PCB Footprint Creation in Allegro, Altium Designer & KiCad

PCB Footprint Creation in Allegro, Altium Designer & KiCad

Components that need to be assembled on a PCB will have designated locations according to the design. Footprint is the arrangement of plated pads where a component is supposed to be soldered. It is also called the land/pad pattern and resembles the physical dimensions...

Key Aspects of DFM for HDI PCBs

Key Aspects of DFM for HDI PCBs

Design for manufacturability (DFM) for HDI PCBs refers to designing layouts that reduce the errors associated with fabrication and assembly. Before fabrication, the manufacturer will run a set of checks on the board files (Gerbers or ODB++) to confirm that these files...

Top Missing Information When Requesting a PCB Quote

Top Missing Information When Requesting a PCB Quote

Once a circuit board designer prepares the design, the next step is to find a manufacturer to transform it into a finished product. To get the board manufactured, an estimate or a PCB quote needs to be placed. The main intention is to fabricate and assemble a board...

Impedance Matching in HDI PCB Design

Impedance Matching in HDI PCB Design

Impedance matching is the way of configuring the input impedance of a load or the output impedance of its signal source. It is performed to achieve maximum power transfer and reduce the signal reflections from the load. In other words, for proper impedance control,...
