How Static Shielding Bags Work
One of the most common problems for any professional or hobbyist in the electronics industry is static discharge.
Whether it comes from an electronic component itself or from an outside source, these static charges have the potential to disrupt
and
irreversibly damage your items.
While you may be able to control what
kind of materials come
near your goods while you work with them, what happens during storage and shipping is a guessing game that you
can't always regulate.
To prevent harmful electrostatic charges at any point of the supply chain process, you can enlist the help of static shielding bags
and other
anti-static
packaging supplies
.
How Electrostatic Charges Occur
At this point,
you may b
e wondering just how and why electrostatic charges
happen
and why they damage electronic components
.
To boil it down to the basics,
these instances occur
when two
objects rub against one another
. As this contact happens,
they can create an imbalance of positive and negative charges
,
which
are frequently referred to as friction, and that friction will
then build up on the surface of one or both objects until
it is
released
. The friction release
is what we refer to as an electrostatic charge or static discharge.
This
is
especially problematic for electronic parts and devices, as their sensitive components can be fried by a static charge, rendering them broken and completely
worthless
.
What are Static Shielding Bags?
Some electronics are so sensitive to charges that even the static buildup on your own hands can permanently damage them.
Static shielding bags,
which are
sometimes
also
called Faraday bags or ESD shielding bags,
were developed in order to protect
these
valuable electronic devices and components from
all levels of static discharge.
These helpful poly bags consist of multiple layers that all work together to protect your items.
Essentially, they act sort of like a small Faraday cage (hence the name Faraday bags) that offers outstanding security to any sensitive or valuable electronic components you place inside. Let’s take a look at how static shielding bags work and how they
are constructed:
Layer 1:
your electronics, but it also does not allow any static buildup to occur. Polyethylene plastic cannot create or hold aThe inner layer of a Faraday bag is made of durable polyethylene plastic. Not only does this layer act as a soft surface that makes direct contact withyour electronics, but it also does not allow any static buildup to occur. Polyethylene plastic cannot create or hold a
ny sort of electric charge, which means that harmful static buildups won’t happen inside of it.
Layer 2:
The middle layer of any static shielding bag is constructed from aluminum. This material is what provides the actual shield against external static discharges that would otherwise pass through the bag and destroy the part inside.
This is because the aluminum acts as a conductor that will take the discharge and ground them, keeping your electronics out of harm’s way.
Layer 3:
The final outer layer of
the black static shielding bag is polyester
plastic with a dissipative coating to help prevent static buildups
, just like the inner layer.
However, this
outer layer protects both the product inside the Faraday bag and
the
middle aluminum l
ayer from electrostatic charges.
Static shielding bags are an essential tool for packaging and storing any kind of sensitive electronics, but we commonly see them used to protect
items like circuit boards, memory cards, processors, and more.
Most often, these bags are a black or metallic black color, which makes them more easily recognizable.
One important aspect of these versatile tools to make sure to note is that in order to work correctly and effectively, Faraday bags must be properly and tightly sealed with no punctures
, rips, or tears
.
Static Shielding Bags vs. Anti-Static Bags
When seeking out protective packaging that is specifically designed for electronics, many businesses also use a
product called anti-static bags
. These bags are very similar to Faraday bags in that they
are
constructed
out of
polye
thylene
plastic with
dissipative coatings to
prevent static buildup within the bag itself. However, unlike static shielding bags, they do not have an aluminum layer to act as a conductor and safeguard the product
against external static charges. Anti-static bags are of
ten characterized by their pink color and are also available in other packaging materials like bubble film or foam. They tend to cost less than their static shielding counterparts, but do not offer the same level of protection.
