).</p><p><br></p><p><br></p><p><strong>3. Advantages of PCB conformal coating</strong></p><p>The following PCB conformal coatings have many advantages:</p><p><br></p><p>•Insulation and heat resistance</p><p>• Lightweight</p><p>•Protect PCB components</p><p>• Reduce environmental hazards to PCB boards and prevent pollutants from entering</p><p>• Less PCB assembly footprint</p><p>•Enhance product reliability</p><p>•Extend the service life of printed circuit boards</p><p>• Very easy to apply</p><p><br></p><p>A-tech is a professional <a href="https://www.atechpcb.com/" rel="noopener noreferrer" target="_blank"><strong>pcb manufacturer</strong></a> in China, Contact us!</p>
