EAGLE ULPs Every User Should Know

CS_EAGLE_Logo_400px

by Dave Young @ element14.com:

A ULP (User Language Program) is a feature designed into EAGLE to allow users to generate their own processes to automate tasks that would otherwise be tedious and time consuming. While most users know that this functionality exists, very few want to write their own script. A casual user would have to dump far more time learning the system and designing/testing their code than just completing the task at hand.

App note: PCB Design Guidelines for QFN and DQFN Packages

MC_AN18.15

Design your PCB involving QFN or DQFN packages with this App note from Microchip.

Successful implementation of QFN and DQFN packages requires special consideration for printed circuit board (PCB) layout and solderpaste stencil production. This application note describes the important items to consider.

QFN packages are physically robust, thermally efficient, and occupy much less PCB space than equivalent QFP packages. They generally have superior lead inductance characteristics. They also present some particular design constraints. QFN packages generally have a row (QFN) or two (DQFN) of perimeter pads (“pads

PCBWeb – Free Online PCB Design Software

PCBWeb00

PCBWeb01

A new PCB design web application was released this last week called PCBWeb. The website states that PCBWeb is a free browser-based CAD application for designing and manufacturing electronics hardware.  The tool is currently released in BETA and allows you to create a schematic, full circuit board layout, and then export to gerber format for manufacturing. The application is supported on Windows and Mac using Silverlight.

Features include:

Schematic Capture

  • Multi-sheet schematics
  • Custom Ports
  • Digi-Key Part Library (+100K components with symbol and footprints)
  • Cut/Copy/Past and full undo/redo

PCB Layout

  • Multi-layer board
  • Support for all units (mm/inch)
  • copper pour

Texas Instruments has announced the introduction of the PowerLab Reference Design Library, a collection of power management reference designs. The reference designs include relevant technical documentation, such as circuit schematics, printed circuit board layouts, lists of components and materials, Gerber files, and other design support tools.

The library holds more than 300 power management reference designs for a variety of both isolated and non-isolated power conversion topologies suitable for lighting, telecommunication, computing and consumer electronics applications.

An interactive search tool is available on the website and new designs will be added to the database each month. [via]

PowerEsim- Free on-line switch mode power supply SMPS, circuit and transformer design, calculation, simulation software. More than 100 circuits and topologies are available with real constructed transformer.

It provides a virtual laboratory environment for users to wind and place every single turn of a transformer, and with the help of tens of thousands real modeled component on the market, user can simple pick and place the real component and stuff into the circuit, within a fraction of a second, our server will immediately return the result to the user. It is even faster than modifying prototype in real environment, and more than that is no worry of getting explosion of the prototype on real bench. It is Better than real.

Upverter.com – Real-Time Collaboration & Shared Designs

For the first time, hardware can be collaborative in real time! Work on a design with your team, in real time! See what they are editing while you edit! Sign up for free to give it a try! Exclamation mark!

Add your team by username or email to invite them to work with you on your design. It has never been easier to add people to your design!

And while we were at it, we thought that we should give the project pages a face lift! So we called on our design surgeon to give us the great new look that you can see here.

Plus, we’ve added a ton of awesome features that you should know about!

  • Favouriting parts: We are making it easier to find parts that you know and like to use. Search will be taking this into account when you are logged in. I can’t wait to see my favourites skyrocket to top of search!
  • Tutorials: We’ve created a tutorial section to help you navigate the site and use our features.
  • Easier part creation: Introducing mouseless part creation! When editing pins on a part, just press enter to save it and go to the next pin, all the way around the part.
  • Fork with history: Design history is now copied when you fork a design. Try forking one of our featured designs. And while you’re at it, take a look at the project fork list on the project page.
  • Gravatars: We’ve hooked up your profiles to Gravatar. If you didn’t have a Gravatar, you get a little robot!
    Increased tool stability: We’ve been busy making lots of improvements to the schematic capture tool, to increase its stability and help us track down bugs in the future.
  • Netlist and export fixes: Some designs would not export netlists or to our open JSON format, but we’ve been good little beavers and this has been fixed.
  • Now with more exclamation marks!
