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
- Start at Sector 1 Plaza: Head up the escalators into the Executive Office suites.
- Check Cubicle Floors: Look specifically underneath the desks for beige and black vertical computer cases.
- Smash with Melee: Strike each PC tower 3–4 times with a blunt weapon until it breaks apart into components.
- 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.
