Printed Circuit Boards (PCBs) are employed in nearly every electronic product used today. Looking similar to a tiny city block, they commonly consist of flat structures that are packed with the terminals and pathways used to facilitate the transfer of signals from one place to the next. In other words, PCBs are the medium used to connect electronic components to one another in a controlled manner. As a result, it should come as no surprise that they can be found all across aerospace operations, being used to facilitate much of the functionality of electronic systems on board spacecraft. But what separates the PCBs you might find in your mobile phone from those used in aerospace projects? The answer comes down to a strict set of standards that ensure the PCBs used on space vehicles are reliable enough to stay effective in what can often be unusual working conditions. For more information, keep reading as we discuss the design and assembly principles that make these PCBs approved for avionics.
