Amtech Stirri- Genuine Advanced Aerospace & military Grade Industrial Products.

RMA Sn63Pb37 Type-4 eutectic solder paste 20-38 micron powder grain size 87% load.
Used with 12-16mil high-pitch SMT assemblies in space exploration and defence contractor’s specs.
Small syringe container for repair/rework, and prototyping.
Liquidus/solidus point – 183C (Eutectic).
Powder composition: 63% Tin, 37% Lead.
Contains 13% RMA-TF no-clean soldering tacky paste flux

High-quality leaded Sn/Pb 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 or Hot Air

RMA 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 leaded rework/repair, solar exploration, unmanned flying devices and Sn63Pb37 military tech

Clear residue is not corrosive and can be left on PCB, removed with isopropanol, and cleaned in ultrasonic or vapour degreasers.
Contains QC-Aid special optical tracer glowing in UV for immediate visual PCB contamination inspection – easy to detect using UV/blacklight light and easy to clean using Isopropanol or any industrial solvent cleaner – paste will glow in UV highlighting affected areas.
QC-Aid – Everyone Can QC!

Factory-made in the USA using certified conflict-free solder powder traced back to original alloy smelters.

Cleaning

No-clean solder paste can be left on the board for many SMT assemblies.
For applications requiring cleaning, the paste can be cleaned using commercial flux residue removers.

Storage

Solder paste should be stored between 3-8°C (37-46°F) to obtain the maximum refrigerated shelf life of six months.
Unopened solder paste stored at room temperature, 25°C (77°F) will have a one-month shelf life.
Syringes and cartridges should be stored vertically in the refrigerator with the dispensing tip down.

Allow 4-8 hours for the solder paste to reach an optimal operating temperature of 20-25°C (68-77°F).
Keep the solder paste container sealed while warming the solder paste to operating temperature.

Never Freeze Solder Paste!
