Join our insightful webinar on Altium 365 Version Control System (VCS) designed for solo users, where Ari Mahpour will guide you through creating and managing projects on the cloud-based platform.
Electronics designers working in small design houses or in large enterprises often encounter a common set of challenges when interfacing with mechanical designers. Continue reading to learn how you can best interface with your mechanical designer to get your projects out the door fast!
HDI PCBs take a particular approach to routing interconnects through multiple layers to ensure reliability during fabrication, assembly, and operation. The critical structure that enables this is microvias, which are prone to failure if not designed properly. In this e-book, readers will receive an initial look at the reasons microvia reliability has come into the spotlight and why HDI PCB designers put reliability first when routing through microvias.
Aside from impedance and annular ring calculations, one of the other major formulas specified in the IPC 2221 standard relates temperature rise, trace width, and trace current. THere is also the IPC-2152 standard, both include this guidance on designing for thermal reliability, but which standard should we use?
Striplines provide some advantages over microstrips as they take advantage of natural shielding and coupling from nearby ground plane layers. Although they tend to experience higher losses due to total confinement in the dielectric, they can be thinner due to the high dielectric constant used in internal layers of a PCB. Use our free impedence calculator to help you determine the correct width needed to hit a target impedance.
An optoisolator is a cool electronic device that can be used to pass information between a diode without passing an electrical current. There are many great applications for these, but do you know which one is right for you?
The Properties panel provides access to the properties of documents and objects. The contents of the panel change depending on the active document or the selected object. This blog will quickly go over some of need to know options around the properties panel in the schematic document.
If you’re waiting for truly connected cars on a grand scale, there is still a massive amount of work to be done, both on the hardware and software sides. Connected cars can only become a widespread reality once the automotive industry and telecom carriers can decide which protocol will work best for vehicle-to-everything (V2X) communication. PCB designers will then need to step in to create these systems and fit them into a vehicular environment.
This one area of PCB design can be contentious among some designers as it is related to copper pour, which it is often stated is not needed in most designs. Regardless of your feelings about copper pour, stitching vias have important uses in PCBs at low frequencies and at high frequencies.
The IPC-2221 standard includes many requirements for printed circuit board design and manufacturability, and there are several online calculators that have been developed based on this standard.
When you’re ready to manufacture a new device at production volume, there are many aspects of the product that must come together. The enclosure, cabling and connectors, embedded software/firmware, and of course the PCBA all have to be considered in totality. There is a quick way to get your product into a usable enclosure, complete with input power and cabling, and with a form factor that fits your PCBA. This overused route to a new product is a box build assembly.
Printed circuit board fabricators have become skilled at manufacturing these technologies and also at understanding the reliability and producibility challenges associated with high-density-interconnect technology. Let’s look at where the PCB industry is at today.
What can the industry do to support PCB designers as they continue taking a more active role in product development? Here at Altium, there has been a progressive shift towards looking at the system level and creating tools that get designers more involved throughout the product development process. As the saying goes, over the wall engineering is over… today’s most successful products are built in a collaborative process.
As the 5G rollout progresses and researchers continue to discuss 6G, many new 5G-capable products operating in sub-GHz and mmWave bands are reaching the marketplace. Devices that will include a 5G-compatible front-end, whether small stations/repeaters or handheld devices, use phased arrays as high-gain antenna systems to provide high data throughput without losing range at higher frequencies.
Via protection is an important part of modern PCB design. It provides additional benefits in PCB manufacturing and assembly, increasing the number of acceptable products.
Power integrity problems can abound in modern PCBs, especially high-speed boards that run with fast edge rates. These systems require precise design of the PDN impedance to ensure stable power is always delivered throughout the system.
A design project doesn’t appear out of nowhere. The design process spreads over time, and project documents change. Schematic documents gradually become more complex, new functional blocks appear, and already finished parts can be modified and updated.
Capacitance is your friend whenever you need stable power integrity, which is why there is so much focus on decoupling capacitors. While these components are important and they can be used to provide targeted power integrity solutions to certain components, there is one specialty material used to supercharge capacitance in your PCB stackup or package substrate.
The problems you can experience with components and libraries are endless. These problems are the most significant source of design issues and the biggest reason behind respins, costing companies untold amounts of lost profit annually.
If you want to have a better understanding of how to use Altium 365 to maintain a strong and centralized library that is free of problems and headaches, you may want to consider attending this lecture.
As much as we would like to build every high speed PCB perfectly, with ideal SI/PI/EMI characteristics, it isn’t always possible due to many practical constraints. Sometimes a stackup can be “good enough,” even for a high-speed PCB. This always comes from the need to balance engineering constraints, functional requirements, and the need to ensure signal and power integrity in a high-speed design, and finally to ensure compliance with EMC requirements.
Involving the whole team that will bring a product to completion early on in the development cycle is vital to efficient development. Design reviews with all the relevant parties are critical at each step of the design process, starting with high-level component selection, then through the schematic capture and PCB layout stages.
Ergonomics and convenience are important issues when designing a printed circuit board and the device as a whole. A lot of Altium Designer tools are aimed at solving them. These include Countersink and Counterbore holes, which allow the use of various types of screws in the mounting holes of the board.
The development of electronic devices always involves the release of many different types of files. And these files are not static - they change as the project progresses. When filling a project with data, a user creates new files, modifies outdated files that have become irrelevant. Managing project data is a separate task, especially for large developments where several participants with different specializations are involved in the process.
