At Sierra Assembly, each component of HDI PCBs is stringently tested to ensure maximum performance. We employ in-circuit testing systems such as GenRad 2283 & GenRad 2280S, bed of nails with fixture, and open express equipped & boundary scan capable to check shorts, opens, resistance, and capacitance, whilst ensuring that the PCB is rightly assembled. Moreover, our X-ray testing such as Vision Systems, Scienscope, Microscopes, and Clear view detect hidden PCB assembly defects.
As mentioned earlier, HDI PCBs are widely chosen for applications that call for compact, yet higher functional boards. These boards help minimize the size of the application, and enhances their electrical performance and lowers power consumption. Also, they ensure stable voltage rail, minimal stubs, and lower RFI/EMI. Since, we employ quality systems such as ISO 9001 to develop well-defined PCBs, our customers can rest assured with the quality of the final assembly. With us, you will find dedicated sales and technical support teams who dedicatedly meet ever-increasing customer demand for low cost, and high-quality PCBs.
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.
