Everything You Need to Know About Ferrite Beads Everything You Need to Know About Ferrite Beads As noted in my previous blog regarding PDS design, the whole power supply conundrum is one that has been plagued over the years with a number of erroneous rules-of-thumb; “black magic” design rules and confusion as to what does or doesn’t work. One of the most controversial topic areas focuses on the use of ferrite beads as a means of controlling and containing EMI. There is conflicting information concerning the use of ferrite beads and it is 記事を読む
The Art of Selecting Connectors The Art of Selecting Connectors Connectors are the unsung stars of both a product and its hardware development. Any Apple user knows the romantic tale the company has spun from infatuation with the first magnetic power connector through the betrayal of the 3.5mm jack to today’s ‘it’s complicated’ status thanks to the baggage their dongles create in pursuit of beauty. Product developers have similar emotional experiences with their prototypes. An unreliable connector that has 記事を読む
How To Design the Perfect PCB Stack Up With Altium Designer How To Design the Perfect PCB Stack Up With Altium Designer In the last 20+ years, electronics have become increasingly more complex. Board density is always being pushed to the limits, EMC/EMI regulations evolved and got stricter, and edge rates have become smaller. Therefore, the PCB Layout engineer needs a good understanding of EMC, PDN, EMI, and SI in order to route a modern PCB with confidence. In this article we’ll talk about some of the considerations we should have in order to create a PCB stackup 記事を読む
Multi-Board Design Basics Webinar - August 2018 The webinar touches on electrical and mechanical challenges of system and product level multi-board PCB design. A demonstration follows, showing how to mitigate the challenges of the PCB design process with the capabilities of Altium Designer. You need to manage the whole system connections, resolve conflicts, and update system-child projects. Coordinating separate board rotation, alignment, and enclosure fit is like a game of three-dimensional PDFをダウンロード
Creating a Ground Plane for Your PCB Design Creating a Ground Plane for Your PCB Design It used to be that printed circuit boards seemed to have the same basic layer configuration, or at least that’s the way I tend to remember it. This meant that they were usually six layer multi-layer boards, with a ground plane and a VCC plane. The old CAD systems didn’t really have the ability to do much with power planes except to designate layers as a bottom layer or the like. The most you would see in them would be some “X’s” where there was 記事を読む
mmからmilへの単位の切り替えとその他のPCB設計に関連する測定プリファレンス mmからmilへの単位の切り替えとその他のPCB設計に関連する測定プリファレンス かつては、PCB設計者が使用する計測単位は、設計者がその時点で住んでいる場所によって異なっていました。標準的な計測単位は、次第にメートル単位になり始めましたが、問題は、多数の古いデータシートや設計にインチ単位が使用されていたことです。設計者は、常に2つの単位を変換するため、メモ帳、電卓、アスピリンをそばに備えなければなりませんでした。 設計者にとって画期的なサポートとなったのは、CADプログラムに、ソフトウェア内で計測単位を切り替える機能が組み込まれ始めたことです。これによって、手作業で変換する必要がなくなりました。Altium Designerは、ユーザがmmからmilに簡単に切り替えられるPCB設計システムの好例といえます。PCBを設計する場面では、このような柔軟性が、その他の多数のシステム設定やプリファレンスとともに、多くの時間を節約し、頭痛のタネを解消してくれます。時間の節約につながるこれらの機能について、簡単にご説明します。 回路図でのmmからmilへの切り替え 記事を読む
Altium Designer: PCB設計でプロジェクトテンプレートを使用するメリット Altium Designer: PCB設計でプロジェクトテンプレートを使用するメリット 馬の家畜化、車輪の発明、燃焼機関の開発は、人間がより効率的にあちらこちらに移動したり新しい場所を探検したりできるようなるという点で称賛できる、非常に画期的なできごとです。慣れた環境から見知らぬ場所に出ていくための自信を多くの人に与えるという点で、少なくとも同じくらいの称賛に値するもう1つの発明があります。それは地図です。自分より前に誰かが道を通ったということがわかっていると、目的地にたどり着く自信が持てます。 PCB設計は、試行錯誤で埋め尽くされる可能性のある創造的なプロセスです。このプロセスからエラーを取り除くことは実質的に不可能ですが、プロジェクトテンプレートを使用することで最小限に抑えることはできます。最も基本的なところでは、プロジェクトテンプレートは実際上、以前に設計された回路の「地図」です。自信を持って、これを新しい設計のベースとして使用することができます。Altium Designer 18ではこの基本概念が拡張されていますが 記事を読む
pcb cost estimate Designing to Meet a Target BOM Price and PCB Cost Estimate Creating an accurate PCB cost estimate for design, components, production, assembly, shipping, and even firmware can be challenging tasks for new designers. Even established organizations can have trouble getting it right as it's hard to anticipate every problem that can arise during a design. Manufacturers can help you handle the production and assembly portion of a project, but any time a new design needs to be put into production, components 記事を読む

Manufacturing Checklists and Tools When it comes to manufacturing, organization is critical. With so many different players involved in the design process (engineers, sourcing agents, manufacturers, etc.), maintaining documentation and utilizing checklists and other tools will keep everyone on the same page and avoid confusion. Additionally, checklists can help ensure that the PCB design is fully complete and ready to send for manufacturing, protecting you from any unexpected PDFをダウンロード
Generate Gerber Files in Altium Designer Step-by-Step from Schematic to PCB How to Generate Gerber Files in Altium Designer Step-by-Step Once you've got your PCB layout finished and you're ready to start preparing for manufacturing, one of the critical steps is to generate Gerber files. These files are used by PCB manufacturers to prepare stencils for photoresist exposure and subsequent etching. When you're ready to create your Gerber files, you need the right set of CAM tools that can take data from your PCB layout. Altium Designer helps make the process for generating Gerber 記事を読む
Preventing Ground Loops in Your PCB Design Preventing Ground Loops in Your PCB Design I think we’ve all been there. You buy that awesome stereo system only to hear that familiar humming sound in the background. When you take it back to the store the clerk blames the manufacturer. What components are to be considered a problem? The decoupling capacitor or ground wire? How about the bypass capacitor or ground loop interference? The stereo manufacturer will blame the component manufacturer and the component manufacturer can’t blame 記事を読む
Understanding Ground Planes in Your Two-Layer PCB Understanding Ground Planes in Your Two-Layer PCB Back when I was a young and hungry grad student, my first PCB ground plane design was used to collect analog signals from several sensors. When looking at a voltage graph of my measurements, the noise level was horrible and completely masked the signal I was trying to measure. I soon realized that I had completely bungled my ground plane connections, and ground loops were ruining my signals. Placing your ground plane and routing to ground are two 記事を読む

Simplify Schematic and PCB Designs by Highlighting Nets Better PCB Routing - Highlight Nets Regardless how many PCBs I design, I always find myself having to regularly review network paths on schematics layer and trace routes on PCBs. The complexity reminds me of a maze where only one path is the right one for a particular network. It is imperative that all the connections are accurate as errors made here will come back to haunt you later in the form of redesigns. The best way to ensure network accuracy is by isolating it so that each 記事を読む
BOM Planning for Different Levels of Production BOM Planning for Different Levels of Production There is one really great thing about social media and that is catching up with old friends. I connected with a high school friend who did a lot in his life including some great achievements in the world of Taekwondo. He talks about the different tournaments that he attends, the people that he associates with, and how he has progressed through the different levels of this discipline. There appears to be a lot more to Taekwondo than I would have 記事を読む
