  • 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.

  • 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.

  • 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.

  • 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!!
