While sometimes quick and dirty works fine for footprints, if you ever have to deal with enclosures or particularly dense boards, you’ll soon find out that accurate footprints can make your life much easier.
There are some really nice, detailed and accurate footprints in the default Eagle libraries, but there aren’t a lot of resources out there on how to create them. This guide will hopefully serve that purpose, highlighting what works for me making connectors and similar types of footprints.

Florin made a head to head comparison of Seeed and ITead’s inexpensive PCB services. He made the orders with the same design files, on the same day. While the Seeed order came in after 4 weeks, ITead’s came just 15 days after the order was made. The author however suspects it might have been a fluke, since all his earlier orders from ITead took around 4 weeks to complete too.

In Eagle polygons are used to make big copper areas on a PCB that aren’t necessarily traces. We use them all the time to fill blank space on a PCB with copper connected to ground. Less frequently we use them to make large power traces such as with the ATX Breakout Board. Here’s some notes on how to use and customize polygons in Cadsoft Eagle.

There are many CAD developed to assist the electronic designers during drawing of PCBs and schematics; often they are integrated in complete suite to project, simulate and realize a whole electronic system. Besides the many commercial versions, there are also free CADs available. Today we’d like to analyze one of the most diffused and known software: Eaglecad (eagle does not mean the powerful bird but it is the acronym of Easily Applicable Graphical Layout Editor) made by Cadsoft, actually at version 6.2.0. We have chosen this one because, as you know as an Arduino’s fan, the official pcbs and schematic files of the boards are developed and available free of charge to everybody in Eaglecad format; you can find also a lot of libraries and circuits made by famous DIY website (Sparkfun for first) available for free.

Rik shows how to design PCBs with more than two layers in Cadsoft Eagle. The tutorial covers the basics, as well as some advanced subjects like BGA escape routing. Keep in mind you’ll need a standard or pro version of Eagle, as the free version doesn’t support designs with more then 2 layers. [via]

ZofzPCB is a gerber viewer geared to make verification quick and easy. It shows the board and layers in 3D so it’s easier to spot errors. It can also make each trace a different color so the location is clearer. [via]
- ZofzPCB 3D Gerber Viewer can display 3D PCB model, using your design CAM files.
- Gerber and Excellon files are assigned to layers in auto or manual mode. – Stackup dimensions are fully editable.
3D approach allows more direct visual examination of your design.
- ZofzPCB 3D Gerber Viewer aided by DirectX and modern graphic hardware, brings impressive real-time images to your desk.
- ZofzPCB recreates netlist and can mark each net with different color.
- ZofzPCB allows you to take mechanical measurements, also between layers.

As consumer devices continue to shrink in size, power considerations and appropriate thermal design become increasingly important for circuit designers and board layout engineers. This tutorial helps designers to ensure that a board is both electrically sound and thermally balanced for proper operation and optimum efficiency.

Most chips have multiple power pins that need to be connected to the same power supply, but Eagle doesn’t allow you to give 2 different pins the same name. This short tutorial shows how to get around this and name multiple part pins the same thing.
