Selecting BMS Conformal Coatings & CCS Fixing Adhesives: FPC, PI & Shadow Cure Model Recommendations

Adhesives for BMS and battery integrated busbars shall be selected according to circuit board moisture resistance, FPC & PI bonding, solder joint reinforcement, UV curing speed and shadow-area curing requirements. For fast conformal coating of BMS circuit boards, Elaplus UV Coating 9060M is available for evaluation; UV 1013 is suitable for integrated busbar and solder joint reinforcement; UV 1034 is the choice for FPC-to-PI bonding; UV SI 3301 delivers wide-temperature-range performance, flexible protection and supplementary curing in shadow areas. Why Do BMS Require Conformal Coating Protection? The BMS undertakes collection of cell voltage, temperature and current data. Once circuit corrosion, loose solder joints or reduced insulation occur, judgment of battery status may be adversely affected. Common risks for BMS and integrated busbars include: Therefore, BMS protection is not merely applying a layer of conformal coating. It also covers FPC fixation, integrated busbar reinforcement and stress buffering for solder joints. Recommended Grades for BMS Circuit Board Conformal Coating UV Coating 9060M: UV & Moisture Dual-Cure Conformal Coating UV Coating 9060M is a low-viscosity UV & moisture dual-cure material. Its viscosity specified in the datasheet is approximately 190 cps, with operating temperature ranging from -65℃ to 125℃. Suitable applications: Exposed areas achieve fast UV curing; component bottoms and shaded regions complete secondary curing via moisture. Recommended Grades for Integrated Busbar Reinforcement UV 1013: Fast UV Cure Reinforcement Adhesive UV 1013 is a one-component UV curable adhesive with viscosity around 20,000 cP. Typical curing time under 365 nm UV light is approx. 10 seconds as specified in the datasheet. Recommended applications: Recommended Grades for FPC & PI Bonding UV 1034: Adhesive Specially for FPC & PI Bonding UV 1034 is a UV curable adhesive featuring good adhesion compatibility with FPC and PI substrates. FPC Solder Joint Fixation Recommended applications: Recommended Grades for Wide-Temperature-Range…
