WEBINAR RESCHEDULED: iNEMI PCB Connector Footprint Tolerance End-of-Project Webinar — Join us Thursday, October 28, for information about this project’s investigation of industry capability, risks and mitigation strategies associated with high-bandwidth I/O connector footprints. The ongoing reduction in connector pitch imposes stringent design requirements on PCB fabrication processes. This iNEMI project aimed to provide product designers with the information necessary to ensure predictable quality levels when using high-bandwidth connectors. The team identified potential risks and surveyed the PCB industry to assess supplier capabilities for appropriate quality mitigation. Join us for this end-of-project webinar where we will review the survey results and highlight areas of expectations and gaps between PCB fabricators and connector manufacturers. Additionally, the team will present recommendations for quality assessment and dimension control. Get additional details. https://lnkd.in/eHYXdhKx   

Are you risking PCB design failure by choosing the wrong components? Here are the key considerations to keep in mind: 📌 Define Your Requirements: Clearly outline the functionality, environmental conditions, and regulatory standards for your design. 📌Component Compatibility: Verify compatibility with your PCB material, operating temperature, and signal integrity requirements. 📌Form Factor and Packaging: Choose components that fit your design's spatial constraints and assembly process. 📌 Supplier Evaluation: Research and select reputable suppliers with reliable quality, lead times, and pricing. 📌 Cost vs. Performance: Balance component costs with performance requirements to optimize your design. #PCBDESIGN #MASTERTHEARTOFPCBDESIGN

Here are five key mistakes and how to avoid them: 1. 𝑰𝒎𝒑𝒓𝒐𝒑𝒆𝒓 𝑻𝒓𝒂𝒄𝒆 𝑫𝒆𝒔𝒊𝒈𝒏🖋️ PCB traces must be sized correctly based on current flow to avoid overheating and signal issues. Use appropriate tools to determine the right width and thickness. 2. 𝑷𝒐𝒐𝒓 𝑪𝒐𝒎𝒑𝒐𝒏𝒆𝒏𝒕 𝑳𝒂𝒚𝒐𝒖𝒕🧩 Compact designs can cause spacing issues, leading to connection problems. Ensure enough space between components and plan for future expansions. 3. 𝑰𝒏𝒄𝒐𝒓𝒓𝒆𝒄𝒕 𝑫𝒆𝒄𝒐𝒖𝒑𝒍𝒊𝒏𝒈 𝑪𝒂𝒑𝒂𝒄𝒊𝒕𝒐𝒓 𝑷𝒍𝒂𝒄𝒆𝒎𝒆𝒏𝒕🔋 Decoupling capacitors must be close to the components they serve. Proper placement prevents voltage instability and circuit oscillations. 4. 𝑬𝒙𝒄𝒆𝒔𝒔𝒊𝒗𝒆 𝑽𝒊𝒂 𝑼𝒔𝒆🛠️ Blind and buried vias increase costs. Plan their use carefully to avoid unnecessary expenses while maintaining efficient connections. 5. 𝑵𝒆𝒈𝒍𝒆𝒄𝒕𝒊𝒏𝒈 𝑫𝒆𝒔𝒊𝒈𝒏 𝑹𝒆𝒗𝒊𝒆𝒘𝒔👀 Regular design reviews are vital for catching errors early. Peer reviews can uncover overlooked mistakes, ensuring a reliable final design. By avoiding these common mistakes, you can create more efficient and reliable PCB designs....!

What are the differences between #IPC class 2 and class 3 in #PCBmanufacturing? Here are a few rules: - For class 2, 90 degrees breakout of the hole from the land is allowed, provided minimum lateral spacing is maintained. Class 3 does not accept any lifted or fractured annular rings. - For class 2, the conductor junction cannot be reduced by more than 20%  of the minimum conductor width specified on the engineering drawing. The conductor junction should never be less than 2 mil or the minimum line width, whichever is smaller. - For class 3, the minimum internal annular ring cannot be less than 1 mil. The external annular ring cannot be less than 2 mil. It is measured from the inside of the PTH barrel to the edge of the land pad and may have a 20% reduction of the minimum annular ring in isolated areas due to defects, like pits, nicks, pinholes, or dents.

info about PCB Panel: What is PCB Panel? The panel refers to the platform where the circuit board is fixed for full production. In another perspective, it has to do with panelization – the process of fixing several circuit boards on the same panel. How Important is PCB Panelization? The panelization of a circuit board is important for these reasons: 1. It helps the circuit board designer to determine the number of panels that are required for the board. 2. With panelization, multiple circuit boards can be fixed to form a single array. 3. You can also use panelization to determine the amount of waste to be realized per panel. 4. PCB panelization could aid in streamlining the production process, especially with the formation of a larger panel and the placement of individual, smaller circuit boards on the top. Common PCB Panel Sizes You will find an array of options when measuring the size of a circuit board panel. The common measurements include: 18 by 24 inches 18 by 12 inches 9 by 12 inches 9 by 24 inches There is also a need to have a space between the boards on the panel. This is essential for automated routing and allowing for manual removal. The space given often differs by the PCB manufacturer – while some go with the standard 0.5-inch or ½, others would prefer 1-inch.

Did you know that there is a way to see exactly how well your PCB is soldering in real time so you can avoid poor or dry joints? Momentum Circuits offer a service to include a retainable 'coupon' in the waste material of your PCB that includes not only all the important information you need (part number, date code, UL flammability rating, factory ident etc), but also the strips of the solderable finish that give you an immediate solderability indicator for every panel. Our PCB engineers include a pattern of small dots of solder paste in the step & repeat data you use to manufacture the solder stencil and they go from virtually touching each other at one end of the strip to slighting increasing gaps down the length. Once the solder reaches temperature and turns to a liquid, the dots will join together (coalesce) up to a point and give you an instant linear indicator of how well the solderable finish is wetting. If the panel is old or the solderability isn't great (i.e. when the dots don't join very far), you can adjust your profile accordingly and avoid attrition. The better quality the solderable finish, the further down the strip the dots will join together. It is a useful free feature that adds value to waste material that would normally just be thrown in the bin. Clever solutions from an innovative PCB supplier.
