DDR ROUTING

We handle DDR routing designs on a regular basis. DDR routing requires understanding:

✓

Length matching concepts
✓

Controlled impedance
✓

Propagation delays
✓

Address/control signal channel grouping

To ensure length matching of signals in the same group, we route them on the same layer.

FINE PITCH BGAs

Fine pitch BGAs, such as 0.4 mm, come with their own challenges. The drill-to-copper distance needs to be maintained and as traces cannot be routed on the top layer due to limited pad-to-pad distances, blind and buried vias with via-in-pad technology must be used. In such cases, multiple laminations are required during fabrication. A close coordination between the production and PCB layout design teams is required.

With our production and layout services under one roof, we can deliver complex designs with faster turnaround times. We drastically reduce the usual back-and-forth between the layout engineers and the fab house.

COMPONENT PLACEMENT

Our design engineers optimize the placement of your components by analyzing the signal flow. We start by locking connectors and other important components as well as identifying CPUs, communication chips WIFI, Bluetooth ethernet, and sensor chips. We then place decoupling capacitors, clock crystals, and series resistors close to the main components.

Component placement optimization reduces the trace lengths and the number of vias, thus the overall cost of the board.

CONSTRAINT SETTINGS

Constraint setting is required for a number of reasons. For instance, we must set the trace width and space for controlled impedance traces. It also helps reduce crosstalk between traces. The spaces between traces are set typically 2W and 3W, where W is the trace width.

THE TOOLS

OUR CUSTOMERS USE

WHY SIERRA

✔

Modern layouts, like high-speed and HDI designs, are very complex and need multiple years of experience. We have listed a few above and there are many more PCB layout design parameters which require high-level skills.
✔

With design, manufacturing and assembly under one roof, we eliminate miscommunication between different vendors therefore making you save time on your prototype.
