November 9, 2026 ALPHA HiTech UP44-5311F UV Cure Encapsulant System
ALPHA HiTech UP44-5311F is a high-performance, one-component UV cure encapsulant system designed to enhance the attachment strength of solder joints by encapsulating chips and electronic components. Developed by MacDermid Alpha, this advanced material prevents IC devices from cracking or detaching under mechanical stress. Electronics manufacturers select ALPHA HiTech UP44-5311F for high-density printed circuit board (PCB) assemblies requiring rapid processing, excellent moisture protection, and simplified quality control.
Key Features and Benefits of ALPHA HiTech UP44-5311F
This UV-curable encapsulant epoxy delivers exceptional performance advantages tailored for high-speed SMT assembly lines:
- Fast UV Curing: Cures within seconds under UV radiation, significantly reducing cycle times and boosting production throughput.
- Fluorescent Inspection Property: Emits a blue fluorescent light when exposed to black light (UV light), allowing easy visual inspection of encapsulation coverage.
- Excellent Moisture Resistance: Protects delicate IC devices and solder interconnects against environmental humidity and contamination.
- High Mechanical Reliability: Reinforces component attachment to prevent cracking and drop failures under physical strain.
- Eco-Friendly Compliance: Halogen-free formulation fully compliant with RoHS Directive 2011/65/EU.
Application and UV Curing Guidelines
Dispensing ALPHA HiTech UP44-5311F is effectively executed at standard room temperature conditions. Because the material is light-sensitive, exposure to daylight, ambient UV light, and artificial lighting should be kept to a minimum. Syringes stored vertically at 1 to 10 °C (tip facing downward) must be thawed at room temperature for 2 hours before opening the cap. Once thawed, material should not be returned to its original container. Full property development is achieved by curing under a Metal Halide Lamp at 300 mW/cm² (365 nm wavelength) for a minimum of 10 seconds.
