PCB packaging is to use various parameters of actual electronic components, chips, etc. (such as component size, length and width, in-line, patch, pad size, pin length and width, pin spacing, etc.) Graphical representation so that it can be called when drawing PCB diagrams.
Types of Component Packages
The package is mainly divided into DIP dual in-line and SMD chip package.
1. In-line component packaging
The pads of the in-line component package generally run through the entire circuit board, from the top layer, and the pins of the components are welded on the bottom layer.
2. SMD component packaging
SMD components mean that the pads are only attached to the top or bottom layer of the circuit board, and the soldering of components is carried out on the working level of the assembled components.
