Are you still verifying your PCB prototype visually?

After completing component placement, it may take months for designer to complete the routing process and finish the entire PCB layout. At this point the CAM data can then be handed out to manufacturers for PCB manufacturing and assembly. After investing this much time and effort, you would probably expect the final prototype to be built as expected, with high quality and reliability.

Are your alternative parts well validated before release

In alternate part selection, many aspects need to be considered: electrical function, physically fit, supply chain flexibility, cost, etc. Every aspect is important during alternative part selection, but realistically, electrical and physical fit are the main prerequisites when choosing a new alternative part.

What’s New in Valor NPI 2311

Each new Valor NPI release brings exciting features and improvements, and Valor NPI version 2311 is no different. One of the most prominent recent changes for release 2311 is the 3D board viewer. This allows users to toggle between the typical 2-D board view, and a 3-D board view. While less visually prominent, the addition of high-risk component detection is no less impactful among the overall improvements. The Valor Parts Library now associates individual components with a manufacturing risk value. This allows you to consider at-a-glance relative yield values based on component choices. Valor NPI version 2311 also facilitates the placement of XD components in a zigzag array.

Solder strength testing and validation

Strengthening PCB Solder Connections

To increasing the overall solder strength within a PCB design, designers should be focusing on two distinct but related factors: The material composition of the solder, and the pad and footprint layouts for individual components. The composition of the solder itself will depend upon the application of the board, the components, construction method and materials within the board, and the overall final board quality. The overall footprint of the component will be dependent upon the components within a BOM and the recommended assembly guidelines of your assemblers. Both of these factors rely on discussions and interactions with your assembly house and leaving these discussions until after the design has been released ultimately limits your assembly options.

PCB Design and Stencil

Stencil design considerations during library cell design

Library cell design seems to be an easy part of the entire design process, but in reality, it can be a complicated part of this process, as it involves many different aspects to consider. It should not only comply with the electrical needs, but also needs to meet manufacturing requirements. Solder paste printing is one of the manufacturing processes that may need considerations during your library cell creation. To be more straightforward, the stencil design is something need to be considered during library cell design.

How to Optimize PCB Design for the SMT Assembly Process Flow

PCB (Printed Circuit Board) design layout optimization is critical for the success of SMT (Surface Mount Technology) assembly. SMT assembly involves placing surface mount components directly onto the surface of the PCB, as opposed to through-hole components, which require holes to be drilled through the PCB. SMT assembly is faster, more precise, and more cost-effective than through-hole assembly, but it requires careful design optimization to ensure a successful assembly process.

Migrating from Gerber to ODB++ CAM Compare

Gerber files have long been the industry standard for PCB design and manufacturing data. However, with the increasing complexity of modern designs, Gerber files have become less effective in conveying all the necessary data required for manufacturing. ODB++ is a newer format that was developed specifically to address the shortcomings of Gerber files. ODB++ is a comprehensive format that includes all the necessary data for manufacturing, including component placement, drill files, and manufacturing details such as the thickness of the PCB and the type of solder mask just to mention a few.

Manufacturing Driven Design – Taking DFM to the Next Level

Manufacturing Driven Design (MDD) is an evolutionary approach to DFM. It enables the effortless exchange of manufacturing process constraints so that an OEM can assess the manufacturability of a design in perfect alignment with their supplier
