RMA-LF-PRO-305 - Sn96.5.Ag3.Cu0.5 lead-free high activity rosin mildly activated solder paste 3% silver (ROM1)
- High activity Sn96.5Ag3.0Cu0.5 soldering paste for SMD assemblies. Small syringe container for repair/rework, prototyping. Liquidus/solidus point - 219ºC. Powder composition: 96.5% Tin, 3% Silver, 0.5% Copper. Made using RMA-LF-PRO-TF soldering tacky paste flux.
- High-quality lead-free SAC305 solder powder made using virgin raw materials. Consistently shaped microscopic granules evenly suspended in a golden body of a rich in solids thick RMA soldering tacky flux. Activates immediately, demonstrating professional industrial wetting on most PCB finishes, smooth dispensing, quick and efficient soldering/desoldering and effortless cleaning with IPA, Hot Air or vapor degreaser.
- RMA-LF-PRO solder paste can be applied as a BGA alternative or as a liquid solder for PCB repair and rework - delivers instant bridge-free reflow with Hot Air. Quick response to a solder iron. Essential for lead-free rework/repair, BGA and SMD assembly.
- Light amber residue. Contains QC-Aid special optical tracer glowing in UV for immediate visual PCB contamination inspection. QC-Aid - Everyone Can QC!
- Factory-made in the USA using certified conflict-free solder powder traced back to original alloy smelters. Supplied in an industrial air-syringes designed for pneumatic dispensers, supplemented with FREE snuggly fitting manual plunger and blunt dispensing tips.

Stencil Cleaning
Stencil Cleaning
No-clean solder paste that can be left on the board for many SMT assemblies. For applications requiring cleaning, the paste can be cleaned using commercial residue removers.
Automated cleaning systems for both stencil and misprinted boards. Manual cleaning using isopropyl alcohol (IPA), co-solvents and/or ultrasonic scrubbers, vapor degreaser.
Do you make this paste untraceable - without QCA?
Do you make this paste untraceable - without QCA?
UV light is for optional for QC certification only - not required for operating the paste.
However, this material is also available untraceable - without QC-Aid™, meaning no specific optical UV-tracer has been deployed. Contact us for the MPN (Manufacturing Part Number) without UV-tracer.
Storage and Handling
Storage and Handling
To obtain the maximum shelf life STIRRI Soldering Paste & Liquid Solder™ should be stored in a refrigerator between 3-8°C (37-46°F). Unopened solder paste stored at room temperature, 25°C (77°F). Syringes and cartridges should be stored in the refrigerator vertically, dispensing tip pointing down.
Allow 4-8 hours for solder paste to reach optimal operating temperature of 20-25°C (68-77°F). To avoid condensation inside solder paste - keep solder paste container sealed while warming the solder paste to operating temperature, otherwise moisture may end up inside the container and contaminate solder paste!
NEVER FREEZE SOLDER PASTE!
