Engineered for high-density PCBA conformal protection, thermal dissipation, and airborne/tactical grade electromagnetic interference (EMI) sealing.
As smart devices—ranging from ultra-thin flagship smartphones, foldables, and AIoT wearables to high-frame-rate VR headsets—continue to push the boundaries of miniaturization, modern printed circuit boards (PCBs) face unprecedented electro-thermal challenges. Traditional separate shielding cans and passive dielectric conformal coatings consume vital board real estate and add unwanted assembly weight.
Electrically and thermally conductive epoxy formulations have emerged as a disruptive alternative. By combining thermosetting resin matrix chemistry with micro/nano-conductive filler networks (such as micron silver, silver-plated copper, and graphene structures), conductive epoxies serve dual critical roles: providing robust conformal hermetic insulation against moisture, sulfurization, and dust, while simultaneously acting as high-efficiency surface-level EMI shielding layers and localized thermal dissipators.
In high-frequency 5G mmWave and impending 6G communication architectures, high-density interconnections (HDI) suffer from severe electromagnetic crosstalk and rapid localized thermal accumulation around system-on-chip (SoC) and power management IC (PMIC) nodes. Precision-dispensed conductive epoxies provide comprehensive board-level conformal encapsulation with customizable dielectric-to-conductive gradient properties.
Songxi Technology has continuously advanced polymer synthesis to achieve ultra-low volume resistivity (<10⁻⁴ Ω·cm), superior adhesion to multi-layer FR4/polyimide flex substrates, and low coefficient of thermal expansion (CTE) matching silicon die characteristics. This guarantees zero micro-cracking and maintains signal integrity across rigorous thermal cycling from -40°C to 150°C.
Formulated with dense percolating silver particle networks, offering exceptional electromagnetic wave shielding effectiveness over broad broadband frequencies (100kHz to 40GHz).
Direct thermal bridges reduce localized junction temperatures of BGAs, MOSFETs, and processors, preventing thermal throttling in high-load consumer hardware.
Unsurpassed barrier performance against harsh salt spray, chemical corrosion, humid condensation, and mechanical vibration with verified UL 94 V-0 flame ratings.
Songxi Technology is a high-tech enterprise specializing in the R&D, production, and sales of electronic adhesives. Based on silicone, polyurethane, acrylic, and epoxy systems, we provide reliable bonding, sealing, and protection solutions for power electronics, optoelectronics, new energy, automotive, and aerospace industries.
We are committed to becoming a trusted provider of functional polymer material solutions for the electronics industry. Through continuous innovation and application development, we promote the localization of high-end electronic adhesives and help intelligent devices achieve greater stability and durability.
Delivering precision polymer adhesive systems and specialized thermal/conductive interface solutions globally.
Songxi's business covers three functional areas: adhesive & sealing, potting & protection, and thermal interface materials. Our product portfolio includes PCBA fixing adhesives, UV adhesives, sealants, thermal conductive potting compounds, thermal greases, pads, two-component thermal gels, EMI shielding sealants, and reactive hot melt adhesives.
Our products serve power batteries, photovoltaic modules, drones, automotive electronics, 5G communications, and LED lighting. We provide both standard products and customized solutions for applications such as BMS conformal coating, IGBT thermal filling, and power battery structural bonding, supported by extensive technical experience and application expertise.
Solving complex interconnection, protection, and shielding challenges across next-gen microelectronics.
In ultra-compact earwear and biometric health watches, component pitch is down to sub-millimeter scales. Conductive epoxy conformal coating provides selective ground shielding around high-gain RF receiver circuits, preventing audio interference and stray noise while simultaneously locking out moisture and sweat ingress.
Unmanned aerial vehicles (UAVs) and high-definition gimbal cameras require sustained high-frequency data transmission under intense mechanical vibration. Our polymer systems prevent partial electrical discharge, absorb structural stress, and prevent high-power transmission modules from overheating during continuous recording.
Led by a Ph.D. in Polymer Materials from Sichuan University, Songxi's R&D team has nearly twenty years of silicone application experience and has participated in over 100 product development projects. We maintain cooperation with research institutions including Chenguang Chemical Research Institute, Sichuan University, and Beijing Institute of Technology.
