When humidity hits 97%, copper chloride crystallizes on your traces. This is the vector. This is the rebuild. This is how you survive the storm.
SCENE ONE: Four hundred hours. Olympia shoreline. The humidity gauge reads ninety-seven percent. This is not a warning. This is the moment the circuit dies. I learned this at the workbench, soldering iron still warm, watching the corrosion eat a trace wider than a human hair.
SCENE TWO: Copper chloride crystallization. Trace width point-one-five millimeters. Corrosion rate two point three micrometers per day. The dielectric breaches in seventy-two hours. This vector is not theoretical. I mapped it myself, under the salt spray of the Strait of Juan de Fuca.
SCENE THREE: Rebuild sequence. Phase one: ion flush. Phase two: dielectric regrowth to twelve micrometer specification. Phase three: conformal coat. This is not hope. This is protocol. Written in blood, tested in storms.
SCENE FOUR: Sealed. Salt-proof. Storm-ready. The next ninety-seven percent will not kill us. Because this time, we remember.

ION FLUSH
Remove active chloride ions from trace surfaces using distilled water rinse at 45°C. Dry with nitrogen blow-off at 20psi.
DIELECTRIC REGROWTH
Apply UV-cured epoxy resin to achieve 12μm minimum thickness. Cure at 80°C for 18 minutes under inert atmosphere.
CONFORMAL COAT
Silicone elastomer barrier (Shore A 40 hardness). Spray application at 0.3mm pass thickness. Bake at 60°C for 30 minutes.
