PCBs Only

We make the PCBs easy to manufacture by providing component identification and ensuring that the components are well seperated.
On the underside of the board the pads are large for ease of soldering and again where possible well spaced from adjacent pads. A solder resist layer is present to ensure that the solder only goes on the pads, thus preventing unintentional solder shorts between tracks.
