Static Shielding Bags and specialised packaging for the Electronics Industry
Packaging protects electronic items from physical and general environmental damage during manufacture, transportation, and storage. What most electronics providers don't know is that some types of packaging may also harm static sensitive electronic items by allowing the accumulation or the discharge of static electricity. For example: Polyethylene bags provide direct physical protection for contained items but also accumulate potentially damaging amounts of static electricity.
There are two main types of Static Shielding bags available to the electronics industry: buried metal and 'metal-out'. Buried metal bags are the most commonly used type because they are usually more durable and more cost effective. Buried metal static shielding bags are made from a multi-layer laminated film. Two polymeric plastic layers encase a conductive aluminium layer and this metallic layer provides a protective Faraday cage around the bag contents to shield if from ElectroStatic Discharge's (ESD's).
The fact that these bags are designed to pass electrostatic charges around the bag and away from the bag contents make it the ideal packaging for ESD sensitive electronic devices. Metal-out static shielding bags are constructed using a similar principle as it's 'buried metal' counterpart with the exception of the metal layer being closer to the outer layer of the bag. This results in the bag having lower ElectroStatic resistance readings which can be useful in some applications (this is why it is important to speak to your packaging manufacturer about your specific electronic needs).
Advanced packaging companies use the latest production methods to ensure that the outermost layer of these bags is both static dissipative and puncture and abrasion resistive. Most modern buried metal static shielding bags can be used several times. In some cases a Moisture Vapour Barrier (MVB) shielding bag will be required for added protection against outside elements.
The sensitivity of the component being packaged and the estimated storage period are both elements to be considered when talking to your specialised packaging provider. Shielding bags are used not only because they prevent ESD (ElectroStatic Discharge) sensitive components from charging up via a field induction but also because they minimise the potential damage from the sealed item coming into contact with an ElectroStatic Discharge Event. The Electrostatic Discharge Association (ESDA) provides information on international standards used to package electronic components.

In tig welding a flux is sometimes needed because the inert gas cannot fully shield the molten metal. T or F?
Is this answer true or false?
FALSE
Because the whole idea of TIG Welding is to shield the molten metal with an inert gas so that a flux WON'T have to be used.
According to Wikipedia: http://en.wikipedia.org/wiki/Tig_welding
"Gas tungsten arc welding (GTAW), also known as tungsten inert gas (TIG) welding, is an arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma."
