Postless Deck – What is it in Vaping?

Postless Deck – Complete Glossary Entry

Definition

A Postless Deck is a type of rebuildable atomiser (RDA or RTA) build deck where the traditional positive and negative posts are removed. Instead, coil leads are inserted directly into small terminal holes or slots machined into the deck itself. This design maximises build space, simplifies installation, and improves airflow around the coil, making it ideal for both flavour-chasing and cloud-chasing vapers in Australia who use high-VG e-liquids and high-wattage Power Mode devices.

Technical Details

Postless decks work by routing the positive and negative connections beneath the deck surface; leads are secured with side-mounted grub screws (typically M3 or M4) or spring-loaded clamps. Most decks accept wires from 24-32 AWG and accommodate inner coil diameters between 2.5 mm and 4 mm. Terminal holes usually measure 2 mm–3 mm wide, allowing dual-coil builds up to 0.08 Ω–0.3 Ω when paired with high-drain 18650 or 21700 batteries. Common variations include semi-postless (one small central block) and floating-postless designs, both engineered for leak resistance in modern Pod System hybrids.

Usage & Tips

  • Trimming leads: Pre-cut each coil lead flush to the deck’s surface to prevent shorts.
  • Wicking: Use medium-density Cotton“>organic cotton; thin tails slightly for 70/30 VG/PG blends to avoid dry hits.
  • Common problem: Uneven heating—solution: gently pinch coils with ceramic tweezers while pulsing at 20-30 W.
  • Safety: Always check resistance on a Mod“>regulated mod before firing; Postless decks can reach low ohms quickly.

History & Context

Postless decks emerged around 2016 as vapers demanded larger build areas for exotic coils and higher Puff Count per session. Advanced Chinese manufacturers pioneered the style, and it quickly spread to mainstream Australian rebuildable markets, becoming a staple in high-end squonk RDAs and mesh-compatible RTAs.
