1. What is PCB Corrosion? PCB corrosion is a major cause of electronic product failures. Initially, corrosion increases the resistance of the copper traces on the circuit board, but as the level of corrosion increases, the efficiency of the PCB decreases, and it may even stop functioning. Corrosion is an oxidation process that occurs when … Read more
After the delivery of a previous design project, due to an operational error by the on-site debugging personnel, the exposed wire ends touched the circuit board (which was coated with a conformal coating) when the rear panel of the device was removed, ultimately causing a short circuit. The feedback from the site indicated that the … Read more
What is PCB Conformal Coating? PCB Conformal Coating, also known asPCB Coating or protective coating, is a specially formulated adhesive coating used to protect printed circuit boards (PCBs) and their associated devices from environmental factors. It can form a protective film on the surface of the PCB, which has various protective functions, thereby enhancing the … Read more

This product is synthesized from modified acrylic resin materials through fine processing, featuring high transparency, high gloss, high fullness, good adhesion, excellent insulation, high weather resistance, efficient salt spray resistance, moisture resistance, and mildew resistance, making it a three-protection conformal coating product.
Traditionally, conformal coating technology specifically refers to the moisture-proof, mildew-proof, and salt spray-proof performance of electronic devices. Conformal coating technology mainly involves experimental research and engineering applications related to environmental conditions, environmental design, process protection, and testing technology for electronic devices. Previously, an article titled “Introduction to Conformal Coating Process” was written; this article focuses … Read more
Conformal coating is a specially formulated paint used to protect circuit boards and related equipment from environmental corrosion. Conformal coatings have excellent resistance to extreme temperatures; once cured, they form a transparent protective film that can protect circuits from damage under conditions such as exposure to chemicals (e.g., fuels, coolants), vibrations, humidity, salt spray, moisture, … Read more
Conformal coatings were originally applied only in high-tech fields of printed circuit boards (automotive industry, aerospace, and maritime). As electronic devices are increasingly used in daily life, consumers are also paying more attention to product quality and reliability. The use of conformal coatings allows manufacturers to effectively improve product quality, and thus they are now … Read more
