Hardware design starts from the requirements document. Then a detailed specification is created which drives the schematic drawing phase. An often neglected part is the selection of parts to accomplish an electronic design. Selecting parts with high availability and less lead delivery times is an important task. Another aspect is selecting the components packages as these affects the board (PCB) area and the assembly process. A denser PCB may require higher manufacturing class and thus increase production costs. A good understanding of the PCBA production phases is required to have an efficient design that can be produced smoothly in quantities without disruptions.
Producing is not the end of the line though. Testing is another major factor which should be considered. There are many test strategies employed depending on technology used, production quantities and yield.
Understanding the above issues explains why there are many failures in kick-start type projects when it comes to hardware. Take the wrong decisions and you may end up well out of your estimated cost and time budget.
Our experience in hardware offers many years of expertise in embedded systems design starting from specifications down to product support. Our portfolio of work includes dc motors, sensing, microcontrollers and FPGAs.
