Annular rings are one of the biggest concerns of PCB designers. You know that you may place your via right in the middle of the pad in the design files, but it just does not mean that you will 100 percent avoid tangencies, or even worse, breakouts. Let’s talk about...
Getting a quickturn PCB prototype is not science fiction. There are a few facts on PCB manufacturing that you simply need to acknowledge before you begin working on your design. Mistakes to Avoid for Quickturn PCB Prototype With standard technology—single lamination,...
Did you know that more than 25% of PCB failures occur due to ionic contamination? These contaminated PCBs are sent back to the manufacturer for revision. Additionally, ionic contamination may cause a catastrophic failure, leading to a substantial financial loss for a...
Drilling is the most expensive and time-consuming process in PCB manufacturing. The PCB drilling process must be carefully implemented since even a small error can lead to a great loss. The drilling process is considered the most critical and bottleneck of printed...
Vias are miniature conductive pathways drilled into the PCB to establish electrical connectivity between the different layers. Basically, a via is a vertical trace in a PCB. In this article we will cover: What is a via? Aspect ratio for vias in PCBs Aspect ratio chart...
In this video, Keysight ADS SI application scientist Tim Wang Lee shows you how to use basic signal integrity (SI) analyses such as eye diagrams, S-parameters, TDR and single pulse response to solve signal integrity problems. After learning the 3-step approach to...
Hello again, I’m Amit, the PCB guy. Today I’d like to discuss key points you should know before you get a controlled impedance PCB. Controlled Impedance PCB Must-Knows 1. How To Specify Controlled Impedance You can get controlled impedance in two ways: first is to...
HDI PCB manufacturing pushes boundaries with its fine lines and spaces. Add blind, buried and micro vias to the design and things can quickly go wrong. Here are some tips you will need to succeed in HDI. Hi PCB designers, today we are going to talk about HDI. In the...
