TMYLOKU NC-559-ASM Soldering Flux Paste 10cc Syringe

Specifications

• Model: TMYLOKU NC-559-ASM
• Volume: 10cc 
• Type: No-Clean (NC) Rework Solder Paste
• Viscosity: High (Gel-like, does not run)
• Colour: Translucent / Amber
• Residue: Minimal, non-corrosive, clear residue
• Boiling Point: High temperature stability (won't burn off instantly at 350°C)
• Dispensing: Standard syringe (Plunger/Needle required).

Applications:

• Mobile Phone Repair: Essential for reballing PMICs, CPUs, and replacing charging ports.
• SMD Drag Soldering: Apply a line of flux across pins and drag your iron for bridge-free soldering of TQFP/SOP packages.
• Desoldering Aid: Mix with old lead-free solder to lower its melting point and make removal with wick easier.
• LED Strip Joining: Coats the copper pads to ensure instant adhesion of wires without overheating the LED backing.

Project Evolution

From "Rosin Core" to "Flux Master"

• The Bottleneck: Relying solely on the tiny amount of flux inside your solder wire isn't enough for rework. Once that flux burns off, the solder becomes clumpy and oxidizes.
• The Upgrade: Adding external NC-559-ASM flux keeps the solder active for longer. It allows you to reheat a joint multiple times without it turning into a dull gray spike.
• Unlock: This enables Hot Air Rework. You literally cannot replace chips with a hot air gun without external flux paste. This tube is your ticket to fixing laptops, phones, and complex PCBs.
• Effort Level: Beginner. Simply squeeze a small amount onto the area before heating.

Packing list: 1 x TMYLOKU NC-559-ASM Flux Paste (10cc Syringe)

Frequently Asked Questions (FAQ)

• What does "ASM" stand for in NC-559-ASM? It generally refers to the specific formulation series intended for Lead-Free and Leaded high-temp applications, though in import brands, it's often a generic model designator.
• Do I need to clean the board after using this? Technically no, it is "No-Clean" and non-corrosive. However, for a neat appearance and to prevent dust sticking to the sticky residue, cleaning with IPA is recommended.
• Is this conductive? No, the residue is non-conductive, making it safe for high-impedance circuits.
• Can I use this for plumbing soldering? Absolutely not. Plumbing flux is acid-based and will destroy electronics. This is rosin-based for electronics only.
• Does it come with a plunger and needle? Most 10cc syringes are sold as the "tube only" in bulk, but we often include a basic plunger. Please verify the main product image.
• How is this different from liquid flux? Paste stays in place. Liquid flux runs everywhere and evaporates quickly. Paste is better for holding BGA balls or SMD parts in place before reflow.
• Can I use this with lead-free solder? Yes, it works excellently with both leaded (60/40) and lead-free (SAC305) alloys.
• Why is the flux smoky? All rosin fluxes smoke when the activators burn off. Always use a fume extractor.
• What is the shelf life? Typically 12 months if stored in a cool place away from sunlight.
• Can this help remove old solder? Yes! Adding fresh flux to old, oxidized solder makes it melt faster and soak into desoldering wick much easier.
• Is this original Amtech? No, this is TMYLOKU brand, a high-quality compatible formulation that offers 90% of the performance at a fraction of the cost.
• Why is the plunger hard to push? The paste is viscous. Warm it slightly (hold in hand) to make it flow better.
• Can I use hot air with this? Yes, it is designed specifically for hot air rework profiles.
• Is it toxic? It contains rosin and chemicals that are irritants. Do not ingest and wash hands after use.
• Does it work on oxidized copper pads? Yes, the activators are designed to strip oxide layers from copper to ensure a good bond.
• Is it tacky (sticky)? Yes, it is very tacky, which helps hold small SMD resistors/capacitors in place before you solder them.
• Can I refill small syringes with this? Yes, this 10cc tube is often used to refill smaller dispensing needles.
• What color is the paste? It is a pale yellow/amber color.
• Does it leave white residue? High-quality 559 formulations leave a clear, glassy residue, not the white powder seen in cheap fluxes.
• Is this suitable for reballing gaming consoles (PS4/Xbox)? Yes, it is widely used for GPU/CPU reballing on consoles due to its high heat tolerance.
