this article can be taken as both ways, as a revenge 😮 or a guideline for what not to do. The decision is purely up-to reader. Technie X has decided, clues from personality should be used to model into design decisions.
The effectiveness of the decoupling at high frequency is dependent on the number of capacitors used as opposed to the low frequency where it depends on the value of the capacitor used.
The best PCB layout starts on the foundation of component placement. It is wise to not rush the process. Every extra iteration should add up niche a feature or remove a short-coming. Picking up a small detail and reducing the effort of routing by this creative process is the most challenging phase in PCB design life-cycle. But it’s totally worth it.
Good PCB stack-up is very effective in reducing differential and common mode emission from the board. Choosing a PCB stack-up in the design process is analogs to the foundation for a house. Hence selecting it carefully can save a lot of costs afterward occurring towards mitigation of EMI/EMC issue.
The PCB layout doesn’t have a fixed set of rules, hence every designer generally employ a set of guidelines while using their engineering judgement. These Guidelines set out best practice to reduce the cost of boards and to minimize the risk of errors arising during manufacture.
A good list of checks to make before committing the design of a new printed circuit board is an essential ingredient for quality assurance.
While some portions of the circuit performance are dictated by the schematic and BOM, the PCB layout finally decide the fate of design. During layout, we often need to use engineering judgment on the trade-off between the size, cost, testability, and manufacturability of the board.
Board bring – up is a planned process whereby an electronics system, including assembly, hardware, firmware, and software elements, is successively tested, validated, and iteratively debugged in order to attain manufacturing readiness
We have categorized the checklist in multiple sections for a systematic checking. There are many details that go into making a successful first – run design, and this checklist helps prevent bugs from marrying a healthy design otherwise.
This article is going to cover the review part of the schematic design in a hardware flow which ensures minimum error and hence maximum reliability.
