# Amtech NC-559-ASM Flux Paste 100gm

Amtech NC-559-ASM Flux Paste 100gm is a globally recognized, high-performance “No-
Clean” tacky flux paste. It is specifically engineered for professional electronics
repair, including BGA (Ball Grid Array) reballing, SMD rework, and smartphone motherboard
repairs.

The following table provides a comprehensive technical and commercial description
of the product.

## Key Features Amtech NC-559-ASM Flux Paste 100gm

**1. No-Clean Chemistry**

The “No-Clean” designation means the residue left after the soldering process is
chemically inert, non-corrosive, and non-conductive. This eliminates the mechanical
necessity of cleaning the PCB after rework, which is critical for high-density components
where cleaners might get trapped.

**2. Excellent Wetting and Thermal Stability**

It provides superior wetting properties, allowing solder to flow smoothly over pads
and component leads. The flux remains stable under high temperatures, preventing
premature “drying out” during extended hot air rework or infrared reflow cycles.

**3. High Viscosity and “Tackiness”**

The paste has a high “tacky” consistency, which serves a functional purpose: it 
holds small SMD components and BGA spheres in place before the heat is applied. 
This prevents components from shifting due to air pressure from a hot air station.

**4. Clear Residue with UV Tracer**

The residue remains clear and transparent after heating, allowing for easy visual
inspection of the solder joints. The inclusion of a UV tracer allows quality control
teams to use UV light to ensure the flux was applied and distributed correctly across
the board.

## Primary Applications

 * **BGA Reballing:** Ideal for attaching solder spheres to BGA chips (CPUs, GPUs,
   EMMC).
 * **Smartphone & Laptop Repair:** Used for micro-soldering tasks on densely packed
   motherboards.
 * **SMD/SMT Rework:** Perfect for removing and replacing surface-mount devices 
   like resistors, capacitors, and ICs.
 * **Flip-Chip Attachment:** Suitable for high-precision industrial semiconductor
   assembly.

## Amtech NC-559-ASM Flux Paste 100gm Usage and Handling Guidelines

 * **Application:** Can be applied via syringe, stencil printing, or manually with
   a precision tool.
 * **Cleaning (Optional):** While cleaning is not required, if a pristine aesthetic
   is needed, residues can be removed using Isopropyl Alcohol (IPA) or specialized
   aqueous flux cleaners.
 * **Safety:** Always use in a well-ventilated area. While low-smoke, the fumes 
   from any soldering process should be extracted using a fume extractor.
