In the production process of modern electronic products, PCB (printed circuit board) is one of the core components, especially in products that require long-term stable operation, the protection of wiring terminals and solder joints is particularly important. A certain electronic manufacturing company is facing severe challenges when producing PCBs for industrial equipment. Wiring terminals and solder joints are often exposed to harsh environments such as high temperatures, moisture, dust, and chemical corrosion. These environmental factors not only easily lead to circuit short circuits, corrosion, and solder joint damage, but also may cause product failures, thereby affecting the stability of the entire system and customer satisfaction.
Especially in scenarios that require waterproofing and moisture resistance, traditional solder joint protection methods often fail to provide sufficient sealing and bonding strength, ultimately affecting the long-term service life of the product. Therefore, the company urgently needs a material solution that has excellent waterproof, moisture-proof, and corrosion-resistant properties, while effectively enhancing the strength of solder joints and protecting wiring terminals.
