PCB Design

If you have a schematic or a drawing, but do not have time or tools to complete the design, we can help you.

From 25 to 25,000+ pins, our PCB Design team of in-house electrical engineers can handle your toughest designs. These engineers are experts in PCB Design Services and specialize in using Allegro (a Cadence tool) and PADS (an Innoveda tool).

There are 11 steps to the PCB design process & work flow which we cover in the pcb designing guide.

Step 1: Finalize your Circuit Design

Step 2: Choose PCB Design Software

Step 3: Capture Your Schematic

Step 4: Design Component Footprints – Once the schematic is complete its time to draw the physical outline of each of the components. These outlines are what are placed on the pcb in copper to allow the components to be soldered to the printed wiring board.

Step 5: Establish PCB Outline – Each project will have restrictions related to the board outline. This should be determined in this step since an idea of component count and area should be known.

Step 6: Setup Design Rules – With the pcb outline and pcb footprints complete, it is time to start the placement. Before placement you should setup the design rules to ensure that components or traces aren’t close together. This is only one example as there are probably hundreds of different rules that can be applied to a pcb design.

Step 7: Place Components – Now its time to move each component onto the pcb and begin the tedious work of making all those components fit together.

Step 8: Manual Route Traces – It’s necessary to manually route critical traces. Clocks. Power. Sensitive analog traces. Once that’s complete you can turn it over to Step 9.

Step 9: Using the Auto Router – There are a handful of rules that will need to be applied for using an autorouter, but doing so will save you hours if not days of routing traces.

Step 10: Run Design Rule Checker – Most pcb design software packages have a very good setup of design rule checkers. Its easy to violate pcb spacing rules and this will pinpoint the error saving you from having to respin the pcb.

Step 11: Output Gerber Files – Once the board is error free it’s time to output the gerber files. These files are universal and are needed by the pcb fabrication houses to manufacture your printed circuit board.

After PCB Design, we can also take your design to reality with PCB fabrication and PCB assembly services. Just need email me: hualan0755@hotmail.com
