Introduction
PCB Assembly is a process that requires knowledge not just of PCB components and assembly but also of printed circuit board design, PCB fabrication and a strong understanding of the final product. Circuit board assembly is just one piece of the puzzle to delivering the perfect product the first time.
San Francisco Circuits is a one-stop solution for all circuit board services so we are often entrenched with the PCB production process from design to assembly. Through our strong network of well-proven circuit assembly and manufacturing partners, we can provide the most advanced and nearly limitless capabilities for your prototype or production PCB application. Save yourself the trouble that comes with the procurement process and dealing with multiple components vendors. Our experts will find you the best parts for your final product.
