Amtech RMA-223 - Solder Paste (10ml)

Amtech RMA-223

The Amtech RMA-223 is a high-performance solder paste designed for precision electronic assembly and rework. This rosin mildly active (RMA) solder paste is formulated to provide exceptional print definition and excellent wetting on most board finishes, making it ideal for surface mount technology (SMT) applications.

Key Features:

• ROL0 Flux Classification: The RMA-223 solder paste is classified as ROL0, indicating that it is both rosin-based and has low activity without cleaning.
• Exceptional Print Definition: It offers outstanding print definition, crucial for achieving precise soldering results.
• Excellent Wetting: The paste provides excellent wetting properties, ensuring good solder flow and strong, reliable solder joints.
• Low Voiding: The formulation minimizes voiding, a significant issue in solder joint reliability.
• Long Stencil Life: With a long stencil life, it allows for extended use without the need for frequent replacement or cleaning.
• Wide Process Window: The paste has a wide process window, accommodating various reflow profiles and manufacturing conditions.

Technical Specifications:

• Alloy Composition: Available in multiple alloys, including Sn63/Pb37, Sn62/Pb36/Ag2, and others, to suit different melting temperature requirements.
• Viscosity: Tailored for both printing and dispensing applications, ensuring smooth application and adherence to the stencil or syringe dispensing patterns.
• Particle Size Distribution: Solder powder within the paste has a specific particle size distribution to meet pitch requirements for different SMT applications.
• Flux Content: Optimized for the best performance in printing applications and dispensing applications.
• Packaging: Available in various options, including jars, cartridges, and syringes, to suit different operational needs.

Advantages:

• REACH Compliant: The RMA-223 solder paste is REACH compliant, meeting the European Union’s strict chemical safety regulations.
• Compatible with Enclosed Print Heads: It is compatible with enclosed print heads, beneficial for automated SMT lines.
• Print & Dispense Grade: Available in both print and dispense grades, providing versatility for different application methods.

The Amtech RMA-223 solder paste is a reliable choice for those seeking high-quality soldering results in SMT assemblies. Its combination of excellent print definition, wetting properties, and low voiding makes it a go-to solution for professionals in the electronics manufacturing industry. Please note that while the RMA-223 can be left on the board for many SMT assemblies, certain applications requiring cleaning can utilize flux residue removers for post-process cleaning.
