The printed circuit boards have become advanced, due to several developments in their manufacturing techniques. But this is not all. To make the boards and the components placed on them capable of performing even in critical conditions, they are subjected to several tests, and inspections. This not only helps remove the defects at an earlier stage, but also improve the overall performance of the components on the boards.
Different types of stress tests are being implemented today, to check the performance of components. The burn-in test is one such test, in which the components are stressed, and their performance is tracked. Failures are detected and then resolved. So, a burn-in board is a printed circuit board, which is specially designed to be capable of withstanding the burn-in process. There are several manufacturers in the US, who can provide you these burn-in boards. However, very few among these are capable of manufacturing high-quality boards, which are suitable for burn-in processes. Sierra Assembly is one the most preferred and reliable names, when it comes to manufacturing quality burn-in printed circuit boards.

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.
