PCB123® launches access to millions of cloud-based symbols & footprints

Designers can now search SnapEDA’s vast component library directly in PCB123

MULINO, OR and SAN FRANCISCO, CA (September 13, 2017) — Today, Sunstone Circuits, creators of the free PCB design tool, PCB123, and SnapEDA, the Internet’s first parts library for circuit board design, are launching a new integration that allows designers to search for digital models directly inside the PCB123 design environment.

Designers have traditionally wasted days creating digital models for their designs. This process is tedious, time-consuming, and error-prone. With today’s release of PCB123 Version 5.6, designers can now search and download free, cloud-based symbols and footprints directly during design capture and layout, significantly boosting design productivity.

“For forty years, PCB designers have frittered away countless hours defining parts because there simply wasn’t a workable, affordable source for accurate, ready-made parts. In fact, surveys show that most professional designers spend an average of 30-35% of their design time just making new parts definitions before they can even get started,” said Nolan Johnson, CAD & EDA Product Marketing Manager at Sunstone Circuits.

“SnapEDA has disrupted that dynamic in an easy-to-use, no-cost utility, and PCB123 is proud to be bringing true in-tool integration of SnapEDA’s parts search functions to our loyal users – in a free PCB CAD tool, no less,” Johnson added.

PCB123 is a free, full-function PCB CAD tool, comprised of a schematic editor, physical layout editor, 3-dimensional mechanical previews, and BOM editor. By augmenting the tool with cloud-based libraries, designers will get real-time access to new symbols & footprints added to SnapEDA’s catalog, as well the ability to request parts they need for their designs with InstaPart, the company’s popular 24 hour parts request service.

“PCB123 has just released the industry’s first pre-installed integration of a cloud-based parts library. Their impressive solution will benefit PCB designers with access to vetted parts models that will shave days off design time, and benefit the world through faster innovation,” said Natasha Baker, Founder & CEO of SnapEDA.

All new models created by SnapEDA conform to the latest IPC standards (IPC-7351B) and are vetted with its patent-pending verification technology. Design content is available for millions of electronic components, enabled by SnapEDA’s proprietary, automated library creation, translation, and verification technology.

New parts library for Mentor PADS & DX Designer accelerates PCB design

Designers can build circuit boards faster with millions of symbols & footprints on SnapEDA.

July 18, 2017 –  SAN FRANCISCO –  Mentor, a Siemens business, and SnapEDA, the Internet’s first parts library for circuit board design, are announcing new support for Mentor PADS® and DX Designer on SnapEDA.

Whether building satellites or medical devices, hardware designers spend days creating digital models for each component on their circuit boards, a painful and time-consuming process that hinders product development.

With today’s launch, Mentor PADS & DX Designer customers will gain access to SnapEDA’s extensive component library containing millions of symbols, footprints, and 3D models, further enhancing the vast resources available for Mentor PCB design software.

All parts are auto-verified with SnapEDA’s proprietary verification technology, helping to reduce risk and unneeded, costly prototype iterations. This technology answers common questions designers have about libraries, such as “what standards does this footprint conform to?”

As the world becomes more connected, electronic devices are proliferating and diversifying, and time-to-market is more crucial than ever for companies to stay competitive.

PCB Droid – First Mobile PCB Designer App

The applications available nowadays serve our everyday life well. Would it be the need of our entertainment, business life or lifestyle. However, there is one special field where we could face a serious shortcoming and it is the engineering field. I’ve come across a demand through forums specialized in electronics for a mobile application, designing printed circuits on your mobile device.

The goal was to create an application, which can be used as a designer tool for printed circuits and exporting those into different formats in an Android and Windows 10 environment. The consumption of these mobile devices is a fraction of their desktop sidekicks and an app such makes designing easier, even in your daily commute. This realization gave birth to PCB Droid application. As an electronic hobbyist as far as I’m concerned others engaged in DIY electronics usually don’t utilize the possibilities and professionalism of these programs. In practice, PC printed circuits designers are using circuit diagrams as an input. Hobbyists pretend to prefer designer programs where they can draw the marginal strips themselves and adjust them on the printed circuits. PCB Droid doesn’t require any kind of previously made circuits diagrams. The parts can be drawn onto the printed circuit by the user starting from the basic elements to the most complex components.

PCB-Investigator Now Supports Browser-Based PCB Design Review

PCB-Investigator is a CAD software developed by EasyLogix for circuit board design and PCB quality assurance. Its latest version came earlier in February with a new browser interface that enables electronics assemblers to do PCB review processes without the need for local installation.

By using the ODB++ data format, PCB-Investigator creates a common database, which documents every change, and is accessible to everyone involved in the development, quality assurance and production process. With the software’s comprehensive visualization, export and import capabilities, all layout reviews are easier. Errors can be fixed earlier and prototypes can be reduced. Further improvements in version 8.0 are an improved component library with editor capability as well as clearance and creepage distance measurement.

EasyEDA’s Free and Online Gerber Viewer

EasyEDA is a cloud-based EDA tool suite which supports open source and working collaboratively.
Tools from EasyEDA include circuit simulation using Spice, PCB design, electronic circuit design and now RS-274X (Gerber) and Excellon gerber viewer, all are free.
To use this viewer you need to upload your gerber files, in RS-274X format, in a zip file.

easyeda_gerber

EasyEDA’s gerber viewer allows zooming in/out the imported gerber files, choosing the color of PCB, exporting to image, enable/disable view of layers (files) of gerber, sharing the gerber online using the URL after uploading the files and showing some analysis data (Design for Manufacturing DFM) from gerber files like the number of layers, hole and track sizes, clearances and dimension of board.

EasyEDA offers some tutorials/links to learn how to export gerber files for different EDA tools like: Kicad, Altium ,Eagle and  Diptrace.

How to Create Inverted Silkscreen in Cadsoft Eagle

If you’re one of EAGLE CAD fans, and you were wondering how some boards like Arduino boards have what’s called a negative silkscreen, hollow rectangles or shapes by text or logo, then you will learn how to do it with Ishaan’s video tutorial.

Arduino Board

Ishaan used a ULP called “negasilk.ulp” in his tutorial. It is written by Christian Bohrer, and it can be downloaded here.

We’ve tested  this trick in ElectronicsLab using these steps:

  1. Adding some texts on layer 41tRestrict.
  2. Drawing a rectangular polygon in 1Top layer with width 8 mil (according to Ishaan, this ULP accepts only this width), and don’t forget to hit ratsnest.
  3. Run negasilk.ulp.
  4. A script file is generated in the same directory of your .brd file, open it and make the following modification using any text editor (adding layer 21 line).
    Set Wire_Bend 2;
    LAYER 21;
    GRID MM;
  5. Finally, delete the unwanted polygon and text from layer 41 and layer 1.

You can see these steps in the following GIF(click to view):

Eagle CAD Tips and Tricks Part 2

ripupall

This is the second and final article of the Eagle Tips from allaboutcircuits.com:

Before searching on the internet for new libraries to add to Eagle, first make sure that your device does not already exist in your local libraries. To check, use a search pattern that includes ‘*’.

For example, if you want to add a 7805 5v regulator, you must search for *7805* instead of 7805. This will search for any part with 7805 in the middle of the name, without regard for the beginning or end of the part name.

Design & simulate in the clouds

dscloud1

by Michael Dunn @ edn.com:

It was a few years ago that I first heard of a free site where you could draw and simulate designs. “What’s the point?” I thought. But, the idea is taking off. Was I wrong?

I questioned the usefulness of this cloud concept because there had already long existed good, free circuit simulators. A quick download, and off you go, drawing and simulating. Why deal with the extra vagaries of service-provider availability, and of course, Internet access?

Well, as with any other cloud-based service, there are advantages, such as being able to work anywhere, on any supported device, and not having to deal with the software directly. And while the services out there now seem mostly suited to exploration, hobby, and simple prototype use, they will keep getting better. Some are arguably already professional grade.
