RMA Rosin Core Solder Wire is the manufacturers’ choice for mildly activated, general-purpose rosin solder wire, ideal for military and aerospace applications. RMA rosin flux provides fast wetting and excellent tarnish/oxide removal, producing bright and shiny joints.

AIM’s cored solder wire for robotic soldering is engineered to promote fast thermal transfer and extend solder tip life. AIM’s solders allow high feed rates for point-to-point and drag soldering with excellent barrel fill.

AIM’s RMA258-15R Rosin-Based Solder Paste is specifically formulated to cater to the military, space, and aerospace markets. This solder paste efficiently combines the demands of high-reliability performance, meeting legacy specifications, with the capabilities of …

RMA is a mildly activated, general-purpose wire solder for use in applications requiring good activation. RMA cored wire is active enough for excellent tarnish or oxide removal, and will produce bright shiny solder joints.

CWSN63WRMAP3 .032 – Leaded Rosin Mildly Activated (RMA) Wire Solder Sn63Pb37 (63/37) 20 AWG Spool, 1 lb (454 g) from Amerway Inc. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

Superior No. 99 Type RMA liquid rosin flux is ideal for general purpose soldering of PCBs, wire, cable and semiconductors and hand-soldering applications. No. 99 can be used for automated and manual soldering applications, and meets all the requirements of Mil-F-14256C, Type RMA.

AMTECH RMA solder wire (WRMAP) is an RMA core solder, which conforms to ANSI/J-STD-004-006 and is designed for hand soldering and re-work applications. The core provides sufficient activity to solder successfully to bare copper and other hard to solder surfaces. The residue is a light amber color.

Rosin Mildly Activated (RMA) RMA flux consists of rosin, solvent, and a small amount of activator. Most RMA flux is fairly low in activity and best suited to easily solderable surfaces. IPC classification is usually ROL0, ROL1, ROM0, or ROM1. RMA flux residue is clear and soft. Most are non-corrosive and non-conductive.

AIM Solder rises to the occasion by offering an extensive array of tin-lead and lead-free RMA (rosin mildly activated) products tailored for the military and aerospace sector. With the know-how in the challenges that arise as lead-based components phase out, AIM provides both solutions and unwavering support.

Kester 285 RMA flux cored solder wire has a much greater fluxing ability than typical RMA fluxes and is comparable to fully activated RA fluxes allowing the use of an RMA level flux when process requirements stipulate without losing the ability to solder difficult assemblies.
