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.

Cooperation
We provide service to our customers from prototype through production, meeting their time to market requirements. No order is too small, and any lead time is possible. We thrive in a high mix, quick turn environment. Our on-time delivery, for standard as well as complex technology is widely across many industries.
Testing Procedures
We perform multiple quality assurance procedures before shipping out any board. These include:
Visual inspection
X-ray Inspection
AOI (Automated Optical Inspector),
ICT (in-circuit test), and BGA Rework
Functional test (test modules need to be supplied) .
Quick turn lead times
If all the parts are available, normally the full turnkey pcb assembly job can be finished within 5 to 10 days in our factory. This means that the order can be delivered within three weeks once turnkey job start.
