Problematically, some manufacturers are developing metric 0201 components with dimensions of 0.25 mm × 0.125 mm (0.0098 in × 0.0049 in), [31] but the imperial 01005 name is already being used for the 0.4 mm × 0.2 mm (0.0157 in × 0.0079 in) package. These increasingly small sizes, especially 0201 and 01005, can sometimes be a challenge from ...
The component diagram extends the information given in a component notation element. One way of illustrating a component's provided and required interfaces is through a rectangular compartment attached to the component element. [3] Another accepted way of presenting the interfaces is the ball-and-socket graphic convention.
The integrated circuit package must resist physical breakage, keep out moisture, and also provide effective heat dissipation from the chip. Moreover, for RF applications, the package is commonly required to shield electromagnetic interference, that may either degrade the circuit performance or adversely affect neighboring circuits.
In diagrams, components are shown as a rectangle with the keyword «component». Optionally, in the right hand corner a component icon can be displayed. This is a rectangle with two smaller rectangles protruding from its left hand side. If the icon symbol is shown, the keyword «component» may be hidden as seen to the side. [1]
In component diagrams, the ball-and-socket graphic convention is used (implementors expose a ball or lollipop, whereas users show a socket). Realizations can only be shown on class or component diagrams. A realization is a relationship between classes, interfaces, components and packages that connects a client element with a supplier element.
In addition to the standard UML Dependency relationship, there are two special types of dependencies defined between packages: . 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."
UML Diagrams used to represent the development view include the Package diagram and the Component diagram. [2] Physical view: The physical view (aka the deployment view) depicts the system from a system engineer's point of view. It is concerned with the topology of software components on the physical layer as well as the physical connections ...
A thin-shrink small-outline package (TSSOP) is a rectangular, thin-body component. A TSSOP's leg count can range from 8 to 64. A TSSOP's leg count can range from 8 to 64. TSSOPs are particularly suited for gate drivers, controllers, wireless / RF , op-amps , logic , analog , ASICs , memory ( EPROM , E2PROM ), comparators and optoelectronics .
