Superior Surface Protection for Reliable PCB Performance
HASL (Hot Air Solder Leveling) is a proven and cost-effective surface finish that provides excellent solderability and protection for printed circuit boards. This time-tested finishing process creates a durable, solderable surface that ensures reliable electrical connections and long-term performance.
Key Features
Exceptional Solderability – Creates an optimal surface for component attachment with excellent wetting properties and strong solder joint formation.
Cost-Effective Solution – Offers outstanding value as one of the most economical surface finish options without compromising quality or reliability.
Universal Compatibility – Works seamlessly with through-hole and surface-mount components, making it ideal for mixed-technology assemblies.
Proven Reliability – Decades of industry use have established HASL as a dependable choice for commercial and industrial applications.
Good Shelf Life – Maintains solderability for extended periods when properly stored, providing flexibility in manufacturing schedules.
Technical Specifications
- Coating Composition: Lead-free solder alloy (SAC305 or similar)
- Thickness: 1-40 micrometers typical
- Temperature Resistance: Suitable for standard reflow and wave soldering processes
- Surface Planarity: Adequate for most component types
- Storage Conditions: 12+ months shelf life in controlled environment
Ideal Applications
Perfect for consumer electronics, automotive components, industrial controls, telecommunications equipment, and general-purpose PCBs where cost-effectiveness and reliable soldering are priorities. Particularly well-suited for boards with larger pitch components and through-hole assemblies.
Note: For applications requiring ultra-fine pitch components or exceptional surface flatness, consider alternative finishes like ENIG or OSP.
HASL finish delivers dependable performance and excellent value, making it the go-to choice for high-volume production where proven reliability meets cost efficiency.
