If the term hermetic package is new to you, you are not alone! This is a common scenario for most people. A hermetic package is a package that uses a hermetic seal, which is entirely airtight, meaning nothing goes in and out of a hermetic package, including gas.
In any industry dealing with transporting and protecting physical objects, there will come a scenario that you will realize why you need a hermetic package. We have listed five reasons to convince you to use one before that scenario comes:
1. Maximum protection
Jobs in the fields of petroleum, geology, and oceanography require bringing electronic devices in extreme environments. A lot could go wrong if your equipment breaks during work. Vital data could be corrupted, directions back to your destination could be lost, or the actual material could burst, which means shelling out cash after.
Using a hermetic packaging in your sensors and other microelectronic items ensures that the items inside will not be affected by the environment outside. They usually have insulation resistance of at least ten gigaohms at 500 VDC.
2. End-to-end reliability
In more extreme fields like aerospace, electronic devices that are vital in the vessel’s operation are usually one of each. The reason why computer processors are stored inside hermetic packages is to keep the vessel runs smoothly from point A to B to C and so on.
Another need for total end-to-end reliability is in the hospital industry. Some machines are already five years old and is expected to aid a patient’s health. If something inside fails, then an unfortunate effect on the patient will happen. Hermetic packages allow devices to run for many years as if it was brand new.
Hermetic packages can tolerate pressure up to 40,000 psi. This is important if your work happens in unusually low or high altitude. Some examples include establishing sensors on top of a hill or below the ocean. This type of jobs in extreme environments require absolute fool-proof devices. After all, it is hard to go up a mountain or on the seabed regularly to replace a machine.
3. Save money
While having a hermetically packaged electronic device inside equipment could be costly, it will save money over time. Think of buying a machine that breaks every three years. Aside from spending tons of money, it is a waste in time and workforce to acquire the same machine.
4. Keep everyone safe
In case you hit your car, airbags will deploy to avoid your head and body hitting the steering wheel. Hermetic packages protect airbag sensors from deteriorating and will keep them 100% working until they are deployed.
Also, electric wiring in our house, office, malls, and other places are connected to switches or processors. A faulty switch caused by corrosion or insect infestation could shut down the power of a single establishment.
5. Innovation in your industry
A lot of breakthroughs in science and engineering happen in extreme environments where the place and its phenomena are needed to be observed. One needs capable equipment to collate data, observe patterns and outlier events, and document the scene. Every process requires a device that will not break until the information stored has been extracted or applied already.
Take, for example, submarine communications cable that transports digital data for our telephones, Internet, and computers. There are control boards or monitors below the oceans that accompany it that allows technicians to check whether it is working.
These cables are vital in a prosperous international trade of information and physical goods. A lot of lives are uplifted because they can connect with people from places far away from theirs.
Final Thoughts
Humans are becoming more and more connected to their digital lives for their personal and work life. Electronic devices in hermetic packages are one of the many reasons why our devices keep on working for our own good. It makes lives easier and safer.
