PCB fabrication, assembly, and free award-winning CAD design software.

Leading the industry for over 40 years as the preferred prototype and production PCB solutions provider for design engineers.

From Start To Finish – Design to Assembly 

It's no secret: your prototype costs you quite a bit of money to produce. Most of that expense is in the components, not the fabrication of the board. Still, if the board's not right, your design's not right. That's why Sunstone Circuits offers the following standard and add-on manufacturing features for your board fabrication:  

  • Less than 0.05% return rate on all PCBs manufactured
  • Our 100% guarantee on manufacturing defects
  • Optional Engineering Review to analyze and report on any manufacturability issues with your design as submitted
  • Flying-Probe Electrical Test: comparing your PCBs electrically to your submitted Gerber files
  • Self-service DFM checking with our online DFMplus service
  • One financial transaction for your boards and assembly when you select bundled assembly

Screaming Circuits specializes in building your short-run, one-off and prototype PCB assemblies, with rapid turn times and instant online quoting and ordering. Whether you prefer "Kitted" assembly or "Turnkey", Screaming does both - and with multiple awards for customer satisfaction and quality to prove it. Not only that, but Screaming Circuits will guarantee on-time delivery, ensuring that you get what you need, when you need it.

When all this is combined with the years of experience and professionalism shared between Screaming Circuits and Sunstone, you can be confident that your PCBs have been fabricated and assembled exactly to your specifications. Which means, of course, that any bugs you're chasing in your prototype won't be a stray short, open, malformed through hole or other manufacturing or assembly anomaly... Instead, you can turn all your attention to testing and verifying the circuit design.

All this is just one more way Screaming Circuits and Sunstone Circuits work seamlessly together to remove potential design issues from your prototypes - getting you through development and into production that much faster.

  • When I arrive at the office this morning I was blown away to find that there was a box waiting for me from Sunstone, and it had a complete new set of boards inside. You have amazing customer support and responded to my problem with amazing speed, proven by your ability to turn out a new set of boards and ship them out in a single weekend. Thank you so much for taking the time to do this, I greatly appreciate it.

  • My first experience in this industry could not have gone any smoother. Beautiful quality and fantastic people to work with. Quick turn around, too! Thank you Sunstone!
    Dan Nardini, MBL
  • Thank you for providing such a good service! I use Sunstone Circuits as my go-to for prototypes and one-off PCB spins. The variety of services that Sunstone provides helps me to reduce cost during the development stage of a product, and to construct quality, one-off board assemblies for devices such as test-fixtures. Populating prototype PCBs in-house provides quick feedback on designs, and the opportunity to bring a board up one section at a time with rework if necessary. It also helps to assure that the documentation our local CMs will be receiving is in good order before the build is outsourced. All of this helps us to locally produce reliable products in a timely fashion, and Sunstone Circuits’ services are an important part of this process. Regarding a case study, now is probably not the time. Our company is growing at a rapid rate, and our processes are adjusting to meet those needs. Thank you for reaching out to offer the possibility for publicity that this could provide, however! I’m glad to know that we are one of your top customers, and I look forward to doing more business with you and your team soon.

    Paul Spears, Pedalrepairs.com
  • "We received the order on time and the boards are exactly as specified – excellent work! The order process was absolutely painless, and we had no holds or other issues. The ability to have you guys convert from my original Altium board file was extremely useful. We will certainly continue to use Sunstone for future circuit board orders."

  • Hi Bob, and everyone at Sunstone Customer Support. You guys are fantastic. I just received the box of goodies, and it made my day. Your PCB123 software is so much easier to use than any other software I've tried, nobody else can come close to your fast lead times, and your customer support has always been incredible. I would (and do) recommend you guys to anyone looking to design a custom circuit. Thanks again for all you've done over the years. I have some new designs in the works, and will definitely be ordering from you when they are ready.
    Mike Bell, ARCON Welding Equipment
  • Thanks for the e-mail. You are the best and I’m loving our experience with Sunstone so far – smooth ordering, responsive staff, discounts and shipping a day early. I could not be happier and just wanted to express that to you directly!! Hopefully I got the design right this time and we can place a production quantity order in the near future. Thanks again!!

  • Your new web site is great and I did use your Customer Support Team this morning to get on the new site and get the new quote. Tim was absolutely great, I wish all the Vendors I deal with worked as effortlessly and helpful because my order and prep for it went smoothly this morning.
