Lenze Industrial Inverter Display Panel
This was one of my first LCD designs. Again I was responsible for the electrical, PCB, LCD and mechanical designs. This was a custom LCD display that was to fit into a plastic molding. The LCD was a separate custom design that I put together including the metal bezel.
The remaining electrical design was conventional surface mount tech, as can be seen in the photos of the completed unit. Some push buttons and LEDs completed the design.

In order to make this stack correctly, the plastic molding had indents and protrusions to ensure alignment. The photo below shows this detail.

ABB Industrial Controller Display Panel
I worked at Three Five Systems for five years. I was the only engineer in the UK office and in my time there I did the electronic design, PCB layout and the plastic molding design.
This assembly is the front panel for an industrial controller. It consisted of 6 dual digit displays (14 segments), and a bar graph module. Both of these modules are custom assemblies, so I had three PCBs and two plastic moldings to design.
