I have been amazed at the level of service you and everyone else at Sierra have provided. I have had 95% of all my boards produced through Sierra because of the high production quality and the attention to customer's needs. I look forward to continue working with you and I keep recommending Sierra to anyone needing PCB services.

Thank you for everything!

..we have two senior executives here, both VPs, who once were associated with the board building process. When they heard how fast Sierra can turn out boards with the quality that Sierra has, they were amazed and a little disbelieving at first. They have never seen such good quality come with such quick turn around time. Kudos to the Sierra Circuits team!

Great job. First time I've used Sierra Circuits. Silk screen was incredible, the smallest text was readable. Thru-hole drills where dead center. Solder mask, perfect. Nothing else I can say, just perfect, very perfect. I'll be using your company from now on.
Mike S. guys are a 1st class company and great to work with.
