PCB DFM Constraints with Valor NPI

Advanced DFM Constraints management in ADM (Analysis Definition Manager)- Valor NPI 2211

The Analysis Definition Manager (ADM), introduced in Valor NPI 10.0, is a constraints management tool for creating and maintaining sets of Design for Manufacturing DFM rules to be used during the analysis in Valor NPI.

What's new with Valor NPI DFM software release 11.5

What’s new in Valor NPI v11.5

Valor NPI 11.5 continues to introduce new and existing capabilities in MRA-Revolution, with a more complete Classification set which includes design preparations and analysis use of copper reference layers. Comparing an ODB++ to fabricator changes becomes easy and precise with the new CAM Compare flow and the first connection to stackup setup is established with Z-Planner integration.

What is New Product Introduction (NPI) and How Does it Apply to PCBs?

The pace of PCB new product introductions has increased exponentially over the past few years – and with it the need for a proper NPI process. It’s not just that PCBs are used in more and more products across numerous industries; it’s also that more PCBs are needed in those products. For example, consider how many PCBs are used in even the lowest-end cars today versus how many were used years ago. As new-model cars become increasingly connected to online services, the need for PCBs will continue to grow.

PCB stackup with material and copper

PCB Stackup Design e-book

While not the final word on the subject of stackups, Bill’s e-book goes a long way to helping you plan ahead, providing an important voice in a space that is surprisingly lacking in content. I would also recommend exploring Z-planner Enterprise, a stackup tool that Bill has spent years developing. Now all you need is a sharp pencil.

What is Design for Manufacturing?

PCB DFM looks at all factors that may impact the manufacturability of a PCB design, such as assembly, fabrication, flex/rigid-flex, microvia, panel and substrate. It should also consider whether SMT component placement and soldering can be conducted automatically to reduce costs. DFM can involve general manufacturing specifications and/or the specifications of a specific manufacturer.
