What is an Anti-Pad? Anti-pad refers to the area around a plated through-hole, which voids or restricts other signal traces that should not be connected to that particular through-hole. This can also be added to avoid short-circuit between neighboring holes. How do we add an anti-pad in Eagle? The only way to form a layout…

What are QFN Packages?
QFN (quad flat no-lead) package is an IC component best used for programmable modules and microcomputers. It is also recommended to use this package for PCB designs with size, thickness and weight considerations. It is also known as quad micro leadframe package. Using QFN Packages Pros: Size and weight– It is a thin, compact package…

Automated vs. Manually-Created CAD Models
Are software-generated CAD models better or worse than those created manually by engineers? What are the pros and cons of each development style? In this post, we list the pros and cons of each type of model, and then share SnapEDA’s development process. Manually-Created CAD Models Manually created models are made individually based on a…

Understanding Through Hole Land Patterns
What is a punched hole? Should I use the drilled hole diameter or the finished hole diameter? I bet you’re thinking of those questions when trying to create your PCB land pattern for a through-hole component. At SnapEDA, our engineers analyzed different through-hole land patterns to help you produce the best libraries for your designs.…
