A hermetic seal is any type of sealing that makes a given object airtight (preventing the passage of air, oxygen, or other gases).The term originally applied to airtight glass containers but, as technology advanced, it applied to a larger category of materials, including metals, rubber, and plastics.
Flat no-lead is a near chip scale plastic encapsulated package made with a planar copper lead frame substrate. Perimeter lands on the package bottom provide electrical connections to the PCB . [ 1 ] Flat no-lead packages usually, but not always, include an exposed thermally conductive pad to improve heat transfer out of the IC (into the PCB).
Modified atmosphere/modified humidity (MA/MH) packaging is a technology used to preserve the quality of fresh produce so that it can be sold to markets far away from where it is grown, extend the marketing period, and to help suppliers reduce food waste within the cold chain. Commercial examples of MA/MH include sea freight of Galia and ...
A hermetic package allows essentially no gas exchange with the surroundings; such construction requires glass, ceramic or metal enclosures. This replica of the first laboratory transistor shows connecting leads and a glass jar for protection; packaging the device was critical to its success.
Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...
Nvidia's demand for advanced packaging from TSMC remains strong though the kind of technology it needs is changing, the U.S. AI chip giant's CEO Jensen Huang said on Thursday, after he was asked ...
