Basic electronics components

While electronic components process information in form of electrical signals, a printed circuit board is the skeletal structure on which the electronic components are mounted and soldered to hold them together and provide pathways for information to flow between components through PCB traces.


Kitting guidelines

Kitting in PCB assembly is driven by growing customization and usage of component variants essential for assembly. Following the specific Sierra Circuits kitting guidelines is crucial to obtain high-quality products at competitive pricing.


How to design footprints

Footprints depict the land pattern of a component on a bare PCB. It is the region in which the component will be soldered. It is basically the physical interface between the board and the component.


Schematic design rules

A schematic diagram is a fundamental two-dimensional circuit representation showing the connectivity between different electrical components in a circuit board. Each of these components has its footprint that defines the terminal geometry of the component. A schematic can be an extremely valuable troubleshooting tool as it traces out the connections in the circuit.


PCB via design

Vias are tiny conductive paths that establish electrical connection between the different PCB layers. Learn more about PCB via design. Learn more about PCB via design by scrolling down below.


PCB manufacturing overview

PCB manufacturing involves converting design files which include Gerbers and netlists into a physical circuit board on which components can be placed and soldered.


Annular ring size

When an annular ring is less than the specified width, the attachment of the component might be affected. This might lead to a pad breakout that refers to a condition of an annular ring being absent or of zero width.


PCB layout rules

Drawing a schematic of a circuit is the initial stage in PCB design. CAD software is then used to convert this block diagram into schematic drawings. A schematic is made up of component symbols and the connections that connect them. These nets will become copper traces on the circuit board.
