One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. We will wrap up this DFM series with a summary of cost drivers that impact delivery, quality and reliability. It is categorized by low-, medium-, and high-cost adders.
Slash sheets can be confusing, and this is a big topic, so let’s start big and drill down from there. Here’s the big picture regarding slash sheet references: They were designed to provide handy groupings of PCB materials (laminates, polyimides, etc.) that go into a stackup. These groupings are designed around mechanical characteristics to provide insight for PCB fabricators to identify similar laminates with similar properties.
When looking at the PCB industry, an outsider may have the illusion that the typically green-colored substrates populated with components use only a small amount of technology. The term printed, along with the notion that you can...
Signal integrity (SI) grew out of the electromagnetic compatibility discipline in the early 1990s and gradually became a hot topic in its own right. Although the term SI never appeared in the title, one of the first books on topic was...
Let's learn about annular rings, because a greater understanding can help ensure that your PCB designs successfully become physical boards. The annular ring is the space between the drill hole and the edge of the pad—a specified...
