2. Moisture sensitivity level - Wikipedia

   en.wikipedia.org/wiki/Moisture_sensitivity_level

   Components such as thin fine-pitch devices and ball grid arrays could be damaged during SMT reflow when moisture trapped inside the component expands. The expansion of trapped moisture can result in internal separation (delamination) of the plastic from the die or lead-frame, wire bond damage, die damage, and internal cracks. Most of this ...

3. Antistatic bag - Wikipedia

   en.wikipedia.org/wiki/Antistatic_bag

   An antistatic bag is a bag used for storing electronic components, which are prone to damage caused by electrostatic discharge (ESD). These bags are usually plastic polyethylene terephthalate (PET) and have a distinctive color (silvery for metallised film , pink or black for polyethylene ).

4. Moisture vapor transmission rate - Wikipedia

   en.wikipedia.org/wiki/Moisture_vapor...

   The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs , need an encapsulation with low values of WVTR to guarantee the same performances over the ...

5. Polychlorotrifluoroethylene - Wikipedia

   en.wikipedia.org/wiki/Polychlorotrifluoroethylene

   PCTFE films are used as a protective layer against moisture. These include: moisture barrier in pharmaceutical blister packaging, water-vapour barrier for protecting phosphor coatings in electroluminescent lamps (the phosphor chemicals are sensitive to moisture), protection of liquid-crystal display (LCD) panels, which are sensitive to moisture,

6. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   Conformal coatings are used to protect electronic components from possible environmental exposure; they allow moisture to escape but protect against contamination. More recently, conformal coatings are being used to reduce the formation of whiskers [2] and to prevent current bleed between closely positioned components.

7. Hermetic seal - Wikipedia

   en.wikipedia.org/wiki/Hermetic_seal

   Airtight implies both waterproof and vapor-proof. Applications for hermetic sealing include semiconductor electronics, thermostats, optical devices, MEMS, and switches. Electrical or electronic parts may be hermetic sealed to secure against water vapor and foreign bodies to maintain proper functioning and reliability.
