package import; package merge; A package import is "a directed relationship between an importing namespace and a package, indicating that the importing namespace adds the names of the members of the package to its own namespace." [2] By default, an unlabeled dependency between two packages is interpreted as a package import relationship. In ...

Cost is a factor in selection of integrated circuit packaging. Typically, an inexpensive plastic package can dissipate heat up to 2W, which is sufficient for many simple applications, though a similar ceramic package can dissipate up to 50W in the same scenario. [1] As the chips inside the package get smaller and faster, they also tend to get ...
1A1A44J5 - Unit 1, Assembly 1, Sub-Assembly 44, Jack 5 (J5 is a connector on a box referenced as A44) 1A1A45J333 - Unit 1, Assembly 1, Sub-Assembly 45, Jack 333 (J333 is a connector on a box referenced as A45) A cable connecting these two might be: 1A1W35 - In the assembly A1 is a cable called W35. Connectors on this cable would be designated:

JEITA (previously EIAJ, which term some vendors still use): Semiconductor Device Packages. (EIAJ Type II is 5.3 mm body width, and slightly thicker and longer than ...
Industrial and consumer packages other than boxes can also be subjected to compression testing: drum, pail, bottle, tub [1] etc. Package components are also evaluated for compression resistance. [2] It is usually a laboratory test involving a special machine, a compression tester, to apply controlled compression on a test specimen.
In this UML package diagram, package A depends on packages B and C. Package B in turn depends on package D, which depends on package C, which in turn depends on package B. The latter three dependencies create a cycle, which must be broken in order to adhere to the acyclic dependencies principle. [2]
