Consultancy
For all but the simplest projects, the first step is research. This can involve a review of current technologies and competitor projects, the choice of appropriate products, and investigating the cost and availability of components. This important phase of the project is essential but time consuming. We can help with unbiased advice and information and leave you with time for other tasks.
Design
With the research phase complete, work can commence on the design. Modern digital components often come with copious application notes and designs that save much trial and error and increase the chances of getting the design right first time. The process follows three steps:
First a schematic is created, which is a human-readable diagram showing the interconnection of the various components. The relationships created in the schematic are used by the design software in the next stage.
The information in the schematic is used to layout the components on a printed circuit board. Simple designs can be realised on a two-layer board with more complex, or tightly spaced designs requiring more layers. The layout of the PCB will often vary greatly from the schematic.
Prototyping
In almost all cases, it will be necessary to test and refine the design to ensure that it performs as expected. This usually involves ordering a small number of test units that are assembled by hand. This can be the most exciting stage of the project and you may wish to carry out this phase yourself. However, if you require assistance with organising the fabrication of the test boards or assembling them, we can help.
Testing
Testing may be as simple as ensuring that all necessary connections are made. More likely, is that the design will involve some sort of antenna, in which case matching will be necessary. If you require bespoke firmware, this will need to be written and tested on the device. Writing software tests, although not difficult, can be time consuming. Unless you are a business or dedicated hobbyist, you may not have access to the necessary test equipment, which can be costly.
We can support you with most of your testing needs.
Manufacture
It can be practical to manufacture small runs of up to around 100 units using prototyping facilities. Beyond this, a specialist manufacturer is required. At the moment, we do not offer this service directly, however we can help you find the right manufacturer for your project and deal with the process for you. PCB manufacture, like any industry, has its own language and it can be daunting to be faced with a question from the fabricator that may be difficult to understand.
