Bermondsey Electronics work in the middle of the product design world. Imagine for example if you wanted to created a pen that when you wrote recorded the writing and sent it via Bluetooth to a computer nearby. The product would be designed by a product design house. They would create the look and feel, size and shape. You would then go to an electronics company that make the actual electronics and get them to design the inside of the pen on a PCB (Printed Circuit Board). All the components on this PC.
