PCB dam sealing and potting – guardians of electronic components

2025-09-18

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.

SIPC 9030 RTV Silicone Sealant: The Best Choice and Technical Advantages of Automotive Connector Potting

2025-07-11

In modern automotive and electronic devices, connectors play an important role as a key component in achieving signal transmission and current connectivity between electronic components. With the continuous development of automotive intelligence and electronics, the performance and reliability of automotive connectors are also becoming increasingly important. Connector FillingWhat is connector sealing?Connector sealing is a process that uses special adhesives or sealing materials to fill the connector inside. The main purpose of sealing is to form a protective film inside the connector to prevent the external environment (such as moisture, dust, corrosive substances, etc.) from entering the connector, thus preventing possible short circuits, corrosion or other damage.Typically, the sealant used in connector sealing has a high degree of adhesion and waterproof, dustproof, heat-resistant and other characteristics, so as to ensure that the connector can operate stably in the automotive, aviation, industrial equipment and other environments for a long time.Connector FillingWhy do connectors need to be sealed? Waterproof and moisture-proof Connectors are often exposed to moisture and moisture, causing short circuits or corrosion. Sealing effectively prevents moisture from entering the connector and keeps the internal electrical components dry, thus avoiding failure caused by moisture.Anti-vibration and impactConnectors in automotive or industrial equipment are often subjected to vibration and shock. Sealing provides an elastic protective layer that reduces mechanical stress and prevents the connector from loosening or breaking due to vibration, ensuring stable signal transmission.High and low temperature resistanceConnectors are prone to damage at extreme temperatures, and temperature differences cause metal components to expand or shrink, affecting contact performance. Sealing technology ensures that the connector remains stable in the temperature range of -60 ° C to 260 ° C, avoiding failure due to temperature changes. Improved electrical insulation performanceThe electrical contacts of the connectors are susceptible to current fluctuations. The seal provides excellent electrical…
