Emissive armor ability reduces the amount of damage done by every shot that applies to the physical part of the ship; it does not come into effect until shield points are reduced to 0. Only the best emissive ability of all components on the ship is applied; there is no stacking. It does not matter whether the shot hits armor or not, whether it hits the EA component, or whether the emissive ability is on an "armor" component or an "internal" component.

Armor skipping damage types and special damage types (eg: Only Weapons) completely ignore emissive abilities. Stock crystalline shard cannons do not ignore emissive armor ability because it is on armor, but rather because the damage type is hard coded to ignore emissive ability.

Note that rules for triggering shield generation from damage and emissive ability are the same. It stacks though.

"E.g: The ship has 50 points of shield power and emissive armor capable of withstanding 30 points of damage and 20 points structure damage, a beam hist the vessel for 100 points of damage depleting the shield and hiting the armor. "

First, the hit applies to the shield layer. 50 points are done to shields, leaving 50 to apply to physical layer. Assuming the weapon is not a Skips Armor or a Skips Shields and Armor type, the damage is reduced to 20, no matter what component ends up being hit. If that 20 structure armor happens to be hit, the 20 damage will destroy it.
