Printed Circuit Boards(PCBs) Printed Circuit Boards are circuits that are compacted into a small board. Printed Circuit Boards are used to connect a device, or cells, to an interface like the lock in amplifier.

Printed Circuit Boards(PCBs) The circuit boards we have created have all been created in Eagle, a software that is specifically made for designing PCBs. In Eagle, you must start off by making a schematic for the software to know what connects to what. 8 Pin Switch 10 Pin Sockets BNC Port

Printed Circuit Boards(PCBs) Once you are done with the schematic, you press a button that transfers you to the board layout. The pieces are off to the side and you put them on to the board where you want them to go. Although this may sound easy, it is like a complex puzzle. BNC Port 8 Pin Switch 10 Pin Socket

Printed Circuit Boards(PCBs) Once you have everything where you want it on the board, you add a silkscreen. The silkscreen tells the board factory what you need to be printed on the board.

Printed Circuit Boards(PCBs) When we receive the board from the factory, we will need to solder any pieces onto the board that we need for our studies. BNC Port 10 Pin Socket 8 Pin Switch

Printed Circuit Boards(PCBs) Once we solder the pieces on to the board, it is ready to test with the cells. BNC Port 8 Pin Switch 10 Pin Socket
