Indium PicoShot® NC-5 Jetting Solder Paste

PicoShot NC-5M is a no-clean, halogen-free solder paste optimized for Mycronic MY600 / MY700 jetting systems. It is a jetting solder paste (type 5 powder) engineered for fine, precise deposits via jetting rather than stencil printing.

The standard alloy is SAC305, type-5 powder (≈ 85 % metal by weight). This gives good paste flow / coalescence performance while maintaining fine feature capability.

• Smallest dot volume: ~7.5 nl per dot at ~360 µm diameter.
• Jetting life (in syringe) greater than 8 hours under normal usage.
• Minimal satellite droplets and high positional (X,Y) accuracy.

• The flux is “no-clean” and meets IPC J-STD-004B with Amendment 1, ROL0 requirements.
• It’s halogen-free (meets relevant halogen limits per IEC / EN standards).

Recommended reflow parameters include:

• Preheat ramp: ~1.8-2.2 °C/s
• Peak temperature: ~235-245 °C
• Time above liquidus: ~30-40 seconds
• Total time from ambient to peak: ~2-3 minutes
  These ensure good soldering, avoid excessive flux burn-off, and promote proper powder coalescence to reduce defects like graping.

• Store refrigerated (preferably < -10 °C for unopened; 1-10 °C offers shorter shelf life).
• Syringes should be stored tip-down; let paste come to ambient temperature before use (at least 2 hours).
• Once opened / at room temperature, non-refrigerated syringes have a working or open-time limit (check datasheet).

• Unique oxidation barrier helps avoid graping (poor powder coalescence) during reflow.
• Clear residue with minimal flow-out; residue is benign.
• Reduces head-in-pillow (HIP) defects and reflow spatter compared to similar pastes.

• Because it’s designed for jetting, equipment must support precise jetting dispense (Mycronic MY series) and appropriate nozzle/ejectors.
• Dot size volumes are small – for large paste volumes, stencil or dispensing may still be needed.
• Ambient / syringe temperature control is more critical (viscosity, flow) than for printing paste.
• Open time (syringe life, idle time) is good but not indefinite; consistent usage or purge routines are important to maintain jet performance.
