Here’s a tutorial on how to automatically generate Eagle parts from manufacturers’ BSDL files. These files are available from some manufacturers and include tables listing pin names and numbers. [via]

Many users often request if there are any tools that can simplify library part creation. Make-symbol-device-package-bsdl.ulp is one of those tools, it can parse a BSDL file and automatically create a part for you, device, symbol, package everything in just a few clicks. It’s one of the more sophisticated ULPs that ship with EAGLE and can be used to speed up part creation especially with high-pin count components such as FPGA and large microcontrollers. Most manufacturers such as TI and Microchip provide BSDL files for their parts. This is also one of two ULPs that come with a manual you can find it in the doc folder of your EAGLE installation.

Before tRestrict

normal ground fill using polugon on Eagle PCB

Our dear friend Vassilis notes an easy way to trim ground fills on EAGLE PCBs. This tip is really helpful if you would like to prevent ground to be filled on small areas without having to add a new polygon.

Normally, if we like to add a ground plane on a PCB we use a polygon named GND and then empty space is filled with copper attached to GND net (keepout distance from traces, pads etc can be adjusted). In most cases you will notice that copper is filled in areas that we would not like to be filled. A solution to this is to add a polygon on tRestrict layer to prevent copper to be added on that area. This solution works nice for relative large areas of board.

Another way to prevent ground to fill a small area is to use a wire on tRestrict layer placed in such a way to “cut” the ground filling path. Using such wires on the above PCB give us better results as you can see on the screen below.

bobstarr.net has revised the default Eagle libraries to suit his electronics design work and facilitate the work flow. These library files are designed to completely replace the default Eagle library set and are updated frequently.

This is a great App that allows you to view .brd and .sch Files from CADSOFT Eagle V6.x and up on your android device. The demo version allows you to view only the demo files and a paid version costs only 0.99 EUR. App works really smooth and it allows you to select your desired layers! A must have app for electronic engineers!

A great online PCB verification service for free…

For added peace of mind now you can verify your PCB data prior to placing your order. PCB Visualizer is an automatic tool for data input and manufacturability analysis. Clear graphic presentation pinpoints any issues found. You can then fix them up front, helping to avoid delays to your time-critical deliveries. Upload your Extended Gerber (RS274X) or CadSoft EAGLE V6 files and let us surprise you.

Tutorial: Creating Accurate Footprints in Eagle @ The Adafruit Learning System

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.

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.

Multilayer PCB

dangerousprototypes.com writes:

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]
