Requirements Capture

The Requirements Specification defines exactly what will be created. Appian creates this formal list from the discussions and documents provided by you and we add lower level detail as required.

  • Capture the requirements

  • Add comments and clarification

  • Agree with the customer

  • Sign off product on completion

Schematic Capture

The Schematic designs are a logical representation of the circuit board design. It holds the component information and the connections between them.

  • Select components

  • Create and add new parts to CAD libraries

  • Create the schematic

  • Export schematic to circuit board layout tool

Circuit Board Layout

The circuit board layout is the physical representation of the design. 

  • Create board outline

  • Place components

  • Connect component pads, add power planes and thermal relief

  • Optimise and tidy routing and placement

  • Create manufacturing information and list of material

3D Representation

3D View and Video

Appian can create a 3D view and video of your circuit board. This provides a great visual experience of how the board will look.

3D Export

Appian will create a 3D export of the board to allow either our own industrial designers or yours to import the board into the mechanical design to check it all fits nicely. 

Prototype Manufacture and Test

Once the circuit board design is complete, Appian will manufacture the first prototype boards. This is usually between 3 and 5 samples to allow testing to begin.

Bare board


Appian will get the bare board manufactured using one of our trusted PCB suppliers. Depending on the complexity of the design, the board can be anywhere from a single layer up to around 16 layers. Most designs are in the range of 2 to 10 layers



Appian will either assemble the board in house or using one of our preferred assembly houses. This tends to be driven by board complexity and quantity. For high volume products Appian will interface with the assembly house at an early stage to ensure the design is optimised for their assembly line.



Once the board is assembled and inspected, testing can begin. This usually starts with some basic measurements prior to powering the board. Power supplies and clocks are checked and then communications with any programmable parts such as microcontrollers or FPGAs. Detailed testing will then follow to ensure the board meets the specification.
