Electronics Design

From the specifications, the electronics design is undertaken using developers which are as experienced as the project is difficult. Often for simple single board microcontroller designs, more junior designers are used with an experienced supervisor. In the case of more complex designs with multiple add on boards, a better more experienced designer is required. Generally though, microcontroller based designs and small microprocessor designs or simpler FPGA designs do not require the best and most experienced designers.

As in the mechanical design case, risk reduction at early stages is a priority. An example of risk reduction could involve a trial hardware layout of the components on the circuit board to make sure that they will all fit. The goal might be to make a 4 layer board, maximum to keep within the BOM cost range. The trial layout would determine the physical layout, confirm that the heat could be disapated and all the components could fit comfortably using the preferred packaging approach (ie SMT, BGA, …) and that the other constraints were met.

System Integration

The designers will have periodic meetings to ensure that the two halves of the design are working together well. Often with plastic cases, the main concern is getting the connectors exactly aligned with the case and the case’s closing mechanism working well. With metal cases, issues of shorts between the board and the case can be problematic particularly given that the size of the box generally needs to be a minimum size.

At then end of the integration process, and after the testing process, a gold unit is achieved. It is this gold unit along with schematics, gerbers, and CAD drawings (complete with final tiny modifications) which are passed to manufacturing.
