Reliacore 15 Leaded Solder Wire

ALPHA® Reliacore 15 is the most effective RMA rosin core solder yet developed for hand soldering. The unique and powerful activation system of this core solder makes the flux exceptionally fast wetting when compared with other RMA core solders. Yet, Reliacore 15 meets all of the requirements of Federal Specification QQS-571E for Type RMA flux core solder.

Key Products Features & Benefits: 

  • Designed spcifically to meet military and aerospace requirements. 
  • Excellent solderability with high insulation values if the residues are left on. 
  • Cleaning is optional but can be carried out using solvent or semi aqueaous solutions. 
  • J-STD Classification: ROL1

FAQ's

Q - Is Alpha Reliacore 15 solder wire also available in a Lead Free Alloy?
A - No this solder wire only comes in 63/37 leaded alloy.

Q - I supply product to the military market is this wire suitable for this application?
A - Yes, this solder wire continues to be QPL listed for military applications and is a true RMA formulation.

Q - Can l easily wash off the residues after soldering?
A - The resiues will wash off in most solvent systems today or if you have water washing on site then you will need to add an sapponifier to the first stage to react with the rosins to turn them into a soap solution.

Q - Can the post soldering residues be left on the solder joint when finished?
A - Generally these flux reidues are benign after soldering. You should however be aware that the flux activation is classified under J Std as being moderate. If you require a product for more critical applications then you should consider Alpha Fluitin AS or Alpha Telecore Plus which is classified as having a low activation level.

Q - Health and safety have requested that l look at solder wires that are rosin and resin free do such products exist?
A - Alpha produces a solder wire that is called FT2002. This product contains no rosins or resins and is therefore deemed to be Colophony Free.
This solder wire comes in both Leaded 63/37 and Lead Free SAC305 in most common sizes.

Q - What is colophony and can it cause any health issues?
A - Colophony is a generic term for rosin, this is the sap or sticky substance that derives from pine and spruce trees. Its "stickiness" lends itself to being used in a wide range of products. We have traditionally used this product in fluxes due to these specific properties it can however lead to breathing difficulties and skin sensitivity. Always use fume filtration when soldering and change filters regularly.

Q - What is the difference between rosins and resins?
A - The terms are often used interchangeably, but rosin is a naturally occurring substance, and resin is either a modified rosin or completely synthetic material. Rosins are plant based products and are subject to more natural variation than resins, however resins are commonly used in newer flux formulations due to their more consistent performance.

Q - How does IPCJ-STD-004B flux classification work.
A - Flux designation has three components. The first two letters, RO, RE or OR, represent the basic chemical composition: rosin-based, resin-based or organic acid-based. The next component is flux designation, L, M or H, which describes the flux’s activity level as low, medium or high, and the final component, 0 or 1, this indicates if halides are present.
