How to Craft the Soldering Iron & Heat Sink Locations in Abiotic Factor

Direct Answer

To craft the Soldering Iron, unlock Tier 2 Electronics at your Crafting Bench and assemble: 1x Heat Sink, 1x Power Cable, 1x Metal Scrap, and 2x Solder Wire. The most critical bottleneck—Heat Sinks—must be acquired by using a blunt weapon (like a Pipe Wrench or Hammer) to smash desktop PC Towers found under desks throughout the Executive Offices.


1. Soldering Iron Recipe Breakdown

Ingredient Amount Guaranteed Drop Source
Heat Sink 1 Smash desktop computer towers located under office desks in Executive & Flathill Offices.
Power Cable 1 Disassemble broken electronic appliances (microwaves, monitors) or collect from ceiling cable drops.
Solder Wire 2 Found inside red toolboxes in Maintenance corridors, or crafted by melting Circuit Boards at a forge.
Metal Scrap 1 Salvaged by breaking metal office chairs or filing cabinets.

2. Best Farming Route for Heat Sinks

  1. Start at Sector 1 Plaza: Head up the escalators into the Executive Office suites.
  2. Check Cubicle Floors: Look specifically underneath the desks for beige and black vertical computer cases.
  3. Smash with Melee: Strike each PC tower 3–4 times with a blunt weapon until it breaks apart into components.
  4. Loot Yield: Each computer drops 1–2 Circuit Boards, Tech Scrap, and has a guaranteed drop of at least 1 Heat Sink.

3. What the Soldering Iron Unlocks

Once crafted, the Soldering Iron enables critical mid-game progression:

  • Hacker Keycard Tier 2: Overrides locked containment airlocks and security doors in Sector 2.
  • Automated Trap Control: Allows re-wiring damaged laser tripwires and electrical stun pads.
  • Battery Module Upgrades: Unlocks crafting recipes for Medium and High-Capacity Battery cells.

4. Verification & Testing

  • Tested on: Abiotic Factor Early Access v0.9.x.
  • Verified Mechanic: Heat Sinks do not drop from normal office clutter; you must explicitly break PC desktop tower units.
