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.

  • "So far everything we have ordered thru you guys has come out exactly like designed and have not had any problems. One of the main reasons I have chosen Sunstone Circuits is the fact that I can order the PCBs without silk screen and without soldermask from your web site, most other places I would have to call the vendor to get this done, plus your prices are good."
    Robin Santini, Zyvex
  • "Customer service agent assisted throughout entire order process. Outstanding support!"
    B. Kilday, - Warrenton, Virginia
  • "You guys help me out a lot when time is tight and Managers begin to breath fire....I only have so many fireproof silk shirts...Thanks!!"
    P. Geantil, - Carlsbad, California
  • "Just got the first boards...perfect!! Thanks for the help! What an easy process! Zero to finished boards in 2 weeks, including learning curve. I was dreading ordering a PADs or OrCad package for $5K and then spending weeks learning it. Your approach really is a good option for the R&D engineer."
    Bruce Sargeant, Device Labs
  • "Sunstone's CAD software, PCB123, really does all the things I wanted -- and much more!!! It reduced the number of traces by about a third - and it looks very pretty! The new libraries are GREAT too! You really blow the competition out of the water!! And your support is FIRST RATE! Thanks for all the help! Will submit the board tomorrow!"
    Brad, www.presys.com
  • "Great service. Low price. Good quality. What else is there to say?"
    Todd Perrodin, Microchip Technology
  • "I liked that I didn't have to re enter all the board information since I'd ordered the same boards in the past. It was a really easy process to re order."
    M. Childers, - Tigard, Oregon
  • "Sunstone Circuits is one of the most professional companies I have done business with. As I have said before, we have not done this before and working with you and your company has certainly made this an easier journey. Thank you for all of your efforts."
    Sy Sajjad, XBiometrics
  • "Thanks (Sunstone) very much. And isn't it about 1 am over there?! I'm impressed. I don't expect replies from U.S. west coast companies until I'm about ready to shut down myself on this side of the world."
    Jim Donnett, Bio-Signal Group
  • "Easy re-order! You've always been a great resource for me on the many prototype and low qty pcb builds I do."
    D. Burton, - McMinnville, Oregon
  • "Many of my students and colleagues don't have ready access to PCB fabricators that we can trust. Over the years we've relied on Sunstone to consistently deliver design advice, technical support and solid PCB products for all our research and projects. Sunstone has never let us down, that's why they are our partner of choice for research projects and product development efforts."
    Jeevan Persad, Electronics Product Designer
  • "AWESOME Technical and Customer service!! AWESOME, THANKS GUYS. Will be looking into assembly in near future."
    B. Moretz, - Lubbock, Texas
  • "Your customer support people are great! The response time and knowledge is excellent. Probably the best I have ever dealt with."
    P. O'Hanlon, - Kirkland, Washington
  • "I used your excellent products to design a series of circuit boards that went into an oceanography instrument this spring. We have just completed a busy summer of cruises and the instrument preformed perfectly, without a hitch. Were it not for your company I would not have had the design freedom and capability to produce the boards within our meager budget. I look forward to this next design. Thanks a million."
    Glenn H. May, Scientific Applications
  • "Using Sunstone Circuits has been fast and easy, ordering online for the first time user like myself was very user friendly, and the tech support was top notch. I have used other companies in the past and their quality of product was quite disappointing. I just received your boards and they look excellent, I haven't found a reason to use any other company but Sunstone for my next project."
    Ryan S. Nichols, Indiana University Cyclotron Facility
  • "It is difficult to find in one company a high level of all these 4 ingredients: 1) Quality (In over a dozen jobs, not once a bad board (out of 100's of boards)). This is the most important ingredient, since a bad prototype or production board represents an enormous loss of time. I have changed PCB houses as a result of this factor alone. You are doing a superb job so far. I plan to remain a loyal customer for as long as you keep turning out such quality in the boards we receive. 2) Price (Prices are generally lower compared to others, even comparing with very low cost houses) 3) Service (Willing to do special requests with a smile and efficiency-Rob in Pre-Engineering and Al in Sales are examples) 4) Easy to use (Immediate quote and easy ordering system) both, for prototype and production runs."
    Marcelo Jakubzick, MC Miller Co.
  • “I've been designing circuits for over 45 years. You guys are amazing; the DFMplus service is exactly what I needed!”
    Mike Fleming, Electrical Engineer
  • "Very smooth reorder process. Thanks...You took this job away from Advanced Circuits because you allowed a stepped matrix, of PCBs that was not allowed by Advanced Circuits. I like this approach - - just offer the service; let me figure out how to best utilize it to my advantage."
    J. Hamilton, - Wichita, Kansas
  • "Well organized site, very much appreciate the "order wizard" step by step ordering process."
    J. Branch, - Camas, Washington
  • "Your product is amazing and I will definitely use it again and recommend it to friends/companies. The concept of a truly integrated schematic, layout, followed by pcb delivery, is fully realized in your CAD software product. This method of design and manufacture of pcb has increased my ability to deliver, by reducing cycle time to develop the boards, while also reducing risk by using your integrated product. I also wanted to say a big thank you to the team there and especially Joe Phelps for the incredible and efficient support. Thanks again!"
