One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).
Being able to design a board in your ECAD environment doesn’t mean that it is manufacturable in real life. You have to make sure your CAD representation won’t have any problems in the real world by taking some precautions. For example, there are certain areas that need to be free of components and have specified clearances like your board edge. This webinar will help you get acquainted with the creation and modification of your board shape so that you can ensure manufacturability.
There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.
During this year's AltiumLive CONNECT event, I recall receiving an interesting question about the skin effect and the distribution of current due to the presence of ground in coplanar transmission lines. In this article, we'll look at the electric field around a transmission line carrying a signal, and how this might be impacted by the skin effect.
When you get your PCBA back from an assembler, you’ll notice the packaging materials used to pack and ship the PCBA. Those materials are specific to electronics, and if you build products on behalf of clients, it’s important to know the packaging materials used for packing and shipping electronics. In this article I’ll show the main set of materials and equipment used to package electronics assemblies.
Once you've got your PCB layout finished and you're ready to start preparing for manufacturing, one of the critical steps is to create PCB Gerber files. When you're ready to create your Gerber files, you need the right set of CAM processor tools that can take data from your PCB layout. In this article, we'll guide you through this process of how to make PCB Gerber files and show some example tasks you might need to perform to generate them.
There are many aspects to designing a PCB. One of the larger aspects has to do with managing your components. We all need components for our designs, but are those components in our library and designs up-to-date or even purchasable? These questions need to be answered before we can safely use them. Altium Designer® has several tools to help you manage the components in your libraries and designs.
One of the major factors impacting reliability of a PCBA is the use of teardrops on traces in the PCB. Like many aspects of reliability, the considerations also span into the signal integrity domain, particularly as more high-reliability products require greater data handling capabilities and run at higher speeds. In this article, I’ll break down the issues present in teardrop usage on differential pairs and how these may affect impedance.
High-reliability electronics must go through multiple rounds of testing and qualification to ensure they can withstand their intended operating environment. Designing to performance standards, whether the baseline IPC standards or more stringent industry standards, is the first step in ensuring a reliable circuit board. In this e-book, readers will gain a thorough look into PCB testing and analysis, starting from basic tests performed on bare boards and completed assemblies.
Coupling capacitors find plenty of uses in analog applications and on differential protocols, acting essentially as high pass filters that remove DC bias carried seen on a signal. In the case of PCIe, there are a few reasons to place AC coupling capacitors on differential pairs beyond the fact that AC coupling capacitors are listed in the standard. In this article, we’ll look briefly at where to place coupling capacitors on PCIe links, as well as the reasons these are placed on PCIe links.
