ProtelDxp components in the package is what it means, what is the package
The package here means that, in the drawing of schematic diagrams, you need to use different symbols, on behalf of different components, such as transistors, diodes, resistors, capacitors, and so on, in layman’s terms is that the circuit schematic diagrams that you see, the symbols are the schematic of the package; there is another package Is the PCB package, we do pcb, we need to install the components on the PCB board, then the components are size, size, polarity requirements, so the components of the PCB package reflects a size, size, polarity and other information. For example, the spacing of the openings, the size of the openings, the components of the external volume and so on. So it must be accurate, otherwise you do out of the PCB is not able to use, the component installation size is not right, it can not be installed, the aperture is too small, the component pins can not be inserted.
I don’t know if you understand what I’m saying!
What does schematic library, PCB library, package library each represent and what is the difference. ,,????
Package is the
look
of the components
done in accordance with the size and orientation of the components
Schematic library on the drawing of the schematic
components show the appearance of the components, such as resistors, capacitors, diodes in this SCH folder under the Miscellaneous
Devices. ddb
This
Library
PCB library is the library there is a component package, such as resistors in the PCB folder under the PCB
Footprints.ddb this library
What is the relationship between component packaging in pcb and component packaging in schematic?
Correspondingly, the schematic mainly reflects the pin connection relationship, and has nothing to do with the shape.
The PCB maps out the schematic connections and creates a definitive, visible physical package through the package name defined in the schematic.
What is the PCB package
pcb package is the actual electronic components, chips and other parameters (such as the size of the components, length and width, straight insertion, the patch, the size of the pads, the length and width of the pins, pin spacing, etc.) with a graphical representation, so that you can draw the pcb diagram when called.
Circuit board of various electronic components of a name, the main components of the pin size, spacing and other information, electronic components must be the same technical indicators.
Expanded Information
PCB, Chinese name for printed circuit board, also known as printed circuit board, is an important electronic components, is the electronic components of the support body, is the carrier of the electrical connection of electronic components. Because it is made using electronic printing technology, it is called “printed” circuit boards.
Electronic equipment using printed circuit boards, due to the consistency of similar printed circuit boards, thus avoiding the error of manual wiring, and electronic components can be automatically inserted or mounted, automatic soldering, automatic detection, to ensure the quality of the electronic equipment, improve labor productivity, reduce costs, and easy maintenance.
