Quick Contact


I approached Sierra after being referred to them from another PCB designer. What impressed me was that they were more than willing to take a complex PCB requirement. The PCB assembly they provided was small, lightweight, but provided the amount of power needed for our computer product. Great experience.

I liked Sierra’s quick turn PCB assembly services. They provided a prototype within a few days, and it worked without a hitch. I was extremely satisfied with the quality of the PCB. Their prices are great too.
