In our previous schematic article, it might appear that with so much detailed information anyone could perform the layout phase. However, a detailed schematic is only the foundation for the PCB layout and not just anyone can create a successful PCB layout. Layout must be performed by someone who understands industry standards for design and manufacturing as well as the depth of knowledge required for incorporating design for excellence. This individual is analytical enough to be able to sort through vast amounts of data, but creative and free-thinking enough to see many alternative ways to complete a design and have the intuition to choose the best one. Simply put, a designer of PCBs is a person of renaissance. Here are some steps to place you on the path to successful layout setup and placement.

What to Bring to the PCB Design Review
Even the simplest layout will require deliverables for assembly including custom paste stencil and a bill of materials to associate the correct component for each location on the board.
Electro-Static Discharge and How You Can Contain It
At one time or another, we’ve all shuffled across a rug and touched a door handle or other metal object only to feel the zap of static electricity.
Using Lasers to Fabricate Printed Circuit Boards; The Light Work
Lasers have always been around. At least, it seems so when we can read how they were used on the Apollo missions. Lasers were part of a range finder for the space ships to know their precise altitude.
Thermo-Electric Cooling, A Counter-Measure to High Current Density on a PCB
Thermo-electric cooling, or TEC, has been seen as a breakthrough in small refrigerators that do not consume a whole lot of power.
Dealing With the Shock and Vibration of Your System
Have you ever dropped your phone? Of course, that is a rhetorical question. How many screens have I cracked (?) would be a better one. It is pretty amazing that the devices continued to work.
