What Are Hermetic Feedthroughs?

Hermetic Feedthroughs

Hermetic feedthroughs have been commercially available for a while now and are often associated with use within industries such as electronics, automotive, and even aerospace and defense applications. Yet, while they grow popular because of the resiliency and electrical integrity that they impart to certain elements, you may still be left to wonder about the details behind this important vessel component.

Before you examine what hermetic feedthroughs are, however, it is important to be familiar with the basics.

What is a feedthrough?

In between two circuit boards (or an enclosure) stands a connector known as a feedthrough. This kind of connector is capable of acting as an electrical conductor for certain environmental barriers or enclosures.  Depending on the kind, a feedthrough can transmit low current or low voltage electrical signals (instrumentation feedthroughs) or high current or high voltage ones (power feedthroughs).

What makes a feedthrough hermetic?

A hermetic feedthrough is an electrical conductor that is armed with a hermetic sealing. This kind of connector is completely sealed and made to be airtight.

Hermetic sealing of feedthroughs is done to protect the feedthrough from harsh environments and other forms of extreme and damaging conditions that may surround it. Things like oxygen, moisture, and humidity are kept out as they would otherwise cause the sealed electric components to malfunction once they seep in.

The hermetic sealing used for hermetic feedthroughs can also vary in constitution and function. For example, some are made out of epoxy resins (epoxy hermetic seals) which are effective for sealing off some gases and even certain types of fluids.

On the other hand, some are those that utilize glass-to-metal hermetic sealing technology (such as the ones used in vacuum tubes). They can withstand higher pressure and higher temperature (as opposed to epoxy hermetic seals that operate on lower temperature ranges.

Effects of Low Staff Turnover in a Business

Posted on by Raina

Staff or employee turnover refers to the number of employees who leave a certain company and are substituted for new ones.
Back when I worked in Groupon Dubai, we would lose at least one employee a week. It was scary knowing that you could be let go or even worse, forced to quit so easily! Management must have thought it instilled an environment of hard work in the workforce, but was this high staff turnover rather beneficial or destructive to the overall team morale? Continue reading to see some of the effects of high and low staff turnover.

Fear Versus Security

Having a high employee turnover in a business instills fear in the employees who work there and reduces their overall morale. They know that it’s easy for the organisation to replace them if need be.
On the other hand, low staff turnover means that the company values its employees and appreciates their work, which in turn makes workers more secure about their jobs and more productive.

High Cost Of High Turnover

High staff turnover means higher costs for a business. As my boss once explained to me, a company spends a lot of money hiring and training new staff. Companies with low staff turnover spend more time interviewing potential employees to make sure they’re exactly right for the positions they are interviewing for before making a final decision.

Achieving A Low Turnover

So how does a company achieve and maintain a low staff turnover? Studies show that decent salaries and better communication between managers and its employees greatly reduces employee turnover by enabling employees to work for longer periods of time at an organization. Finally, being able to progress and get promoted in a company also reduces employee turnover.

To put it in a nutshell, it makes sense for companies to have a low staff turnover for several reasons, including lower costs, better employee morale, and higher productivity.

How What You’re Wearing Can Improve Your Confidence

Posted on by Raina

Although it might appear to be shallow, the way we dress creates an impression about who we are and where we want to be. Since people tend to judge us (deliberately or not) anyways, to a certain extent in terms of what we look like, why not dress as though you’re prepared for a promotion? Dressing well, be that as it may, doesn’t really mean wearing a suit and tie every day. Sometimes, unpretentious yet subtle garments can make a great impression, particularly on people like your managers.

Your clothes won’t hold you down anymore if you learn how to wear the right pieces of clothing. Yes, you read that right, the right clothes can have a major impact on your anxiety level as well as your self-confidence. Wearing casual and boring clothes all the time can directly reduce your confidence and increase your anxiety.

I personally recommend buying the best-quality shoes you can afford, and always picking quality over quantity. Furthermore, get rid of your Bic and purchase a quality pen. It doesn’t need to be expensive, however it should look elegant. Get rid of your rusty old wallet or cardholder and invest in a new one! People barely see the new wallet I purchased since my fiance always insists on paying when we go out together, but the fact that it’s elegant and chic makes me feel good!

When you wear clothes that you look good in, they will surely boost your confidence and you will just feel great wearing them. At that time, you will completely forget about anxiety, all you can think about will be the outfit you are wearing and how good you look in it. Dress your children well too, having attention is nice from time to time.

Because let’s be honest, anxiety is a product of reduced self-confidence that people never had or lost due to an unpleasant event or trauma. So, make sure you choose a comfortable and modern style, and colors that will make you feel confident about yourself.
