Optimizing PCB DFM Guidelines

Typical DFM checklists assume the use of legacy DFM formats. In a world where much of our data transfer is becoming intelligent and seamless, why are we relying on designs from 60 years ago?

Making Parts Part of Manufacturing Driven Design

When it comes to PCB assembly level MDD, many designers have not concerned themselves with the component manufacturing Bill of Material (BOM). Designers work from a CAD library that has component libraries associated with internal part numbers (IPN) their company uses. The CAD Design Rule Checking software uses those CAD library shapes for its analysis and even, in some cases, the avoidance of where components are placed. There is nothing wrong conceptually with this mentality. However, like all things, the details matter.

What materials are used in PCBS?

As a fundamental component of electronic products, printed circuit boards (PCBs) appear in every electronic product. PCBs connect all kinds of components together, making the electronic products work in the way we expect them to. So what materials are used in PCBs? Let’s look at the PCB together.
