Framed Staple Coil – What Is It & How It Works in Vaping?

Definition

A Framed Coil“>Staple Coil is an advanced rebuildable atomiser coil made by stacking multiple flat ribbon wires (the “staples”) between two thicker round wires (the “frames”), then wrapping the entire stack with a thin Clapton wrap. Designed for sub-ohmvaping, its large surface area delivers dense vapour and intense flavour while keeping ramp-up time low. Ideal for direct-lung (DL) vapers who enjoy high-wattage, cloud-rich sessions with Nicotine“>Freebase Nicotine e-liquids.

Technical Details

Construction & How It Works

  • Core: Typically 4–8 pieces of 0.1 mm × 0.3 mm Wire“>ribbon wire (Kanthal, Ni80 or SS316L) sandwiched between two 26–28 gauge round wires.
  • Wrap: A 36–40 gauge Clapton or Fused Clapton wrap locks the stack together, creating tiny grooves that hold e-liquid and maximise surface contact.
  • Resistance: Dual-coil sets usually read 0.1–0.2 Ω; single coils land around 0.2–0.3 Ω.

Variations

  • Staggered Framed Staple: Wrap wire is spaced for faster wicking.
  • Alien Framed Staple: Uses a de-cored Alien wrap for extra texture and flavour.

Usage & Tips

  • Wicking: Use medium-thick cotton—too thin causes flooding; too thick leads to dry hits.
  • Power: Start at 70 W for dual coils, adjust in 5 W steps to avoid burning cotton.
  • Installation: Align coil so air hits the flat sides; this boosts flavour and prevents hot legs.
  • Safety: Always pulse at low wattage to check for hot spots before wicking. Ensure resistance is within your mod’s limits.

History & Context

The Framed Staple Coil evolved in 2016 from the earlier Staple Coil, popularised by Australian and U.S. builders seeking denser vapour without the slow ramp-up of multi-core Claptons. Today it remains a staple (pun intended) in high-end RDAs and RTAs, prized by flavour chasers across Australia.
