From Prototype to Production, the simple choice is Sunstone.

Every project goes through the feedback loop: Concept to design, to prototype. Rinse-and-repeat as the prototype tells you what's wrong with your design, and you make change after change after change, spin after spin, never building the same thing twice....until you have something you can take to production. And then? Then, Change is your enemy. Change means you lose control of the consistency you need for your product. Change means you lose repeatability.

The question to consider is this: why would you not keep your production with the same people who sweated your prototypes with you? Who else knows as much about fabricating your board as you know about the design details? Why would you jump to a production house just because you're done prototyping?

At Sunstone, we use what we learned from your prototypes to bring simplicity and reliability to the transition from prototype to production.

In the early stages, designers are more concerned about proof-of-concept. The prototype boards are, by intent, nothing like the final product board. Easy access to key testpoints for circuit debugging, for example, are a priority in the early days. But as the design is refined; the design team's attention turns to production concerns: reducing layers; simplifying the BOM; fixing signal integrity issues; etc. 

Sunstone is there with you through all of this refinement, right up to the moment you sign off on the last spin as production-ready

Take your production-ready design to a production board house, and it's a brand-new design to them. There's tooling to be done, design notes to verify, and all that. The production house will charge you an NRE charge for this prep work. 

But here at Sunstone, your production-ready revision is simply the last board we built. We already know what to do to fabricate your design successfully. To move to production with Sunstone is simply to reorder as a production run. It's really just that simple.

  • 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.

    Mark Kuhn, Oat Foundry
  • The process was easy and fast. You guys killed it!! Got the pcb looked and worked great. Totally would recommend you guys. Thanks.
    Paul Spears,
  • "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.

  • 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.

  • I’ve been using Sunstone for decades now, and just like all the projects I’ve done with Sunstone, there were no surprises. Everything went just as it was supposed to, and the board is performing fine. You’re lucky to work for such a great company. In my experience it’s very rare to find the kind of competence and compassion that Sunstone has. You might find one, or the other, but not both. Very rare. Anyway thanks again, if I could I would be working with Sunstone every day.

  • The boards were perfect, and I built up six, all of which work. I even had to remove some difficult components after I'd soldered them, which required a LOT of heat, and there was no trace delamination! I also learned what changes to make for future PCBs to improve my ability to solder thru-hole components. Sunstone is GREAT, even going the extra mile in both preliminarily reviewing the board after hours on the day of submission (because my designer was leaving on vacation the next day) and the next day making changes to the solder mask that should have been done on my end (after my designer had left!), and I'm recommending Sunstone to anyone I know who needs fast turn around. Thank you once again.
