Privacy Policy

What is unique about Sierra Assembly Technology’s Privacy Policy?

Unless you give us written permission, we will never sell or share information pertaining to you or your company.

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.

Sierra Assembly Technology has a great group of people to work with. They are open to almost any request and always get the job done quickly. I’ve been in some tight spots before and needed certain products within a small time window, and Sierra has always been reliable.”
