PCB dam sealing and potting – guardians of electronic components

In the trend of miniaturization and high integration of modern electronic products, the protection of electronic components has become particularly important. The dam enclosure and sealing process, as important means in the field of electronic protection, provides comprehensive protection for electronic products, effectively improving their reliability and service life. Dam enclosure technology: building a solid defense lineThe enclosure process, as the name suggests, is to form a “dam” around electronic components or circuit boards to restrict the flow range of subsequent sealant. This’ dam ‘is usually formed by colloids with high viscosity, which not only ensures that the sealant evenly covers the target area, but also avoids colloid overflow and contamination of non target areas.The role of dam enclosure technology:Precise control of sealing range: The dam sealant can precisely define the sealing area, avoiding the sealant from flowing into areas that should not be covered, such as connectors, heat sinks, etc., ensuring the functional integrity of the product.Save material costs: By limiting the amount of sealant used, reduce colloid waste and thus lower production costs.Improving product aesthetics: The dam can make the edges of the sealant neat and beautiful, enhancing the overall appearance quality of the product.Enhance local protection: For certain areas that require local key protection, a dam can form a thicker protective layer, providing stronger mechanical support and environmental protection.Elaplus SIPC 2150 dam sealant: Building a solid foundation for protectionIn order to meet the demand for high-performance protection in electronic products, Elaplus has launched SIPC 2150 single component dealcoholized/environmentally friendly sealant silicone as an ideal choice for dam enclosure processes.As a neutral dealcoholized adhesive sealant, SIPC 2150 has excellent mechanical properties and excellent adhesive sealing performance for PC, PA plastic, concrete, wood, felt, EVA foam, metal (iron, aluminum, stainless steel) and other materials. Core advantages of SIPC 2150:Low…
