SALT AIR
PROTOCOL

When the Puget Sound humidity hits 97%, copper chloride forms at 0.03mm²/min on exposed PCB traces. This isn't theory. This is the corrosion vector that killed my first rig at 0400 hours, July 14th, 2025.

We don't pray for dry days. We engineer for the wet ones.

HUMIDITY THRESHOLD

97%

Critical saturation point at Puget Sound shoreline. Above this, dielectric breakdown occurs within 4.2 hours on unprotected connectors.

CORROSION RATE

0.03mm²/min

Copper chloride propagation velocity measured during First Slip event. Exponential growth after hour 3.

DIELECTRIC COATING

12μm

Minimum conformal coating thickness required for 10-year lifecycle in Olympic Peninsula climate zone.

THERMAL DRIFT

+18°C/hr

GPU junction temperature spike when cooling fins clog with salt particulate. Point of catastrophic failure.

CORROSION TIMELINE // FIRST SLIP

INITIATION PHASE

0400 // Day 0

Humidity gauge reads 97%. Salt aerosol concentration peaks at 12mg/m³. First micro-fracture detected in PCB trace insulation layer.

ACCELERATION PHASE

0723 // Hour 3.375

Copper chloride dendrites bridge adjacent traces. Leakage current exceeds 2.4mA. System begins erratic reboot cycles.

CATASTROPHE POINT

0947 // Hour 5.78

Main power rail shorts to chassis ground. Thermal runaway initiates. GPU junction reaches 214°C before emergency cutoff.

RECOVERY WINDOW

1130 // Hour 7.5

Manual intervention possible. Isolation protocol engaged. Salvage rate: 68% of original functionality.

While the galaxy chases golden seams and beautiful scars, I'm measuring the exact voltage threshold where copper chloride kills your motherboard. This is the difference between a story and a solution.
